Abstract

L'invention concerne un procédé permettant de faire fonctionner un système de turbines à gaz et à vapeur (1), selon lequel on utilise dans un générateur (6) de vapeur de récupération de chaleur la chaleur contenue dans le fluide de travail détendu d'une turbine à gaz associée pour générer de la vapeur pour une turbine à vapeur associée (3) comportant au moins une partie basse pression (9) et une partie haute pression (7). Un étage basse pression (14) muni d'un tambour basse pression (48) est associé à la partie basse pression (9) dans le générateur (6) de vapeur de récupération de chaleur, les gaz dissous dans l'eau ou la vapeur sont sensiblement dégazés de la vapeur destinée à la partie haute pression (9) hors du tambour haute pression (48), et la production de vapeur dans le tambour basse pression (48) est modifiée pour la régulation du dégazage sous l'effet d'un déplacement de la chaleur à l'intérieur du générateur (6) de vapeur de récupération de chaleur, la chaleur étant déplacée à l'intérieur du générateur (6) de vapeur de récupération de chaleur du fait qu'une moindre quantité de chaleur est prélevée du fluide de travail dans un étage moyenne pression (42) ou haute pression (22) du système de turbines à gaz et à vapeur (1).
