ADVANCED HYBRID COAL GASIFICATION CYCLE UTILIZING A RECYCLED WORKING FLUID

摘要

Electricity generation system has hybrid gasification cycle (10), and wherein CO2 is recycled to gasifier (12) as gasification reactant and working fluid. The electricity generation system includes source fresh, pure oxygen (20), gasifier, particle separator (16) setting is connect in flowing with gasifier, the outlet of flowing interconnecting piece and gas turbine is arranged in syngas combustion device (48), combustion gas turbine (50), gas compressor system (36), the stream of the compressed exhaust gas of one first part of exhaust emissions gasoline (34) of these a series of compressions is directed to gasifier, it is controlled in the temperature of gasifier, to provide CO2 and steam gasification, the demand of fresh, pure oxygen is reduced wherein.
