The cooling of a gas turbine is a critical problem and will consume a considerable quantity of compressed air at the temperature ordinarily available. To improve the cooling properties, a portion of the air delivered by the compressor is divided off and is conveyed to an expansion member, where it is further divided into a hot and a cold fraction. This cold fraction, which can have a temperature well below the freezing point, is used, preferably mixed with air delivered directly from the compressor, for cooling the turbine inlet means.
A gas turbine power plant comprising at least one compressor, at least one combustion chamber and at least one turbine and further including means for dividing off a portion of the compressed air delivered by the compressor for cooling the turbine, the improvement of an expansion member including means arranged to divide a supply fluid into a hot fraction and a cold fraction, means for conveying said divided-off portion of compressed air to said expansion member, further means for conveying at least part of said cold fraction to the inlet means of the sa...
