Abstract

Ein Dampf turbinensystem für ein Kraftwerk weist eine Dampfturbine, die an ihrem Frischdampf eintritt ein Frischdampfregelventil aufweist und einen Anzapfdampfaustritt hat, und eine Frischdampfumgehungsleitung mit einem Drosselventil auf, die am Eintritt des Frischdampfregelventils sowie an dem Dampfaustritt zum Leiten von mit dem Drosselventil gedrosselten Frischdampf von stromauf des Frischdampfventils zu dem Anzapfdampfaustritt angeschlossen ist, wobei die Dampfturbine mit dem Frischdampfregelventil und die Frischdampfumgehungsleitung mit dem Drosselventil derart ausgelegt sind, dass die Dampfturbine sowohl im Nennbetriebszustand bei 100% Frischdampfmassenstrom als auch in einem Sonderbetriebszustand bei über 100% Frischdampfmassenstrom jeweils mit voll geöffneten Frischdampfregelventil fahrbar ist, wobei überschüssiger Frischdampfmassenstrom gegenüber dem Nennbetriebszustand an den Eintritt des Frischdampfregelventils via der Frischampfumgehungsleiung an der Dampfturbine vorbeileitbar ist oder bei 100% Frischdampfmassenstrom ein Absenken des statischen Drucks des Frischdampfs durch Vorbeileiten eines vorherbestimmten Anteils des Frischdampfmassenstroms via der Frischdampf Umgehungsleitung erreichbar ist. Ein Kraftwerk mit dem Dampfturbinensystem weist zum Überhitzen des Frischdampfes einen Zwischenüberhitzer auf, dem der Anzapfdampf zuführbar ist.
