<p>A land based gas turbine apparatus includes an integral compressor (110, 210); a turbine (114, 214) having a combustor (112, 212) to which air from the integral compressor and fuel are supplied; and a generator (132) operatively connected to the turbine for generating electricity; wherein hot gas path component parts in the turbine are cooled entirely or at least partially by cooling air supplied by an external compressor (136, 236). A method is also provided which includes the steps of supplying at least a portion of the cooling air to the hot gas path parts in the turbine (114, 214) from the integral compressor (110, 210); and supplying a remaining portion of the cooling air from an external compressor (136, 236). <IMAGE></p> |
