Kind Code:
A
Abstract:
To provide a gas turbine cooling device having improved cycle efficiency by using compressor bleed air matching to each stage for cooling a turbine with reduced loss, instead of unnecessarily using compressor discharge air.
The gas turbine having turbine stationary blades 4-7 to be cooled by the discharge air and the intermediate stage bleed air from an air compressor 1 comprises cooling systems A, B for cooling turbine moving blades 13, 14 by supplying the intermediate stage bleed air from the air compressor 1 through the turbine stationary blades 5, 6 thereto.
