Abstract

Für eine zuverlässige und mit einfachen Mitteln durchführbare Erzeugung von überhitztem Dampf aus Sattdampf wird erfindungsgemäß ein erster Teilstrom t1 des Sattdampfes gedrosselt, bevor er durch Wärmetausch mit einem zweiten Teilstrom t2 des Sattdampfes überhitzt wird. Eine Dampfturbine (2), die mit derart überhitztem, aus einer Dampftrommel (24) ihres Wasser-Dampf-Kreislaufs (34) entnommenem Sperrdampf (SD) bespeist wird, ist auch beim Wiederanfahren nach einem Nachtstillstand einer besonders geringen Gefährdung durch Korrosion ausgesetzt.
