Abstract
(DE)
Die Erfindung betrifft eine Dampfturbine (1), die Leitschaufeln (5) aufweist, wobei zumindest eine Leitschaufel (5a) einen Hohlraum (6) hat. Der Hohlraum (6) ist mit einer Fluidleitung (7) zur Einspeisung von Fluid (8) sowie mit Öffnungsleitungen (9a, 9b) verbunden, die an der äußeren Oberfläche (10) der Leitschaufel (5a) münden. Die Erfindung betrifft weiterhin ein Verfahren zur Kühlung der Dampfturbine (1) in einem Ventilationsbetrieb.
(EN)
This invention concerns a steam turbine (1) which has guide vanes (5a). At least one guide vane (5a) has a hollow space (6). This hollow space (6) is connected with a fluid line (7) for introducing fluid (8) as well as port ducts (9a, 9b), which open at the outer surface (10) of the guide vane (5a). The invention also concerns a process for cooling the steam turbine (1) in ventilation operation.
(FR)
L'invention concerne une turbine à vapeur (1) pourvue d'aubes directrices (5a). Au moins une aube directrice (5a) présente un espace vide (6). Cet espace vide (6) est relié à une conduite à fluide (7), ainsi qu'à des conduites d'ouverture (9a, 9b) qui débouchent à la surface extérieure (10) de l'aube directrice (5a). L'invention concerne également un procédé pour le refroidissement de la turbine à vapeur (1) fonctionnant en mode ventilation.
