Abstract

La présente invention concerne un procédé d'amélioration du comportement de démarrage ainsi que des temps d'immobilisation d'une centrale électrique (2) comportant plusieurs composants, à savoir un générateur de vapeur (4), une turbine à vapeur (6) et éventuellement une turbine à gaz (8). Selon ledit procédé, en cas d'immobilisation de la centrale électrique (2), la température d'au moins un élément structural de l'un des composants (4, 6, 8) est régulée par échange de chaleur à l'aide d'un flux de fluide (11).
