CISDI’s gas power generation expertise moves into supercritical with project for Lianyuan Steel

CISDI is to build a 150-megawatt supercritical excess gas power generation plant at Lianyuan Steel in China’s Hunan Province. 

CISDI’s vast experience in gas power generation encompasses ultra-high-pressure, ultra-high-temperature and ultra-high-pressure, sub-critical, and super-critical.

The project for Lianyuan will be CISDI’s first venture into supercritcal. The design will feature the highest parameters and highest efficiency in the world. 

The plant will comprise of the following main units: 

·  a 502-tonne-per-hour supercritical primary reheating gas boiler

·  a 150MW condensing steam turbine

·  a 180MW power generator’s auxiliary facility.

State-of-the-art supercritical gas power generation tech will be applied, which will result in a 10 per cent increase in efficiency, compared with subcritical tech. 

After the project goes into operation, a generating capacity of 13x10⁸ kilowatt-hour is envisaged, effecting a direct economic benefit of around US$ 119 million. 

With a higher standard of gas resource-efficiency, Lianyuan Steel will become a greener steel producer.
