Mitsubishi Power will manufacture the M701SDAX gas turbine, the plant's core component, at its Takasago Works in Hyogo Prefecture in Japan, and also supply related and auxiliary equipment. The steam turbine and generator will be provided by Dongfang Electric Group, a Chinese manufacturer of heavy electric machinery with which Mitsubishi Power has a cooperative relationship. The operation of the new power plant is scheduled to start in 2023.
To date, Mitsubishi Power has supplied Jiangsu Shagang with four BGF CCGT power plants, starting with the first facility inaugurated in 2005.
Blast furnace gases have low calorific value, being composed mainly of carbon dioxide and nitrogen with only about 15% carbon monoxide and a 2-4% hydrogen providing the heat.
