Zusammenfassung
(DE)

Eine Dampfturbine (3) weist eine Ventilanordnung (5) für die Regelung der Frischdampfzufuhr in die Turbine auf mit zwei Regelventilen (6, 7), die in Serie geschaltet sind. Die zwei Regelventile (6, 7) ermöglichen einen stufenweisen Abbau des Frischdrucks und gewähren eine Betriebssicherheit im Fall eines Teillastbetriebs der Turbine. Die Ventilanordnung ist insbesondere für Dampfturbinen ohne Regelstufe im Festdruckbetrieb geeignet.
