Abstract

Die Erfindung betrifft ein Verfahren zum Betreiben einer mehrstufigen Dampfturbine (4, 5, 6), wobei die Dampfturbine (4, 5, 6) für hohe Temperaturen geeignet ist, wobei der Rotor (27) als Schweißkonstruktion mit einer ersten Komponente (33) und einer zweiten Komponente (34) ausgeführt wird und der Dampfturbine (4, 5, 6) nach einer Zwischenstufe (14) ein Kühlmedium zugeführt wird, wenn die Dampfturbine (4, 5, 6) im Schwachlastbetrieb oder im Leerlaufbetrieb sich befindet. Dadurch werden die thermischen Belastungen im Abströmbereich (32) der Dampfturbine (4, 5, 6) gesenkt.
