for blast-furnace-gas (BFG) fired gas turbine combined-cycle (GTCC) power generation plants from China and Korea. The two purchases will contribute to better air quality in the two countries.
Qian’an Iron and Steel Works, part of Chinese steelmaker Shougang Group, has ordered a 150 megawatt (MW) plant while Korea’s largest independent power producer, POSCO Power Corp, has signed on for two similar plants with a combined output of 284 MW.
MHI said it will deliver the power plant to Qian’an Iron and Steel Works’ site in Hebei Province 150 km east of Beijing in May 2009.
The equipment for the two 142 MW power plants in Korea are scheduled for delivery in 2009 and 2010. The Korean order represents the country’s second order for a low calorie heating value furnace-gas-fired GTCC plant, following a FINEX gas-fired plant ordered for POSCO Pohang Works in 2005.
Qian’an Iron and Steel Works aims to use the low-calorie by-product gas from its blast furnace to meet part of its own electricity needs at the steel plant. The GTCC plant will incorporate an M701S (DA) gas turbine, a steam turbine, a generator and other equipment. MHI will design and manufacture the gas and steam turbines while Mitsubishi Electric Corp will supply the generator.
With the approach of the Olympic Games, the Beijing-based Shougang Group stopped operating the blast furnaces in the capital city.
The company is currently constructing large-scale furnaces that incorporate advanced environmental protection measures in Hebei. The introduction of the BFG-GTCC plant is part of that environment protection programme.
POSCO Power is also introducing the BFG-GTCC at its Gwangyang site in Korea’s southern coast to improve energy efficiency and reduce pollution.
The two power plants will each consist of an M501S (DA) gas turbine, a steam turbine, a generator and other equipment. The order was placed to MHI through POSCO Engineering & Construction Co Ltd (POSCO E&C) of Pohang, which is a major general construction company in Korea and the engineering, procurement and construction (EPC) contractor for this BFG-GTCC project.
Similar to the Chinese order, MHI will design and manufacture the gas and steam turbines while Mitsubishi Electric Corp will supply the generators.
