CARBON DIOXIDE RECOVERY TYPE GASIFICATION POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a CO2recovery type gasification power generation system including a gasification installation and a closed-cycle gas turbine installation and achieving high efficiency, by achieving a simple system structure. SOLUTION: This CO2recovery type gasification power generation system includes: the gasification installation provided with a means for charging CO2to the inside of a gasification furnace 31 producing gasification gas by reaction of carbon fuel with oxygen; and the closed-cycle gas turbine installation using the gasification gas delivered from the gasification installation as fuel. The closed-cycle gas turbine installation is provided with: a compressor 2 compressing gas mainly composed of CO2and moisture; a humidification device 7 humidifying the gas compressed by the compressor; a combustor 4 burning the gas humidified by the humidification device 7 and the gasification gas delivered from the gasification installation; a turbine 1 expanding combustion gas produced by the combustor 4 to thereby take out power energy; and a regenerative heat exchanger 12 heating the gas humidified by the humidification device 7 by exhaust gas from the turbine 1.
