Abstract

Method for operating a gas and steam turbine system without a feedwater tank, wherein heat contained in a pressure-relieved operating fluid of a gas turbine is utilized to produce steam for a steam turbine, includes the steps of preheating condensate flowing in a water-steam loop of the steam turbine; returning a first quantitative fraction of the preheated condensate in a loop for further preheating; and evaporating a second quantitative fraction of the preheated condensate; and a device for performing the foregoing method.
