COMBINED CYCLE GAS TURBINE PLANT COMPRISING A WASTE HEAT STEAM GENERATOR AND FUEL PREHEATING STEP

摘要

The present invention relates to a combined-cycle power plant and a corresponding method of operation of a combined-cycle power plant of this type wherein the water mass flow rate supplied to the waste heat steam generator constructed in accordance with the forced- Is supplied to the evaporator heating surface (6) of the evaporator heating surface (6) so that a prescribed amount of excess water heated in the evaporator heating surface (6), but not evaporated, passes through the water-vapor separator (11) Heat exchanger circuit.
