As the name implies, such an installation can provide a facility with both electricity and thermal energy, if necessity. In more detail, what is gas-piston mini-CHP, the principles of their operation and the advantages of installation at enterprises - https://cutt.ly/HbHs5t8


Reliable off-grid power supply

Self-sufficient energy supply: Granjas Carroll pork processing plant has a state-of-the-art independent power plant

May 06 2021 | 17 min read

Illustration

The Granjas Carroll pork processing plant is located 2400 m above sea level, surrounded by wilderness, far from the stable traditional power supply centers. The plant can handle up to 1.5 million pigs per year. Therefore, it is critically important for him to have reliable, constant energy without fluctuations in voltage or frequency. This is necessary for stable power supply and refrigeration.
The local provider cannot fully meet the plant's energy needs. Therefore, the company was faced with the task of building its own power plant that could operate in a completely autonomous mode and cover all the energy needs of the plant.

Then the Granjas Carroll team turned to the local expert on distributed energy systems Electriz, S.A. de C.V. After analyzing the situation, Electriz experts recommended installing 4 MTU Series 4000 gas generators and 1 MTU Series 4000 diesel generator set. All of them work under one common control system.

Built in just a few months, the facility was commissioned at the end of 2018 and has been operating without interruption since then. In the future, it is planned to use the heat of exhaust gases, oil cooler and mixture cooler for efficient production of steam and hot water. They will come in handy in production processes.

What is a stand-alone power plant for a pork grower?
The four gas units used in the plant are 4000 series 20-cylinder natural gas systems that produce a total of 7.7 MW of electricity.
One 4000 series 16-cylinder diesel generator system with 2 MW electrical output to ensure long-term stability of the unit. The diesel unit will operate continuously at up to 10 percent load to minimize fuel consumption, allowing natural gas units to generate more power. The mtu MCS main control panel integrates unit control and remote control. All systems operate in isolation from the mains, providing a reliable, stable and efficient power supply to the entire facility.

A stand-alone power plant perspective
With flexible MTU systems, the plant will be able to double its capacity in the future - even by connecting the power plant to the grid to provide additional power for the surrounding population.
At a later stage, there are also plans to use biogas from animal waste as another source of fuel to operate the plant. “There are many good companies, but when you have a problem and the company proves to be reliable, responsive quickly and thoroughly, you don't want to do business with anyone else,” said Daniel Salazar, CEO of Electriz, S.A. de C.V. “Efficiency and affordability are key to the energy business, and MTU solutions offer both.”

Cogeneration is the production of heat and electricity from a single source, usually natural gas. Today it is possible with the help of gas engines with efficiency 90%.Initially, cogeneration plants (CHP) were intended only for large objects - greenhouses in several acres or entire residential neighborhoods, now smaller objects - hospitals, hotels, office buildings and factories - can benefit from CHP.
For example, MTU offers cogeneration modules with an electrical power from 120kW to 2,150kW and from 730,000 BTU / hour to 7.790,000 BTA / hour.It is advisable to install a cogeneration installation on your object?

Most food productions need both in electrical and thermal energy. Cogeneration installation, which aims to combine heat and electricity production, can partially cover high demand technological lines for heat and electricity.
For example, ice cream producer Langnese generates heat for the production process using the Rolls-Royce cogeneration plant. It is equipped with a 16-cylinder engine MTU16V4000 type L62, which works on natural gas generates 1,719 kW of thermal energy and provides the efficiency of 87.1% by optimizing the use of heat.
A malt plant DURST MALZ uses 2 cogeneration plants from Rolls-Royce on its ownProduction facilities since July 2011. They provide a plant at the same time and warm and electricity. CO generational installations GC 357 N5 produce about 1 MW heat, which is used for dryingmalt. Approximately 700 kW of electrical energy, which the installations are generated in addition to heat, enters the overall power grid of the plant. Thus, the installation efficiency is about 90%.

Categories of equipment for backup energy

Illustration

Reserve diesel generators are necessary on those objects where continuous power supply with a stable voltage is important.

March 11 | 5 min read

Illustration

Reserve diesel generators are needed on those objects where continuous power supply with a stable voltage is important.
They can be divided into 2 large groups:
• Standby Power (backup)
• Mission Critical Power (emergency)

Standby Power

In case of disconnection of the power grid or voltage drop, this DGU class increases power in a few seconds to restore the flow of electricity to consumers. Reserve DSU must ensure maximum reliability, high load capacity and rapid response. In addition, they must satisfy various power needs if necessary.
Suitable for residential complexes, industrial facilities and even whole areas of cities.

Mission Critical Power
Emergency diesel generators are needed at facilities where power supply interruptions can lead to large financial losses or threaten the lives of people. They must have the most accessible capacity and high medium load factor. For example, MTU solutions have the best medium load coefficient (more than 85%)
Suitable for airports, hospitals, telecom operators, Internet providers and data centers.


Categories of PowerGen equipment

As of 2020, the deterioration of power grids in Ukraine was about 80%, and in some areas - up to 100%. This data is provided by civil society organizations that unite operators of the electricity distribution system.

Illustration

As of 2020, the deterioration of power grids in Ukraine was about 80%, and in some areas - up to 100%. This data is provided by civil society organizations that unite operators of the electricity distribution system.
For end consumers this is fraught with:
• interruptions in the supply of electricity due to emergency situations
• increase in tariffs, because constant repairs are expensive for operators

And, if for the population this is only an annoying inconvenience, then industrial enterprises suffer colossal losses because of this. This is why there is a growing interest in power generation equipment.
In general, it can be divided into 3 groups:
• Continuous Power
• Prime Power
• Grid Stability

Continuous Power
The equipment of this group works as part of the traditional power grid. Such installations have a constant load and generate additional electricity. A variety of installations - CHP (cogeneration heat and power) - produce both electricity and heat energy at the same time.

The Continuous Power category is suitable for facilities that need complex energy supply. For example, airports, residential complexes and even entire villages

Prime power
If access to the traditional power grid is not available or it is significantly difficult, then you will need installations of the Prime Power category. They are under variable load and are suitable for the objects that are being built. For example, new metro stations or residential developments on the outskirts of cities

Grid Stability
Renewable energy sources significantly reduce CO2 emissions into the atmosphere. But the strength of the wind and the light of the sun are fickle and unpredictable. Therefore, the compensation of fluctuations in the power grid and its stability is the main task of the equipment of the Grid Stability category. Such installations are able to quickly and repeatedly turn on, therefore they are in demand by producers of "green" energy.

But for some businesses it is economically unprofitable to generate all the energy they consume on their own. In this case, you can reduce the risk of blackouts by using equipment for backup power supply of Standby Power and Mission Critical Power categories, which we will talk about in the near future.

The Rolls-Royce Power Systems Division is expanding the portfolio of its product and solution brand mtu to include uninterruptible power supply systems. From 1st February, the flywheel energy storage power supply systems have been marketed as mtu Kinetic PowerPacks. The manufacturer Kinolt taken over in july 2020 has been incorporated in Rolls-Royce Power Systems and is now the competence centre for dynamic uninterruptible power supplies.
For especially critical installations such as data centres, hospitals or industrial plants with sensitive production processes, the mtu Kinetic PowerPacks provide continually high energy quality and eliminate parasitic effects on the power grid. In the event of failure of the (usually public) power grid, the systems reliably safeguard the energy supply without loss of power or voltage in the microgrid.
mtu Kinetic PowerPacks combine the function of an uninterruptible power supply with an emergency power supply using flywheel energy storage and modern diesel engines. The technology offers high quality supply to the consumer grid combined with compact dimensions.
"As compact UPS systems, the mtu Kinetic PowerPacks represent a substantial addition to our range of practice-proven emergency power gensets. We can now offer our customers complete energy security solutions for their safety-critical installations that are extremely economical in terms of both acquisition and operating costs. The sales and service organisation will gradually be incorporated in the Rolls-Royce Power Systems service organisation. As a result, customers will have access to an even closer network," says Andreas Görtz, Vice President Power Generation at Rolls-Royce Power Systems.
Integration into the mtu product range had already been announced in July 2020 when Rolls-Royce took over the Liège (Belgium) based manufacturer Kinolt. Established in 1984 as Euro-Diesel, the company is among the market leaders in uninterruptible, dynamic power supplies. Along with incorporation of its products in the mtu portfolio, the new subsidiary has been given a new name. The business formerly known as Kinolt S.A. has been trading as Rolls-Royce Solutions Liège SA since February 1st, thus following the new brand concept of the Rolls-Royce Power Systems Division.

Rolls-Royce is supplying two mtu 16V 4000 M55RN gas engines to Sembcorp Marine Integrated Yard for the construction of the world’s first liquefied natural gas (LNG)-hybrid powered tug. The harbour tug will be operated in Singapore by Jurong Marine Services, a wholly owned subsidiary of Sembcorp Marine. The new LNG-hybrid tug is the first of 12 tugs that Sembcorp Marine plans to design and build to replace the existing diesel-powered ones between now and 2025.

“We are very happy to be part of Sembcorp Marine’s efforts in environmental protection and adopt new green technologies in their operations. The mtu marine gas engines are part of Rolls-Royce's Green and High-Tech programme. Without exhaust gas aftertreatment they emit no sulfur oxides only very small quantities of nitrogen oxide and particulate mass is below the verification limit”, says Chew Xiang Yu, Head of Rolls-Royce Power Systems' commercial marine business in Asia.

This is the first LNG-hybrid tug to be powered by mtu gas engines worldwide. Designed by LMG Marin (Norway), part of the Sembcorp Marine group, to deliver 65T Bollard Pull (BP) with ABS Class, the LNG-hybrid tug is estimated to be completed in the later part of 2021. The main propulsion system of the tug comprises twin 16-cyclinder mtu Series 4000 gas units which will provide a combined total power of 2984 kilowatts at 1600 RPM (revolutions per minute). The new gas engines are able to deliver performance comparable to a high-speed diesel engine. Equipped with multipoint fuel injection, dynamic engine control and enhanced turbocharging, the engines cater for dynamic acceleration capabilities, high power output and reduced emissions considerably below the current IMO III limits without the need for exhaust aftertreatment. The LNG-hybrid propulsion system will be able to provide flexibility to cater for various operational modes and is able to switch between low emission liquefied natural gas (LNG) engines and zero-emission battery power.

The new mtu gas engines are already powering ferries operated by the Dutch shipping company Doeksen in the specially protected Wadden Sea. A Lake Constance ferry operated by Stadtwerke Konstanz will also start operating in 2021 with the new mtu gas engines.

Turning waste to green electricity

How Rolls-Royce (MTU Onsite Energy GmbH) gensets сonvert landfill gas to electricity in Shenzhen, China

November 30 | 3 min read

Illustration

The city of Shenzen is also called the Silicon Valley of China. From 30,000 inhabitants in the early 1970s, the southern Chinese city has grown to more than ten million, with glittering skyscrapers, a modern transportation system and world-class shops. New factories and start-ups open almost daily, driving the boom. But this growth also brings problems with it : energy demand is rising and the environment is being polluted. Power generators from Rolls-Royce now help to solve these problems. Landfill gas is produced at the many waste disposal sites and thus gensets produce electricity.

The challenge of landfill gas
The big challenge: Landfill gas is a waste product that is relatively easy to obtain. Bacteria decompose the organic part of the waste and thereby produce landfill gas. It contains the flammable methane that gas engines run on. However, depending on the type of waste that decomposes, the composition of landfill gas is different and so is the methane content. On average, between 35 and 60 percent of landfill gas consists of methane, the rest is carbon dioxide. And the amount of methane has a great influence on the performance of the engine. If the methane number of the gas is too low, the engines begin to knock: then parts of the compressed gas-air mixture explode even before it has been fully ignited by the spark of the spark plug and the engine's performance drops. 

Using landfill gas produced there during the decomposition of waste, three MTU 20V 4000 L32FB gensets generate almost 6,000 kilowatts of electrical power.
"So far, our gensets have been running very stably at a methane content of about 50 to 55 percent," explains Darren Ding, who supports MTU gas customers in China. 

So far, MTU's gensets have proven themselves under very difficult conditions. The units operate in the most humid and hot environment in China, and the site ventilation conditions are very poor - Xuming, Head of the New Energy department at Micropower, the operator of the plant
Using landfill gas that is generated anyway
The client is Shenzhen Shengshi Energy Co, Ltd. based in Longgang District, Shenzhen City. In recent years, the company has had twelve landfill biogas power plants with a total capacity of 120 megawatts built, and six more are currently under construction. The company feeds the electricity into the public grid. This is because landfill gas is still a large market in China - unlike in large parts of Europe. It is true that the Chinese government is also increasingly focusing on separating and recycling waste. But 70 percent of municipal waste in China is still being disposed of in landfills. "Making use of these gases, which are in any case produced during the fermentation of this waste, is a great benefit for China," says Darren Ding. It's a win in two respects: in addition to the economic gain, the environment also benefits by not letting the landfill gas escape uncontrolled or being flared. And so Darren Ding and his colleagues are working to ensure that more landfill gas power plants in China are equipped with MTU cogeneration units.

By the way: How landfill gas is produced
During degradation processes, gaseous metabolic products are excreted in landfills. Microorganisms that decompose the waste release methane and carbon dioxide under certain oxygen and temperature conditions. At the end of the biochemical degradation process, a water-saturated gas mixture is produced, which is called landfill gas.


E-VEHICLE SUPERCHARGERS IN AUSTRIA MORE RELIABLE THANKS TO MTU BATTERY SYSTEMS

Illustration

Pull over, fill up, drive on – without losing time. What drivers of petrol-powered automobiles have long taken for granted will, over time, become the new norm for E-drivers too. Many utility grids tend to reach overload when having to cope with several E-vehicles being charged at the same time, or with super-chargers that are demanding high power delivery quickly. Now SYNERG-E, an EU-funded tech project, is helping E-vehicle service stations overcome these challenges at several locations in Austria. How? With stationary battery storage systems carrying the Rolls-Royce brand MTU.

November 26 | 8 min read

Illustration

E-mobility is one of industry's most transformative trends and today the focus not only of untiring development work and state subsidizing, but also endless debate. The reasons why E-drives have become a talking point are manifold: increasingly aware of the benefits, more and more people are choosing to swap their petrol-powered automobiles for vehicles with an electric drive. The advantages speak for themselves: energy-efficiency, no local carbon emissions, low running and maintenance costs, and virtually silent operation.

But there is one big sticking point: the infrastructure for public charging stations, which attracts criticism for its lack of charging points and excessively slow and complicated charging. Many local utility grids indeed tend to reach overload when several E-vehicles are being charged simultaneously in one place, or when high power is being drawn off by supercharger stations within a short space of time – as frequently happens in busy places such as motorway service areas, shopping centers, and petrol stations. Furthermore, in the long-term, the growing number of supercharger stations is set to create stability problems in Europe's power network.

E-fast charging stations equipped with mtu-battery storage. The overall system of the fast charging stations consists of the mains connection, the battery, the charging stations and a microgrid management system.
Full storage capacity The battery containers in the SYNERG-E project are around six meters long, almost three meters high and weigh up to 14 tons.

MTU battery storage systems shave peak loads induced by E-vehicle super-charging
The SYNERG-E project is to provide the solution to both these challenges: operators of super-charger stations can be sure of a reliable power supply, while transmission system operators benefit from extra electrical power. With that end in mind, Austrian electricity company Verbund Solutions and E-mobility providers Smatrics and Allego have joined forces as project partners. Between 2018 and 2019, they set up supercharger stations at three locations in Austria – in Innsbruck, Bergkirchen and Feldkirchen near Graz. Each is equipped with four charging points able to power up an E-vehicle in just a few minutes. Three further locations are planned.

The key role in the project is played by MTU-brand stationary storage batteries from Rolls-Royce which provide the much-needed buffer between the charging stations and the utility grid. “The MTU-brand EnergyPacks QM each deliver 500 kVA/ 550 kWh for performing peak shaving at times of high demand,” explained Alexander Flunk, project manager at Rolls-Royce Solutions Berlin (formally the Qinous company). “They help to avoid the high network charges that arise during peak hours and render the charging stations invulnerable to overload situations occurring on the local power grid.” MTU battery storage is central to the highly cost-effective microgrid solutions being offered by Rolls-Royce. MTU storage batteries make a positive contribution to energy sustainability and secure a reliable power supply that meets the needs of individual customers.

Surplus power for the operating reserve market
“The system as a whole basically comprises the grid connection, battery, charging points and microgrid management system. As operators, we gain from the two core functions that our super-reliable MTU-brand storage batteries perform in our project,” explained Karl Potz, head of Power Solutions at VERBUND Energy4Business GmbH. “Not only do they smooth out the fluctuations in the local power demand caused by supercharger stations, they also provide additional grid services for transmission system operators.” The surplus energy stored in the batteries is marketed by VERBUND Energy4Business as operating reserve, thereby helping to counteract stability problems in the public utility grid.

Ultra-fast charging stations for electric vehicles: pull over, fill up briefly, drive on fast - with the SYNERG-E project's fast charging stations this is everyday life for electric car drivers.
Ultra-fast charging stations for electric vehicles: pull over, fill up briefly, drive on fast - with the SYNERG-E project's fast charging stations this is everyday life for electric car drivers.
MTU EnergyPacks provide a scalable, all-in-one solution
MTU EnergyPacks are based on lithium-ion cells that have high cycle efficiency, thereby enabling an average service life of around 15 years. Their job is to store energy from the local power grid and make it available to the supercharger stations as and when required. The battery containers in the SYNERG-E project are some 6m long and 3m high and can weigh up to 14 tons. MTU EnergyPacks are generally available as scalable all-in-one solutions that boast fast power delivery and charging and a low maintenance requirement.

“With MTU EnergyPacks, simultaneous charging of up to four E-vehicles with 150 kW or two vehicles with 350 kW is now possible at our service locations without overloading the local utility grid,” explained Karl Potz from Verbund Energy4Business GmbH. A central monitoring system controls overall operation of the supercharger stations by optimizing power generation and deployment in accordance with their particular needs.

Energy and transport synergies for the whole of Europe
60% of the SYNERG-E project is financed by the 'Connecting Europe Facility', a funding instrument of the European Commission. The total project volume is 8.7 million euros. The aim of the project is to demonstrate the performance capabilities, reliability and interplay of individual components at work in the energy and transport segments. The technology and related business model are then to be implemented at a later date at other locations spread throughout Europe. “Our supercharging stations have been in continual service for over a year now and we're seeing very positive results,” reported Karl Potz from Verbund Energy4Business GmbH. “With this concept, E-vehicle drivers can look to the future with confidence.”

Pull up, tank up, and drive on – without losing time. That'll soon be the new norm for E-vehicle drivers too.

The extension of the gas fired plant is considered as an additional step towards a green future for the region and country where electricity and heat are still predominantly generated by coal-fired plants.
Libor Dolezal, CEO of C-Energy said: “We decided to install the new type of Rolls-Royce’s largest engines to enhance the plant’s thermal capacity as part of our overall strategy to reduce heat and electricity production from coal and also to expand the energy business. Given our very good experience with four engines B35:40V20, we decided to install new types providing us both higher output and efficiency in cogeneration production. It is quite exciting being the very first customer of this new type of engine, the largest one in the Rolls-Royce portfolio of medium speed engines.”
The existing 37 MWe power plant of C-Energy, located in the in Planá nad Lužnicí roughly 100 kilometers southeast of the capital Prague, was reconstructed in the beginning of 2015 with four B35:40V20 gas engines from Rolls-Royce. At this time, this was the first natural gas power plant based on medium-speed gas engines in the South Bohemian Region of the Czech Republic.
With the extension, the gas engines of the power plant will, from the end of 2019, deliver a total of 60 MWe electricity and heat for companies and homes in the nearby town of Tabor/Sezimovo Ústí. Rolls-Royce and C-energy has an agreement for a new service contract.

Rolls-Royce Power Systems business unit to restructure its brands

Illustration

- current MTU companies will now include Rolls-Royce in their names
- MTU will remain brand name for products and solutions

Aug 7 | 5 min read

Illustration

The Rolls-Royce Power Systems business unit, with its core brand MTU, will present itself more clearly in future as an integral part of the British Rolls-Royce engineering group. A new brand architecture is currently evolving, which will be visibly implemented as of autumn with the launch of the new MTU website. The new, clear brand structure will support the PS 2030 strategy of the Power Systems business unit and the global growth path. Rolls-Royce will be the corporate brand and the employer brand. Consequently, the companies within the business unit that include MTU in their names will be given a new designation. MTU, as the brand name customers are familiar with, will continue to be used to identify the company’s products and solutions. The current MTU Onsite Energy brand for decentralised power supply systems will be integrated into MTU.

One of the first visible steps to be taken will be the renaming of four operating companies, which manufacture products and solutions: MTU Friedrichshafen GmbH will thus become Rolls-Royce Solutions GmbH in autumn 2019. This will be followed by MTU America Inc., which in future will operate as Rolls-Royce Solutions America Inc. Today’s MTU Onsite Energy GmbH in Augsburg will become Rolls-Royce Solutions Augsburg GmbH and MTU Onsite Energy Systems GmbH in Ruhstorf will be renamed Rolls-Royce Solutions Ruhstorf GmbH. The remaining subsidiaries will successively be given new designations based on the above examples. The products of Bergen Engines will also be part of the new brand architecture.

“The new brand architecture will provide clarity and improve the recognition of our company and its products,” said Andreas Schell, CEO Rolls-Royce Power Systems. “Our new profile is a clear commitment to Rolls-Royce, as its second largest business unit. By the same token, Rolls-Royce is committed to our MTU brand, which is something we are proud of,” Schell added.

The new brand profile will be visible with the launch of the MTU brand’s new website in autumn of this year. Additionally, company employees will be given e-mail addresses with the domain suffix @rolls-royce.com, plus new working clothes that will emphasise the affiliation of the MTU brand with Rolls-Royce.

Almost ready to roll: 8-cylinder gas engine on the test stand

The new 8-cylinder MTU gas engine for marine applications has been humming away on Test Stand no. 146 in the new development test facility at MTU Plant 1 in Friedrichshafen since the beginning of June 2019

It is being put through its paces before the Constance Municipal Works (Stadtwerke Konstanz GmbH) will take delivery of it and a second example of these new engines at the end of the year. From 2020, the engines will be propelling a new ferry operated by Bodensee-Reederei which runs passenger services on Lake Constance. 

  • Engine technical characteristics

    The “little brother” of MTU’s already series production-ready 16V 4000 gas engine will be available with a power rating of between 750 and 1,000 kW. Starting in 2020, Rolls-Royce Power Systems and the Constance Municipal Works will be trialing two 746 kW engines in a new ferry set to ply the route between Constance and Meersburg. This will make it one of the first inland passenger vessels in Europe to be powered by high-speed pure gas engines. The fuel used is liquefied natural gas (LNG).

    “We are very much looking forward to using the MTU gas engines from our long-standing partner Rolls-Royce Power Systems in this new addition to our fleet,” said Dr. Norbert Reuter, CEO of Stadtwerke Konstanz GmbH.

    Even without exhaust gas aftertreatment, the MTU mobile gas engine is already well below the thresholds stipulated by current emission guidelines (IMO III) – indeed, particulate mass is below the verification limit, and nitrogen oxide emissions are very low. 

  • Implementation experience

    MTU unveiled its mobile gas engines for marine propulsion back in September 2016, and meanwhile prototypes have successfully racked up well in excess of more than 8,000 hours on the test stand.

MTU Africa gives mining trucks a new lease on life

MTU Africa, a subsidiary of Rolls-Royce Power Systems, has already successfully retrofitted multiple mining trucks with MTU engines and has recently added another eight projects to the list, converting three Komatsu 960-2KT and five Hitachi EH3500-AC2 mining vehicles.

These were first-time retrofits on both types of vehicle. Last December and March of this year, staff from South Africa and Zambia worked on First Quantum Minerals’ Sentinel Mine in Zambia to repower the first of three 960-2KT Komatsu trucks. In the rebuild, a competitor engine that had reached the end of its service life was replaced by a new 20-cylinder Series 4000 engine. The third project is to follow in May. 

  • Results of pilot project

    The results of the first project once again confirm the classic virtues of MTU products: “all truck operators at the mine now prefer to drive the repowered truck”, which boasts outstandingly fast response characteristics at lower engine revolutions per minute. Other quintessential MTU strengths now gained by the repowering project are greater reliability and robustness, longer maintenance intervals and lower fuel consumption. The truck fleet used at the Sentinel mine includes not only the Komatsu trucks but eight Liebherr T284 mining trucks, also powered by MTU’s 20-cylinder Series 4000 units, and two LeTourneau front-end loaders. MTU Africa has excellent credentials in mine-truck repowering, especially on Komatsu vehicles, and has in the past retrofitted Komatsu 730E, 860E-1K and 930E-4 trucks with MTU Series 4000 engines.

Each project confirms the outstanding strengths of this series, in particular in terms of excellent fuel consumption, performance, reliability and uptime, long maintenance cycles and customer service quality – all superb customer benefits.

    MTU Africa personnel were furthermore engaged by operator First Quantum in Zambia at its Kansanshi mine to replace the competitors engine of a Hitachi EH3500-AC2 mining truck with a MTU 12-cylinder Series 4000. The Kansanshi mine is the largest copper mine in Africa, and five trucks in total are to be repowered there over the next few months. The tried-and-trusted MTU 12-cylinder Series 4000 is already powering two of the Hitachi EH3500-AC3 trucks at the same mine

  • Over 800 Series 4000 retrofits worldwide

    It is always a compliment to MTU engines when they are retrofitted to mining trucks – especially when they replace other manufacturers' engines. Since the launch of the Series 2000 and Series 4000, they have been fitted to over 800 mine trucks as well as excavators, front-end loaders and surface blast hole drilling rigs worldwide, with the Series 4000 accounting for the lion's share. Each project confirms the outstanding strengths of this series, in particular in terms of excellent fuel consumption, performance, reliability and uptime, long maintenance cycles and customer service quality – all superb customer benefits. The engines used are always bang-up-to-date versions. One major driver of lower total cost of ownership is the excellent fuel consumption. “As consumption accounts for around 80 to 85% of TCO, this is a key purchasing criterion for many customers,” emphasized Robert Wagner, Senior Manager Mining /Oil & Gas in Europe, the Middle East, Africa and Russia.

Last December and March of this year, MTU Africa staff repowered 960-2KT Komatsu trucks.

    Mine trucks usually need new engines after three to five years. Rolls-Royce Power Systems supplies what it calls Repower Kits for this purpose. These are pre-assembled drive modules consisting of an engine, a generator and a radiator all mounted on a base frame. They also come with an electronic engine management and monitoring system. MTU engineers are happy and skilled to the task to tailor-made technical adjustments where necessary.

    Across the world, the most potential for repowering with the Series 4000 can be found in Russia, the US, Australia, Chile, Peru, Africa and China. As one of the latest developments in Europe, the company is currently opening up markets in Bulgaria and Serbia.

    MTU’s extensive experience in equipping dump trucks and exceptionally high qualification of the company's engineers are trusted all over the world. The largest dump truck in the world with a carrying capacity of 450 tons - the BelAZ-75710 - is equipped with two 16-cylinder diesel generators MTU DD 16V4000. This engine model has proven itself so well that BelAZ plans expansion of foreign markets in this particular configuration. Also companies are negotiating the development and implementation of innovative solutions, for example, the use of gas piston engines on BelAZ dump trucks. These trucks will be very beneficial to use in areas rich in natural gas.

Sustainable energy supply in the mining industry - Rolls-Royce Power Systems offers microgrid solutions from MTU Onsite Energy


Avatar

May 07, 2019

5 min read

Rolls-Royce Power Systems is expanding its portfolio of energy systems with the addition of microgrid solutions for mines from MTU Onsite Energy. This means that mine operators will now be offered a sustainable energy supply system that can be operated in remote regions independently of public power grids. The solutions combine renewable energy sources with a battery storage system and both diesel and gas generator sets, in addition to a central controller to ensure that the mine’s entire demand for electricity is made available in a reliable and efficient manner, and one that is friendly to the environment.
Besides diesel and gas generator sets from MTU Onsite Energy, the solutions offered by Rolls-Royce Power Systems also include battery containers combined with photovoltaic and wind power plants in microgrids. The modular designed 40-feet MTUEnergyPack is entirely new on the market. It stores electricity from any source – ready to deliver at the flick of a switch. Peak Power: 2,515 kW (DC)/ 2,475 kVA (AC); Nominal Capacity Range: 700 - 1,260 kWh 
SUSTAINABLE, EFFICIENT AND RELIABLE - ENERGY SUPPLY REQUIREMENTS IN MINES
“For mine operators, energy costs, which account on average for 15 % of the overall operating costs of mine, are a key factor,” Lars Kräft, Vice President Industrial Business at Rolls-Royce Power Systems, explains. “And with a demand for electric power of 50 to 100 MW per mine, sustainability, efficiency and the reliability of the energy supply are now becoming increasingly important in the industry. We have identified our customers’ needs and, with our microgrid systems, are now offering them a solution tailored to their specific requirements,” he adds.

RENEWABLE ENERGIES, BATTERY CONTAINERS, DIESEL AND GAS GENERATOR SETS COMBINED TO PERFECTION
Besides diesel and gas generator sets from MTU Onsite Energy, the solutions offered by Rolls-Royce Power Systems also include battery containers combined with photovoltaic and wind power plants in autonomous power grids. All the components are connected to each other via a smart energy management system, which optimises the way in which the energy is used both technically and commercially. Any excess renewable energy can be stored in the batteries and then made available whenever it is needed. At the same time, fluctuations in power generated from renewable energy sources due to weather conditions and the time of day are compensated for with reliable diesel and gas generator sets, in addition to battery storage systems. The system is thus designed to provide a stable power supply at all times – even when the demand for electric power is high and when systems are required to operate around the clock.

DECARBONISATION AND COST REDUCTION WITH RENEWABLES
Using renewable energies and the associated benefits of carbonisation means that mine operators can make considerable progress in achieving a significantly more sustainable energy supply, which also benefits their stakeholders, such as investors or communities located close to the mine. Due to the integration of renewable energies and the smart networking of all components, there is a significant cost benefit to mine operators. Fuel costs can be reduced for example, in addition to the saving of costs required for connecting mines to the power grids.

What will be in tomorrow’s tanks?

Hydrogen, methane, methanol, DME, OME, synthetic diesel – when it comes to combustible fuels we are spoilt for choice. But which of them offers the best prospects for the future? R&D specialists at MTU are currently working on a range of projects to establish which fuels are most economical and efficient and what the best engines for them will be.

The latest report from the Intergovernmental Panel on Climate Change (IPCC) reads like a final warning: This late in the day, climate targets agreed upon internationally are going to prove very difficult to achieve and they will only be achievable at all if we act with unswerving determination. And those determined efforts must include the decision to say goodbye to fossil fuels like coal, oil and natural gas because burning these resources has been a major factor in the increase of greenhouse gases in our atmosphere.

  • A future fueled by hydrogen and methane? 

    The future lies with synthetically produced fuels that offer clean and climate-neutral combustion overall. One such fuel is hydrogen that can be produced from renewable energy sources using electricity. It can either be used directly or synthesized into methane using carbon dioxide. The big advantage of hydrogen and of synthetic methane is that they produce no, or at least significantly less, polluting emissions during combustion. In addition, they can also be produced using electricity generated by wind power and photovoltaic installations. However, if not used immediately, this power has so far proved difficult to store. This explains why, on especially sunny or windy days, there is often more power available than consumers need. An alternative way of storing that energy is to use it to produce fuel – that means transforming electrical energy into energy for powering engines.

    How does electric power become fuel?
    Engine specialists have taken this line of thought a step further because methanol can be derived from methane and, as a liquid fuel, it is much easier to store. The benefits of methanol are especially obvious for marine applications. “Until now, LNG (liquefied natural gas) has been seen as a possible future fuel for ships. But LNG can only be transported and stored in high-pressure tanks or at temperatures of minus 164°. It is difficult to maintain such temperatures over longer periods of time,” explained Dr Peter Riegger, MTU Director Research & Technology. Methanol could provide an alternative because, unlike LNG, it does not require complex infrastructural storage facilities and can therefore be integrated much more easily in marine vessels.

    But methanol is not the ultimate step in the ongoing fuel development process. Methanol can be used to produce diesel alternatives such as DME and OME. These are synthetic fuels that could also be used in slightly modified diesel engines. In this context, Fischer-Tropsch synthesis processes can also be used to synthetically produce diesel fuel that fully conforms to standards.

    The main question currently facing MTU specialists is which fuel is most likely to prove most economic and most energy-efficient in the future. “If we use hydrogen to produce methane or methanol, then we lose energy in the process,” said Riegger. “Despite that, methanol could still prove to be the fuel of the future, particularly in marine applications because it is relatively simple to store and handle,” he added. However, the situation looks rather different when it comes to stationary engines for generating electricity. Here, infrastructure is by no means as important because existing natural gas grids can be extended. Consequently, for this scenario, hydrogen presents a more promising alternative.

    “I believe that we will rely on a range of different fuels in future. Sole reliance on a single fuel is not a likely option,” said Riegger. 

  • MTU projects to develop environmental friendly gas engines

    Headed jointly by MTU and the DVGW (German Technical and Scientific Association for Gas & Water) Research Unit at the Engler-Bunte Institute of the Karlsruhe Institute for Technology, the ‘MethQuest Project’ currently involves 27 partners who are working on methods of generating fuels from renewable energy sources for use in engines. One area of their activities involves MTU researchers looking at two new engine concepts for marine applications. “We are working on two different projects. One focuses on an Otto engine concept and the other involves a flexible-fuel engine concept with direct injection,” explained project leader, Dr Manuel Boog. 

    Fuel development chain
    Otto engines have been around for a long time because it is easy to burn gas in Otto engines. The problem with this concept is that the gas is never entirely combusted and uncombusted methane can escape. The phenomenon is called ‘methane slip’. “Methane is more damaging to the atmosphere than CO2. Consequently, the potential of gas engines to achieve substantial reductions in greenhouse gases is not exploited,” said Boog. One of the aims of the MethQuest Project is to develop a ‘methane oxicat’ (catalytic converter) to neutralize the negative effects of methane. The problem is that methane requires high temperatures for oxidation in the exhaust gas tract. In the engine, such temperatures are only present upstream of the turbocharger turbine. The catalytic converter therefore needs to be located here. However, this has a seriously negative influence on engine dynamics and MTU engineers are therefore working on an electrically assisted turbocharging concept that will counteract these disadvantages. 

    Gas engine with no methane slip
    The second gas-engine concept under investigation for marine applications, the flexible-fuel, direct-injection concept, involves the development of a completely new combustion process. “Here, just like in a diesel engine, the air is first compressed in the combustion chamber. The main source of energy, gas, is then introduced and a small quantity of diesel is injected at the same time to ignite the gas,” explained Boog. The advantage of this process is that the gas is almost entirely combusted and the unwanted occurrence of methane slip remains negligible. “We have already demonstrated that this combustion process works in a different, publicly sponsored project called ‘FlexDi’,” added Boog. The concept has the additional benefit that the combustion process involved also means that methanol can be used to power engines without complications. One of the challenges remaining to be solved here is the development of a suitable high-pressure gas system as the injection concept means the gas needs to be highly compressed and heated for injection.

    “We will run trials with both concepts and the pressurized gas supply system and will then decide which is the most promising for further development in the context of the drive system overall,” said Boog. Both concepts aim to produce engines that deliver comparable power and performance to diesels but with a significant reduction in environmentally negative emissions.

    Hydrogen and the combustion engine
    In the context of the ‘MethPower’ research project, MTU is also working on the development of engine concepts for stationary gas engines. “We want to establish which engine will allow us to generate electricity most efficiently,” said Project Leader Dr Michael Thoma. This project also involves the development of two engine concepts that will ultimately be compared with each other. One is a hydrogen-powered engine. “Hydrogen can be produced from superfluous electric power by electrolysis. It therefore makes sense to use it in our engines,” explained Thoma. Just as with the natural gas engine, the MethPower Project employs the combustion of hydrogen using the Otto process. A spark plug is used to ignite the hydrogen/air mixture. However, hydrogen burns much faster than natural gas. “That is a challenge we will deal with over the coming months,” declared Thoma.

    Power-to-gas
    Together with its other aims, the MethPower Project is working on the continued development of an engine that will run on natural gas and/or methane. “The MTU portfolio has included these engines for quite some time. What we are now seeking is to incorporate the engine in a system based on fuel generation and exhaust gas utilization,” said Thoma. The CO2 generated during combustion could be extracted directly from the engine exhaust and this CO2 could be used to produce new methane. “The idea is particularly interesting in the context of microgrids,” said Thoma. In this configuration, the gas engine is integrated in a network of power generators and storage devices. The network could be extended by including a ‘power-to-gas’ installation that would reduce the battery requirement. “The power-to-gas installation would work in conjunction with a gas storage vessel, like a large battery. It would use renewable electrical energy to produce methane that could be converted back to electricity if required whenever no sun or no wind is available,” explained Thoma.

    At the end of the process, R&D specialists will have to decide which concept will provide the best balance between energy generation and energy consumption and thus deliver the greatest efficiency.

    Solutions for the future
    Synthetic fuels and new engine concepts all have one thing in common – they all make a major contribution to minimizing CO2 emissions and promoting moves toward the more responsible use of energy. “That is our aim and our duty as a responsible company. We aim to develop drive solutions for the future and we commit to playing an active role in that process,” said Dr Peter Riegger in summary.

How do gas engines differ from diesel engines?


Avatar

March 15, 2019

7 min reading

Gas engines are increasingly taking the place of diesels in a range of areas including off-highway applications. Both types of engine deliver similar performance but gas engines emit less CO2 during the combustion process. 
So, what precisely are the differences between the two?
TURBOCHARGERSThe turbochargers used on diesel engines and mobile gas engines are virtually identical. They both feed the engine with the air (and, therefore, oxygen) it needs for combustion. On stationary gas units, the turbocharger has to process both the air and the entire volume of the gas/air mixture and in stationary genset applications, turbochargers are optimized to match full-load conditions because these engines generally operate at full-load.
MIXTURE COOLINGDiesel engines have charge-air coolers that cool the air heated in the compressor before it enters the combustion chamber. On gas engines, this function is performed by the mixture cooler. Depending on the application in question, the gas/air mixture is cooled in two stages to around 50 to 60°С before passing on to the combustion chamber. The thermal energy extracted during the cooling process can be decoupled from the system and fed into a heating system, for example.
FUEL MIXTUREIn diesel engines, air is sucked into the combustion chamber where it is compressed to levels that raise its temperature as high as 700°С. Injectors then introduce diesel fuel that ignites in the hot air. In stationary gas engines, the air is mixed with fuel gas before it passes through the turbocharger and mixture cooler to the combustion chamber. Mobile gas engines utilize multi-point injection systems. Here, air is routed to the cylinder and gas is introduced just before it enters the combustion chamber. This means that the volume of gas can be flexibly regulated dependidng on the power required.
IGNITIONThe most obvious difference between diesel and gas engines can be found in the ignition systems. Diesels are self-igniting engines in which high levels of compression cause the diesel/air mixture to ignite spontaneously. Like gasoline-fueled engines, gas engines use a spark generated by a spark plug to ignite the gas/air mixture (the illustration shows the spark plug connectors and cables leading to the cylinder head cover). Diesel injection systems and extraneous ignition systems on gas engines both need suitable control concepts that determine factors such as, for example, injection timing and duration (diesels) or inginition point and energy (gas).
KNOCK CONTROLDiesel fuels adhere to precise specifications and deliver highly consistent levels of quality for efficient engine set-up. However, the constituents in gaseous fuels vary and this affects combustion. For example, different gases have different methane numbers (similar to octane ratings for gasoline) that indicate the proportional mixture of an equivalent fuel consisting of methane and hydrogen. If the methane number is too low, inefficient spark ignition and other uncontrolled combustion processes can occur in the combustion chamber. These generate `engine knock` and gas engines need to be controlled to deal with the phenomenon. Stationary gas engines use vibration sensors to identify knock whilst pressure sensors do the same on mobile gas engines. Consequently, ignition timing is adjusted as an initial reaction and engine power can be reduced as a second step. In extrem cases, the engine can be shut down to prevent damage.
TROTTLE FLAPSOn both diesels and mobile gas units the formation of the fuel mixture is controlled flexibly for each ignition sequence in order to influence engine power. Stationary gas engines use a premixed gas/air mixture that remains constant and engine power is influenced by using throttle flaps to regulate the flow of the mixture. Mobile gas engines also have throttle flaps but these regulate the pressure of the mixture entering the cylinder.
