Abstract
A land based gas turbine apparatus includes an integral compressor; a turbine component having a combustor to which air from the integral compressor and fuel are supplied; and a generator operatively connected to the turbine for generating electricity; wherein hot gas path component parts in the turbine component are cooled entirely or at least partially by cooling air or other cooling media supplied by an external compressor. A method is also provided which includes the steps of supplying compressed air to the combustor from the integral compressor; and supplying at least a portion of the cooling air or other cooling media to the hot gas path parts in the turbine component from an external compressor.
Claims4
A method of insuring peak power capability for a gas turbine power plant including an integral compressor, a turbine component, a combustor and a generator, wherein hot gas path parts in the turbine component are cooled by cooling air, the method comprising:
- a) supplying compressed air to said combustor from said integral compressor;
- b) supplying at least a portion of the cooling air or other cooling media to said hot gas path parts in the turbine component from an external compressor;
- and
- c) augmenting supply of compressed air to the combustor with compressed air from said external compressor.
