摘要： A combined cycle power plant comprises a gas turbine system and a steam cycle system having a steam turbine to be driven by the steam generated by the waste heat of the exhaust gas of the gas turbine system, wherein the steam from the steam cycle system flows through a gas turbine cooling system of the gas turbine to cool the gas turbine blades and other elements of the gas turbine system to be cooled and the waste heat of the gas turbine system is effectively collected. The gas turbine cooling system is supplied selectively with bleed air from the compressor of the gas turbine or the steam provided from another steam cycle system in order to ensure a sufficient coolant supply at the time of starting and stopping the plant and during the operation with a partial load.

摘要： A cooling flow passage assembly consisting of pressure side cooling flow passages extending in a span direction and suction side cooling flow passages extending in the span direction and serially connected to the pressure side cooling flow passages is formed in a turbine blade. A cooling medium flows through the pressure side cooling flow passages in the direction toward the tip portion and through the suction side cooling flow passages in the direction toward the root. Cooling effect is improved by a Coriolis force. The number of the suction side cooling flow passages is larger than the number of the pressure side cooling flow passages. At least one of the suction side cooling flow passages forms at least one most downstream cooling flow passage. The cooling medium flows through the most downstream cooling flow passage and is exhausted outside of the turbine blade through nozzles, whereby the flow of the cooling medium through the most downstream cooling flow passage is speeded up.
