Abstract

Une centrale électrique à cycle mixte comprend un dispositif de détection des débits de vapeur au niveau des entrée/sortie d'un système de refroidissement à vapeur. Un temps de fin de réchauffement du système de refroidissement à vapeur est déterminé au moment du démarrage à partir de la déviation des débits d'entrée/sortie. Lorsque la déviation du débit de vapeur au niveau de l'entrée, par rapport au débit de vapeur à la sortie du système de refroidissement à vapeur tombe en-deçà d'une valeur acceptable, il est établi que l'air résiduel et le drain ne sont pas diffusés et le réchauffement est achevé, ceci permettant au fluide de travail de continuer son cycle et de mettre en oeuvre une turbine à gaz.
