Abstract
In a method operating a gas and steam turbine installation having a gas turbine which can be operated with both gas and oil, during a change of operation from gas to oil, a partial-flow mixture formed from a first partial flow of heated feedwater and from a second partial flow of comparatively cool feedwater is admixed directly with the cold condensate. Thus, this is done without a heat exchanger. To this end, the installation includes a feed line for the heated feedwater. The feed line is directed to the condensate preheater and includes an admixing point for feeding the comparatively cool feedwater.
