Abstract

Le système de commande des températures de turbines à basse pression comprend un contrôleur 80 de réchauffeurs de vapeur de cycle 14, 16 pour commander l'opération de transfert de chaleur dans un réchauffeur de vapeur de cycle en fonction des températures de vapeur et de métal dans au moins un élément à turbine basse pression 18, 20, 22, ces températures étant commandées par une boucle fermée en fonction de limitations constructives de la turbine basse pression. Le contrôleur 80 de réchauffeurs commande deux réchauffeurs 14, 16, chacun utilisant une ou plusieurs sections de réchauffement qui réchauffent la vapeur s'écoulant à travers pour alimenter une ou plusieurs turbines BP par des orifices d'entrée latéraux séparés.
