Abstract

Die Erfindung betrifft eine Dampfturbinenanlage sowie ein Verfahren zur Kühlung einer Dampfturbine (1). Es ist vorgesehen, dass die Dampfturbine (1) über eine externe Kühldampfleitung (14) gekühlt wird, wobei zwischen der Kühldampfleitung (14) und einer Frischdampfzuführung (10) eine Querleitung (21) mit einem Querleitungsventil (23) angeordnet wird, das bei einem plötzlichen Druckabfall öffnet, wodurch das unter hohem Druck stehende Kühlmedium in einen Einströmbereich (13) der Dampfturbine (1) abgezweigt wird, wodurch eine Schädigung von dünnwandigen Komponenten vermieden wird.
