Caterpillar Inc. announces the introduction of the C175-16 diesel package generator set for standby, prime and continuous applications. The generator set is available worldwide in 60 Hz packages with ratings up to 3.1 MW and 50 Hz packages with ratings up to 3.1 MVA. The Cat® C175-16 generator set package was designed to offer a larger unit rating, higher power density, lower emissions and reduced installation costs. Meeting U.S. EPA Tier 2 requirements, the new generator set addresses current and future needs of the worldwide electric power industry.
Unveiled in 2006, C175 diesel generator sets have successfully completed rigorous field reliability demonstrations in real-world applications spanning the globe.
The C175 has been used for applications ranging from distributed generation to prime power for remote communities, industrial processing plants and rock crushing applications.
Five key engine systems comprise the Cat C175-16: fuel system, electronics and controls, air system, cooling system and lubrication system. Engineers incorporated significant input from Voice of Customer (VOC) market research into the design of the systems, allowing Caterpillar to deliver a world-class engine to customers seeking standby and prime power application solutions.
The C175-16's fuel system utilizes a high pressure fuel pump and control valve that deliver multiple precise injections within a single combustion event. This results in lower emissions, improved performance and reduced fuel consumption. Driven by the ADEM™ A4 controller, the C175-16 engine management system provides superior performance, even in the most demanding environments.
The air system delivers cooler combustion air at the cross-flow cylinder heads, allowing for higher power density and emission reduction. A new generation of turbochargers was designed for the C175, providing a 5 percent efficiency boost and longer life when compared to traditional turbochargers.
A newly designed cooling system cools only the parts of the engine that require cooling, resulting in increased efficiency and lower heat rejection. This method of temperature control allows customers to reduce overall operating costs by using smaller radiators.
The lubrication system utilizes Cat® Advanced High Efficiency Oil Filters which provide a higher level of filtration efficiency while maintaining Caterpillar's superior capacity.

Siemens Energy is to adapt its proprietary process for carbon dioxide capture to the special conditions prevalent in and mode of operation of combined-cycle power plants for the Norwegian utility Statkraft. The project kicked off in January 2009 and is scheduled to be completed within two years. This technology will then be available for industrial-scale applications.
Fossil energy will remain the cornerstone of power generation for the foreseeable future. The task to be performed here is to meet increasing energy demand while simultaneously protecting our environment.
Combined cycle power plants are in great demand throughout the world due to their high efficiency and low environmental impact. They do, however, impose stringent requirements on the process used for CO2 capture. Their flue gas has a lower CO2 concentration than that in coal-fired plants while simultaneously exhibiting a high oxygen content, conditions which have a very negative impact on known solvents.
The technology for CO2 capture from the flue gas of power plants is an important feature of the Siemens environmental portfolio. In 2008, revenue from the products and solutions of Siemens environmental portfolio was nearly EUR 19 billion, which is equivalent to around a quarter of Siemens total revenue.

Mitsubishi Heavy Industries, Ltd. (MHI) has completed development of the "J-series" gas turbine, featuring the world's largest power generation capacity and highest thermal efficiency. The unit is designed to operate at a very high temperature near 1,600 degrees Celsius (°C) at the turbine inlet. The company has also launched activities towards the turbine's commercial production.
The 60 hertz J-series gas turbine achieves a rated power output of about 320 megawatts (MW) (ISO basis) and 460 MW combined-cycle power generation – also the world's largest. In gas turbine combined-cycle (GTCC) applications, high-temperature exhaust gas from the gas turbine is used to generate power by a steam turbine. The company is aiming to achieve over 60% thermal efficiency in GTCC applications, the world's highest level. The company will soon begin marketing, with delivery to commence in 2011.
J-series GTCC power generation will achieve CO2 emissions approximately 50% lower than with conventional coal-fired power generation (comparison with MHI's power plants). In this way, the newly developed turbine is expected to contribute significantly to worldwide efforts to reduce global warming.

The power plant will provide electricity and heat for administrative-commercial complex of the insurance company in Moscow. The station consists of three Caterpillar gas engine power units – two G3512 rated at 770 kW each and one G3508 power unit with the capacity 510 kW. The supplier of the power equipment is Zeppelin Russland Ltd. The project is realized under the turnkey by Ecogas Ltd.
For stable heat supply in cold weather two Logano SK725 hot-water boilers with the capacity 1600 and 1320 kW by Buderus were installed. Two gas control units are used to decrease and regulate gas pressure in the power unit. The commissioning is planned for the end of the year.
