Mitsubishi to Supply BF Gas Fired Power Plant to Jiangsu Shagang
Mitsubishi Heavy Industries subsidiary Mitsubishi Power has received an order to supply a 180 megawatt class gas turbine combined cycle power plant fired by blast furnace gas for Jiangsu Shagang Group, a leading Chinese steelmaker. The order, which includes an M701SDAX gas turbine as a key component, was received through Mitsubishi Power's local subsidiary. The gas turbine combined cycle plant will make effective use of gas emitted by the blast furnace operated at a Jiangsu Shagang group company, to provide part of the power needed to run its factory. Operation of the new power plant is scheduled to commence in 2023.
Amid today's global initiatives to reduce environmental impact, the steel industry, like other industries, is facing strong pressure to reduce its carbon emissions. Because blast furnace gas fired gas turbine combined cycle systems make effective use of the by-product gases emitted by steel plants, they both lighten environmental loads and contribute significantly to efficient energy usage. Blast furnace gas has a lower calorific value than natural gas, and for that reason advanced technology is required to enable its stable combustion. Mitsubishi Power first achieved its proprietary technologies in blast furnace gas fired gas fired gas turbine combined cycle power systems, including development of a dedicated combustion system, in the 1980s.
The blast furnace gas fired gas turbine combined cycle power plant will be delivered to Zhangjiagang Hongchang Plate Co Ltd in Zhangjiagang in Suzhou in Jiangsu Province. The facility will comprise a gas turbine, heat recovery steam generator, steam turbine, generator, gas compressor, and auxiliary equipment.
Mitsubishi Power will manufacture the M701SDAX gas turbine, the plant's core component, at its Takasago Works in Hyogo Prefecture, 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.
