| MHI Receives Order for Blast-Furnace-Gas Fired GTCC For Maanshan Iron & Steel in China |
| Tokyo, February 8, 2005 - Mitsubishi Heavy Industries, Ltd. (MHI) has received an order for a blast-furnace-gas (BFG) fired gas turbine combined-cycle (GTCC) power generation plant for Maanshan Iron & Steel Company Ltd. of China. The iron and steel producer is currently expanding its plant facilities, and has opted to construct a GTCC plant in order to effectively utilize exhaust gas from its new blast furnaces to meet part of its own electricity needs. The new plant is scheduled to go on-stream in April 2007. |
The 150 MW (megawatt) GTCC plant on order will consist of an M701S (DA) gas turbine, a steam turbine, a heat recovery steam generator (HRSG) and a generator. The gas and steam turbines will be manufactured at MHI's Takasago Machinery Works, and Mitsubishi Electric Corporation will build the generator. The HRSG will be procured by the customer. Mitsubishi Corporation will handle the trade particulars. Maanshan Iron & Steel, located in Maanshan city in Anhui province, is one of China's eight major iron and steel manufacturers. The company supplies wire rods, mold steel, medium and heavy plates, and wide-flange beams. It decided to adopt a GTCC plant out of a strong desire not only to utilize BFG for power generation but also to reduce CO2 emissions. MHI has cooperated with the company from the initial planning stage. Because BFG has a lower calorie rating than natural gas - only about one-tenth in BTU (British thermal unit) parameters - stable combustion of BFG-fired gas turbines requires sophisticated technology. MHI pioneered the development of BFG GTCC technology in the 1980s and has already delivered many systems to iron and steel manufacturers at home and abroad, including some that have been in operation for more than 100,000 hours. This technological lead and track record contributed heavily to MHI's winning of the order from Maanshan Iron & Steel. With GTCC type power generation, gas and steam turbines are used in combination to generate electricity in two stages. In the first stage the gas turbine generates electricity; and in the second stage steam produced by high-temperature exhausts from the gas turbine drives the steam turbine, again producing electricity. This dual configuration enables GTCC power plants to achieve higher thermal efficiency than non-GTCC plants. Higher efficiency means that GTCC plants require less fuel relative to electricity output and emit less CO2, thus making them more environmentally friendly. Although coal-fired power generation still accounts for the largest share of China's electricity supply, the country is actively promoting introduction of GTCC power generation as a means of diversifying energy sources, enhancing generation efficiency and preserving the environment. As China's demand for steel continues to expand, local blast-furnace steel makers are consistently operating at full capacity. Last year, MHI received orders for blast-furnace GTCC power generation systems in succession from Angang Group International Trade Corporation and Jiangsu Shagang Group Company. On the strength of its superior technology and rich experience, going forward MHI intends to further strengthen its marketing activities for GTCC plants to China's iron and steel manufacturers. # # #
