Abstract
A method and apparatus for a combined turbine installation includes a gas turbine group with a compressor having a water cooler, a combustion chamber and a gas turbine, and having a steam turbine installation with a waste heat boiler heated by the exhaust gas from the gas turbine. The waste heat boiler includes an evaporator, drum, enconomizer and superheater, a steam turbine downstream of the waste heat boiler and a combined feed water tank/flash evaporator unit. The feed water tank/flash evaporator is supplied with condensate from a condenser fitted downstream of the steam turbine. Cooling water heated by the compressed air is evaporated in at least one state and the steam produced is fed to the waste heat boiler for further heating, or directly to the steam turbine. In addition, the unevaporated residual water is fed to the feed water tank/flash evaporation unit, and after mixing with the condensate from the steam turbine, is supplied to the compressor cooler.
