Abstract:
1. A combined cycle plant including a compressor for compressing intake air taken in via an air intake duct, a combustor for burning compressed air compressed by the compressor and a fuel gas, a gas turbine driven by a combustion gas obtained by combustion in the combustor, a waste heat boiler for recovering heat in an exhaust gas discharged from the gas turbine to generate steam, a steam turbine driven by steam generated by the waste heat boiler, and a condenser for condensing exhaust steam discharged from the steam turbine into water, a heat exchanger disposed in the air intake duct; and a heating medium flow-through structure for branching part of steam, which has been generated in a superheater of the waste heat boiler and is sent to the steam turbine, flowing the part of the steam through the heat exchanger, and also returning water, which has been discharged from the heat exchanger, to the condenser.
