Abstract

Zur Verbesserung des Anfahrverhaltens sowie der Stillsetzzeiten eines Kraftwerks (2), welches mehrere Komponenten umfasst, nämlich einen Kessel (4), eine Dampfturbine (6) und wahlweise eine Gasturbine (8) ist ein Verfahren vorgesehen, bei dem bei Stillstand des Kraftwerks (2) die Bauteiltemperatur von zumindest einem Bauteil einer der Komponenten (4, 6, 8) durch Wärmeaustausch mittels eines Fluidstroms (11) gesteuert wird.
