Abstract

Procédé accommodant des variations de température de la vapeur à des pressions élevées. Le système comprend des moyens 33, 37 pour mesurer la température réelle du fluide, des moyens 25 pour mesurer la pression réelle du fluide; des moyens 29 pour engendrer une courbe de température de saturation basée sur la pression réelle du fluide; et des moyens de comparaison 45, 49 de la courbe de température de saturation avec la courbe de température réelle; et des moyens 55, 59 pour actionner cette vanne de purge en fonction du signal de sortie de ces moyens de comparaison. Application aux centrales électriques.
