Abstract
A device is for preheating combustibles in combined gas and steam turbine installations. The device includes at least one steam generator for heating, evaporating and superheating feed water, which has a feed water preheater, an evaporator and a superheater. At least part of the heated feed water is used for preheating combustibles in a combustible preheater, which can be supplied with feed water of a predetermined temperature by a feed water supply line. Once the combustible has been heated, the cooled feed water can be drained using a feed water drain line. The device is configured so that it can be used in different gas turbine installations and its heating capacity can be rapidly and cost-effectively adapted to predetermined combustible preheating requirements. To achieve this, the combustible is preheated in stages, which can be activated individually as required and through which the combustible can successively pass.
