PURPOSE:To aim at an efficiency improvement, by heating discharge compressed air with waste gas out of a combustion furnace of a pyrolytic gasifier, while leading it into a duct burner together with pressure combustible gas out of a gasifier furnace for a complete combustion. CONSTITUTION:Waste gas out of a combustion furnace 36 of a pyrolytic gasifier 35 gasifying wood solid fuel is led into an air heater 41 and heats discharge compressed air as specified. And, combustible gas out of a gasifier furnace 38 is pressurized with a gas compressor 43. The heated compressed gas and the pressurized combustible gas both are led into a duct burner 44 and burned and fed to a gas turbine 32. With this constitution, since such combustion gas as being sufficiently raised in temperature is secured, efficiency is well improvable.
