ABSTRACT:
Apparatus and method for the partial load operation of a combined gas turbine and steam turbine plant, including a shaft being connected to the gas turbine and drivable at a given nominal speed of rotation, a first generator being connected to the shaft and electrically connectible to an electric network, a compressor being connected to the shaft and connected upstream of the gas turbine in gas flow direction, a heat exchanger having an output and a variable heat supply and being connected upstream of the gas turbine in gas flow direction, a steam generator for the steam turbine being connected downstream of the gas turbine in gas flow direction for receiving exhaust gases therefrom, a second generator being connected to the steam turbine and electrically connectible to the electric network for supplying given nominal power thereto along with the first generator, means for giving to the electric network and taking away from the network at least part of the nominal power if the shaft rotates at less than the nominal speed of rotation, and means for reducing the speed of rotation of the gas turbine for preventing a substantial drop in temperature at the output of the heat exchanger if the heat supply of the heat exchanger is reduced.
