Em-powering China’s steel plants

CISDI has won two valuable orders for its cost-saving ultra-high-temperature, sub-critical power generation units.

One is to be supplied to Guigang Steel in the Guangxi Province, along with a BFG holder, and another to Hongda Steel in the Shanxi Province.

The unit gives a 15 per cent increase in power generation efficiency over the high-temperature, ultra-high-pressure power generation unit.

It also reduces gas emissions to zero, helping achieve a cleaner production for the steel plant.

Both companies are pursuing boosts in green credentials, profit and competitiveness.

The project for Guigang Steel comprises a 330t/h ultra-high-temperature, sub-critical gas boiler, a 100MW intermediate primary reheating condensing turbine and a 110MW power generator.

It will achieve a zero gas emission target by eradicating 2,080 million Nm3 (BFG equivalent) of gas emission, and will generate around 800x106 kWh electricity a year, saving the steel plant around US$ 73 million on its out-sourced power spend.

The project is the first of its kind at Hongda Steel and features a 330t/h ultra-high-temperature, sub-critical gas boiler, a 100MW intermediate primary reheating, air-cooled steam turbine and a 110MW power generator.

It will reduce 2,000 million Nm3 (BFG equivalent) gas emissions, achieving zero gas emission.

Around 760x106 kWh of electricity will be generated per year, saving the steel plant US$77 million on outsourced power costs.

Both projects aim for profiting while enhancing steel plant’s competitiveness.
