COMBINED-CYCLE POWER GENERATION SYSTEM USING A COAL-FIRED GASIFIER

摘要

COMBINED-CYCLE POWER GENERATION SYSTEM USING A COAL-FIRED GASIFIER A integrated gasification combined cycle power generation system in which a carbonaceous material, such as coal, is gasified combusted in a gasifier to provide synthesis gas which mixes with ash produced as a result of the gasification. The mixture is cooled below the softening temperature of the ash before the gas is separated from the ash and is used to drive a gas turbine. Heat from the combustion process is removed from the gas and the ash and is used to produce steam
