Siemens is to continue the expansion of local value creation in growth markets. The company is to expand its steam turbine production in the state of Gujarat for approximately EUR40 million. A new production facility with a surface area of 14,000 square meters is planned. Production capacity for high-efficiency industrial steam turbines will thus triple by 2010. In addition to the Indian market, the turbines will also be exported throughout Asia and Africa, where they will contribute to providing extensive power supply.
Industrial turbines with ratings up to 45 megawatts have to date been produced in Vadodara. The location is part of Siemens manufacturing network for industrial turbines, which is managed from Görlitz. Only recently the company inaugurated a new production facility in Görlitz to be able to better meet the demand for medium-size steam turbines. The additional production capacity in Vadodara will provide the basis for even better serving the markets in Asia and Africa. There are currently still high energy deficits in many emerging countries during peak load periods. However, adequate energy supply is a fundamental prerequisite for moving economic and social development forward in these countries.
High-efficiency industrial steam turbines are an important feature of Siemens environmental portfolio, with which the company posted revenue totaling almost EUR19 billion in fiscal 2008. That is equivalent to around a quarter of the company’s total revenue and makes Siemens the world’s leading green infrastructure provider. Industrial steam turbines are deployed above all in cogeneration plants, combined heat and power plants, and small combined cycle plants, which are among the most efficient forms of power and heat generation. Small and medium-size steam turbines are also deployed, for example, in sugar and pulp mills or in the chemical industry to make even better use of process steam.

To help meet growing energy and environmental needs in the Iberian region, DETISA, an energy supplier owned by major Spanish oil company CEPSA, has selected GE Energy’s gas turbine technology for a new cogeneration project in San Roque, Cádiz, Spain.
GE will supply a Frame 6B gas turbine-generator for the Lubrisur Cogeneration Plant, which will help to meet the increasing energy requirements of the Gibraltar-San Roque refinery, with excess electricity to be sold to the Spanish grid. The plant has a capacity of 42 megawatts of power and also will produce steam to be used for refinery processes.
Burning natural gas, the Frame 6B gas turbine will employ a dry low NOx system that will meet the region’s strict environmental regulations.
Cogeneration is a growing trend in Spain, where the government is pushing for energy savings, reduced grid losses and reduced greenhouse emissions to meet the standards of the Kyoto Protocol on Climate Change.
The GE Frame 6B is one of the most versatile and widely used gas turbines ever manufactured. More than 1,100 of these units are in service or on order worldwide and have accumulated more than 60 million operating hours. Close to 30% of all 6Bs in operation are being used for cogeneration, located in countries on six continents.
Commercial operation of the Lubrisur project is scheduled to begin by the end of 2010.
MAN Diesel, in collaboration with wind turbine manufacturer Enercon and planning and consulting firm Econcern, is building the world’s largest wind/ diesel hybrid power plant on the Caribbean island of Bonaire. The plant comprises a wind park with twelve wind turbines and a (bio-)diesel power plant that will produce electrical power with five MAN diesel engines of type 9L27/38. The hybrid power plant will function as an independent base load power plant from the end of 2009 onwards, supplying the entire island with a total of 25 MW of eco-friendly energy. The value of the order for MAN Diesel is over Euro 15 million. The customer is Water en Energie Bedrijf Bonaire (WEB), the state-run energy provider in the Dutch Antilles.
The wind park will be the primary source of electricity generation. During calm periods, tropical storms or peaks in demand, the engines in the diesel power plant will also kick in quickly to ensure a constant and reliable supply of power to the population. Compared to conventional power plants, such as the large steam turbine systems used to generate electricity, MAN Diesel engines have the advantage that they require only a very short start-up time and therefore are available virtually at the press of a button. This flexibility makes them the ideal assembly for wind hybrid power plants. Intelligent control electronics ensure that the MAN Diesel power plant is able to even out the inconstant electricity generation from wind energy and the fluctuations in demand. The extremely high efficiency of diesel engines also ensures the maximum possible yield from the fuel used. These – according to the plans – will be switched over within the next three years entirely to bio-diesel, which is to be obtained from seaweed. The wind/diesel hybrid power plant will then sustainably provide the entire island with CO2-neutral electricity and thus save around 70,000 tonnes of the greenhouse gas a year compared to the current power plant, which runs on fossil fuels.
The specialist for propulsion and power solutions Tognum has recently been awarded a strategically important onsite energy contract by international construction firm Orascom Construction Industries. Tognum is to furnish a new airport tower at Cairo International Airport – the airport with the second highest passenger numbers on the African continent – with two emergency power supply gensets.
These MTU Onsite Energy gensets are designed to supply the new tower, which is scheduled to start operating in June, with emergency power whenever outages occur.
The emergency power supply gensets equipped with 12V 4000 G63 engines deliver a total of 4,000 kVA electrical power. Should the power supply in the tower fail, the MTU Onsite Energy gensets ensure air traffic control continues as required.
Strict regulations apply to the technical requirements imposed on the operation of gensets for airport control towers. These affect, in particular, the stability of both voltage and frequency when activating a variety of consumer units, e.g. elevators, lighting or IT systems. Also, sound insulation is used in the intake and exhaust air areas in order to keep well below the maximum permitted noise emission limits.
The power unit commissioned by Energotechmontazh, MPNU designed on the base of C-30 microturbine by Capstone Turbine Corporation was put in operation at the beginning of the year as part of the power complex at the industrial site.
In addition to gas turbine power unit the power complex is equipped with GFL-200 Vacotin Heater vacuum boiler by Takuma Boiler Company (Japan) with the capacity of 300 kW and 500 kW NPR-500 hot-water boiler manufactured by Garioni Naval (Italy).
Mitsubishi Heavy Industries, Ltd. (MHI) and Southern Company, a major U.S. electric utility, will jointly demonstrate a plant to test technology enabling recovery of between 100,000 and 150,000 metric tons of carbon dioxide (CO2) per year from flue-gas emissions from a coal-fired power generation plant.
The demonstration, involving the equivalent of emissions from 25 megawatts of the plant's generating capacity, is scheduled to begin operating by the first quarter of 2011. While the technology to recover and compress CO2 from natural gas-fired flue gas has already been applied commercially, the planned development and demonstration testing of the plant in the application of CO2 recovery from flue gas of coal-fired generation plant, which contains more impurities, will be on a scale unprecedented anywhere in the world.
Based on the test results, MHI will pursue the CO2 recovery/compression technology needed for commercial-scale carbon capture.
The host site for the carbon capture project is Plant Barry, a unit of Southern Company subsidiary Alabama Power. The MHI carbon capture technology will be installed on an existing unit of the plant, with the CO2 captured in the demonstration transported by pipeline and injected underground at a site away from the plant grounds. The U.S. Department of Energy's (DOE) Southeast Regional Carbon Sequestration Partnership will be responsible for the transport and sequestration.
Specifically, MHI will be responsible for plant engineering, equipment supply, and provision of technical support during the demonstration phase.
The CO2 recovery and compression process consists of various facilities, including those for high-performance pre-processing desulfurization, flue gas CO2 recovery, recovered CO2 compression and utility.
MHI's CO2 recovery technology is KM-CDR Process™ ("The Process") that uses the company's proprietary KS-1 solvent for CO2 absorption and desorption, which MHI and the Kansai Electric Power Co., Inc. jointly developed. The Process requires considerably lower energy consumption than other technologies. Through the demonstration of the efficiency of The Process for the level of impurities contained in coal-fired flue gas in order to confirm the technology which is commercially viable.
The Business Unit Turbocharger at MAN Diesel has recently announced that its complete ranges of TCA axial and TCR radial turbochargers are available for both two and four-stroke engines complying with IMO Tier II emissions legislation. Indeed, the Augsburg-based engine and turbocharger specialist stresses, the requirements of IMO Tier II engines were designed into the TCA and TCR turbochargers from the first.
Importantly, to eliminate additional work for engine builders, the new, higher performance IMO Tier II turbocharger versions from MAN Diesel retain the same external and connection dimensions as versions for IMO Tier I compliant engines. In this way, no changes are needed to the existing turbocharger mounting arrangement when upgrading an ongoing engine series to IMO Tier II compliance. The major change with the IMO Tier II versions of TCA and TCR turbochargers has been to increase pressure ratios to enable Miller cycles of varying intensity as a means of substantially reducing the formation of oxides of nitrogen (NOx). On four-stroke engines this involves closing the inlet valve early to allow the incoming air to expand and cool and thus eliminate the combustion temperature peaks responsible for the majority of NOx formation. On low-speed, two-stroke engines the same effect is achieved by reduction of compression volume, increased scavenging air pressure and late closing of the exhaust valve, in some cases combined with optimisation of the fuel system. Higher pressure turbocharging ensures that an equivalent amount of air enters the cylinder, thus leaving engine power, torque and response unaffected.
For two-stroke engine applications MAN Diesel reports that the necessary increase in pressure ratio is achieved exclusively via minor changes to the internal flow components of the turbochargers. On the four-stroke side, the new high-pressure turbocharger versions feature a revised design of compressor wheel with enhanced performance, as well as a number of further internal revisions.
