Abstract

On décrit une centrale électrique à cycle mixte qui effectue le mélange le plus adapté lorsque de la vapeur ayant refroidi une partie à température élevée d'une turbine à gaz dont la température doit être élevée, est mélangée à d'autres vapeurs; cette installation assurant la sécurité des systèmes situés en aval et fonctionnant de manière stable pendant une longue période. Cette installation comprend une canalisation (700) de mélange dans laquelle de la vapeur rejetée par un système (400) de refroidissement à vapeur qui assure le refroidissement d'une partie à température élevée d'une turbine (101) à gaz devant être refroidie par la vapeur, est mélangée à de la vapeur de dérivation et autre; la vapeur rejetée par le système (400) de refroidissement à vapeur qui a été chauffée lorsqu'elle a refroidi la partie à température élevée devant être refroidie de la turbine (101) à gaz et la vapeur de dérivation et autre n'ont pas été introduites dans la partie à température élevée qui a été refroidie, mais ont été dérivées pour réguler le débit et la température de la vapeur introduite dans la partie à température élevée qui a été refroidie et sont introduites dans la canalisation (700) de mélange pour se combiner de manière à produire de la vapeur surchauffée mixte dont la pression, la température et autre sont uniformes, ceci ayant pour effet de mettre à l'abri les systèmes situés en aval de son influence indésirable et négative.
