摘要： To improve the thermal efficiency when an exhaust heat recovery type combined cycle plant having a gas turbine and a steam turbine in combination is operated at a partial load, the gas turbine exhaust is recirculated and returned to the compressor, and the combustion temperature is prevented from being lowered at the partial load. Preferably, the temperature is maintained constant. In this way, the thermal efficiency during operation at partial load can be improved.

摘要： The apparatus for cooling intake air includes a heat exchanger for transmitting the cold energy of fuel to a heat medium through an intermediate heat medium having a different property from the heat medium, a pressure controller for controlling the pressure within the heat exchanger so that a temperature of the intermediate heat medium is kept higher than a solidifying point of the heat medium, and an intake air cooling system for cooling intake air to be introduced into the gas turbine using the heat medium cold energy. The intermediate heat medium may be condensable by the cold energy of the fuel and vaporizable by the heat medium or may have a solidifying point lower than the fuel.

摘要： To provide a combined-cycle power generation plant heat exchanged effectively in an exhaust heat, the recovery boiler is increased by suppressing on reducing the swirl present in the exhaust gas of a gas turbine. That is, a plurality of stationary blades 10 are arranged on the surface of a rear inner barrel in the circumferential direction of the rear inner barrel to partition an annular channel formed between a casing and the rear inner barrel. Thereby, it is possible to uniform the flow of exhaust gas with a low pressure drop.
