Abstract
Steuerstufe zur Regulierung der Dampfzufuhr bei Teilastbetrieb einer axialen Dampftur bine. Um zusätzliche Energieverluste, die durch thermische und dynamische Spannung im Teillastbetrieb entstehen, zu reduzieren, wird das erste Leitradgitter (4), welches dicht von einer Steuerplatte (2) umgeben ist axial, das heisst senkrecht zu allen folgenden Stufen der Turbine montiert. Die Leitschaufeln (4) der Steuerstufe müssen ungekrümmt sein, damit die profilierte Platte (2) frei vor und zurück entlang der Schaufeln bewegt werden kann, wodurch die Dampfzufuhr reguliert wird und der Dampfstrom in axialer Richtung gedreht wird. Die Steuerstufe kann bei Turbinen mit seitlicher wie auch mit zentraler Dampfzufuhr verwendet werden.
