发明名称 Gas turbine for combined cycle power plant with steam cooling of stationary blades
摘要 A combined cycle power plant has a gas turbine and an exhaust heat recovery boiler to which exhaust gas from the gas turbine is supplied. The exhaust heat recovery boiler is configured to generate steam for cooling. The combined cycle power plant has several elements: a cooling steam supply pipe; a cooling steam recovery pipe; and a cooling steam connecting pipe. The cooling steam connecting pipe has a cross-sectional area larger than cross-sectional areas of the cooling steam supply pipe and the cooling steam recovery pipe so that a pressure drop thereacross, as a whole, is small.
