IGCC plant using the heat recovery in compressed air process

摘要

The invention gasification means for producing a gas using a fuel; A gas turbine operated by burning gas; A boiler for producing steam by vaporizing the first fluid with heat of the exhaust gas introduced from the gas turbine; And a steam turbine connected to the boiler to operate as a steam; Air separation means for separating oxygen from the air by means of cryogenic air separation and for supplying oxygen to the gasification means; Improving the power generation efficiency by implementing a gasification combined cycle plant using the waste heat of the air compression process comprising a; and a waste heat recovery means for transferring the waste heat generated during the process of compressing air in the air separation means to the combined cycle power generation means And eco-friendly electric energy production is possible.
