摘要: A gas turbine includes a cooling air supply device for supplying compressed cooling air to moving blades, and a heat exchanger provided in the cooling air supply device for cooling the compressed cooling air. Compressed air withdrawn at an intermediate-stage portion of a compressor is used as a cooling medium for the heat exchanger. With this construction, the moving blades can be sufficiently cooled without the use of any special cooling medium.
