Abstract:
A combined cycle electric power generating plant includes gas and steam turbines and a heat recovery steam generator recovering the heat in the exhaust gases exited from the gas turbine and for using the recovered heat to produce and supply steam to the steam turbine. The gas turbine includes a plurality of variably set guide vanes whose position may be set to determine the inlet flow to the gas turbine. Guide vane control apparatus is provided to limit the inlet guide vane position as a function of gas turbine compressor inlet temperature in accordance with a desired gas turbine exhaust flow, and to match the gas turbine exhaust flow to the steam requirements of the steam generator as in turn determined by the load placed upon its steam turbine. In addition, an afterburner is provided to supplementally heat the exhaust gas turbine gases before they are directed to the steam generator. During the startup, the afterburners are operated to supply supplemental heating to the gas turbine exhaust gases supplied to the steam generator whereby the temperature of the steam passed to the steam turbine is maintained at a minimum level.
