Abstract

Dem Sperrdampfsystem einer Dampfturbine muss in manschen Betriebszuständen Zusatz-Sperrdampf zugeführt werden. Die Zufuhr von Zusatz-Sperrdampf aus der Frischdampfleitung ist mit erheblichen Problemen behaftet. Erfindungsgemäss wird daher das Sperrdampfsystem (9) über eine Anspeiseleitung (7) einer Entnahmestelle des Überhitzers des Kessels verbunden, so, dass die Temperatur des Zusatz-Sperrdampfes weit unterhalb der Frischdampfdaten liegt, und insbesondere mit der Materialtemperatur im Bereich der Hochdruck-Wellendichtung (55)kompatibel ist.
