Stator blades and rotor blades are cooled by discharge air discharged from an air compressor coupled directly with gas turbine. A signal of the compressor discharge pressure and a signal of turbine exhaust gas temperature are obtained, and cooling air flow is controlled based on these signals.
A cooling air flow controlling apparatus for a gas turbine comprising: an air compressor coupled directly with a gas turbine, a passage for introducing a portion of air discharged from said air compressor as cooling air flow into a hot gas section of said gas turbine, and a control valve for controlling cooling air flow disposed in said passage, a first means for detecting a discharge air pressure from said air compressor and for outputting a discharge air pressure signal, a second means for detecting an exhaust gas temperature of said gas turbine and fo...
