ント。[Scope of Claim for Utility Model Registration] (1) An exhaust heat recovery boiler that generates steam by receiving exhaust heat sent out from a gas turbine, and a steam turbine that is rotationally driven by receiving the steam sent from the exhaust heat recovery boiler. The exhaust heat recovery boiler is equipped with a low-pressure economizer, a low-pressure boiler, a high-pressure economizer, a high-pressure boiler, and a high-pressure superheater arranged in this order from its inlet, and furthermore, the outlet of the low-pressure economizer is equipped with a high-pressure pump. In a combined cycle plant that adopts a configuration in which an intervening branch pipe is bypassed, one of the branch pipes is connected to the inlet of the low-pressure economizer, and the other is connected separately to both the high-pressure economizer and the low-pressure boiler. . A combined cycle plant, characterized in that the outlet of the high-pressure economizer bypasses a branch pipe, and the branch pipe after the bypass is connected to the inlet of the low-pressure economizer via a flow control valve. (2) The flow rate control valve is characterized in that its opening and closing are adjusted by at least one signal among the inlet water supply temperature signal of the low-pressure energy saver, the water supply flow rate signal of the high-pressure pump, and the water supply flow rate signal of the high-pressure energy saver. A combined cycle plant according to claim 1 of the utility model registration claim.
