Abstract
A combined cycle gas turbine plant and a corresponding method for operating such a combined cycle gas turbine plant, in which, during load operation of the combined cycle gas turbine plant, a water mass flow which is supplied according to the forced-flow principle to a waste heat steam generator is adjusted such that the evaporator heating surface of the medium pressure stage is oversupplied and thus a defined amount of excess water, which is heated in the evaporator heating surface but not vaporized, is discharged via the water-steam separator to a heat exchanger circuit for preheating fuel for the gas turbine.
