ラント。 In a gas and steam turbine combined power generation plant equipped with a gas turbine power generation system and a steam turbine power generation system, a reheating combustor and a waste heat steam superheater are installed in the exhaust gas pipe connecting the gas turbine and waste heat boiler of the gas turbine power generation system. This waste heat steam superheater is connected to the superheated steam pipe between the superheater and the steam turbine of the steam turbine power generation system through superheated steam piping, and the connection between the reheating combustor and the waste heat boiler is An exhaust gas switching damper is provided in the exhaust gas pipe between, and the superheated steam pipe 4 of the steam turbine power generation system to which the superheated steam pipe is connected is connected to the process steam pipe of the waste heat boiler of the gas turbine power generation system, respectively. A combined power generation plant using a gas and steam turbine, comprising a valve, and selectively opening and closing the exhaust gas switching damper and the steam switching valve, thereby increasing the overall thermal efficiency of the power generation plant.
