Title
(EN) COOLANT DELIVERY VIA AN INDEPENDENT COOLING CIRCUIT
(FR) DISTRIBUTION DE LIQUIDE DE REFROIDISSEMENT PAR L'INTERMÉDIAIRE D'UN CIRCUIT DE REFROIDISSEMENT INDÉPENDANT
Abstract
(EN)
A coolant delivery system for a component of a gas turbine system includes: a plurality of independent circuits of cooling channels embedded within an exterior wall of the component, each independent circuit of cooling channels including a plurality of headers and a plurality of feed tubes fluidly coupling the plurality of headers to a supply of cooling fluid; and an impingement plate connected to the exterior wall of the component by the plurality of feed tubes of the independent circuits of cooling channels, wherein, in each of the plurality of independent circuits of cooling channels, the cooling fluid flows through the plurality of feed tubes and the plurality of headers into the circuit of cooling channels only in response to a formation of a breach in the exterior wall of the component that exposes at least one of the cooling channels of the circuit of cooling channels.
(FR)
L'invention concerne un système de distribution de liquide de refroidissement pour un composant d'un système de turbine à gaz comprenant : une pluralité de circuits indépendants de canaux de refroidissement intégrés à l'intérieur d'une paroi externe du composant, chaque circuit indépendant de canaux de refroidissement comportant une pluralité de collecteurs et une pluralité de tubes d'alimentation raccordant de manière fluidique la pluralité de collecteurs à une alimentation en fluide de refroidissement ; et un plateau de contact raccordé à la paroi externe du composant par la pluralité de tubes d'alimentation des circuits indépendants des canaux de refroidissement, le fluide de refroidissement s'écoulant, dans chaque circuit de la pluralité de circuits indépendants de canaux de refroidissement, à travers la pluralité de tubes d'alimentation et la pluralité de collecteurs dans le circuit de canaux de refroidissement uniquement en réponse à la formation d'une brèche dans la paroi externe du composant qui expose au moins un des canaux de refroidissement du circuit de canaux de refroidissement.
