Abstract

Eine Dampfturbinenanlage (2B) mit einem Dampferzeuger (30), der eine separate Vorwärmheizfläche (82) sowie eine in den Wasser-Dampf-Kreislauf (26) einer Dampfturbine (22) geschaltete Überhitzerheizfläche (52) mit einem Dampfeinlaß (51) aufweist, soll bei einer Einspeisung von Fremddampf (F) in den Wasser-Dampf-Kreislauf (26) einen besonders hohen Gesamtwirkungsgrad aufweisen. Hierzu ist die separate Vorwärmheizfläche (82) eingangsseitig mit einer Einrichtung zur Fremddampferzeugung (80) und ausgangsseitig mit dem Dampfeinlaß (51) der Überhitzerheizfläche (52) verbunden.

Figure 00000001
A steam turbine system (2B) with a steam generator (30), which has a separate preheating surface (82) and a superheater heating surface (52) connected to the water-steam circuit (26) of a steam turbine (22) with a steam inlet (51) have a particularly high overall efficiency when foreign steam (F) is fed into the water-steam circuit (26). For this purpose, the separate preheating heating surface (82) is connected on the input side to a device for generating external steam (80) and on the output side to the steam inlet (51) of the superheater heating surface (52).
