Condensate recirculation

A combined-cycle turbine plant, comprising:

• at least one gas turbine,
• a steam turbine,
• a waste heat steam generator, wherein the waste heat steam generator comprises a condensate preheater into which a condensate line leads and a feedwater preheater connected upstream of the condensate preheater in a direction of flow of a gas turbine waste gas, wherein upstream of which feedwater preheater a feedwater pump is connected,
• wherein the feedwater preheater is connected to a further stage of the waste heat steam generator that is disposed upstream of the feedwater preheater in the direction of flow of the gas turbine waste gas via a first circuit, and is connected to a fuel preheating unit for the at least one gas turbine via a second circuit that splits off the first circuit from a point between the feedwater preheater and the further stage, and
• a third circuit for cooled feedwater that leads from the fuel preheating unit into a pump medium inlet of a jet pump that further comprises:
• a suction medium inlet connected to an outlet of the condensate preheater;
• and an outlet connected to the condensate line, wherein in the third circuit the cooled feedwater is not subjectable to throttling.
