Title
(EN) COOLANT DELIVERY VIA AN INDEPENDENT COOLING CIRCUIT
(FR) DISTRIBUTION DE RÉFRIGÉRANT PAR L'INTERMÉDIAIRE D'UN CIRCUIT INDÉPENDANT DE REFROIDISSEMENT
Abstract
(EN)
An embodiment of an independent cooling circuit for selectively delivering cooling fluid to a component of a gas turbine system includes: at least one coolant feed channel fluidly coupled to a supply of cooling fluid; and an interconnected circuit of cooling channels, including: an interconnected circuit of cooling channels embedded within an exterior wall of the component; an impingement plate; and a plurality of feed tubes connecting the impingement plate to the exterior wall of the component and fluidly coupling a supply of cooling fluid to the interconnected circuit of cooling channels; wherein the cooling fluid flows through the plurality of feed tubes into the interconnected 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.
(FR)
L'invention concerne un mode de réalisation d'un circuit indépendant de refroidissement, permettant la distribution sélective d'un fluide de refroidissement à un élément d'un système de turbine à gaz et comprenant : au moins un canal d'alimentation en réfrigérant, couplé fluidiquement à une alimentation en fluide de refroidissement ; et un circuit interconnecté de canaux de refroidissement, comprenant : un circuit interconnecté de canaux de refroidissement, intégrés à l'intérieur d'une paroi extérieure de l'élément ; une plaque d'impact ; et une pluralité de tubes d'alimentation, reliant la plaque d'impact à la paroi extérieure de l'élément et couplant fluidiquement une alimentation en fluide de refroidissement au circuit interconnecté de canaux de refroidissement. Le fluide de refroidissement s'écoule à travers la pluralité de tubes d'alimentation dans le circuit interconnecté de canaux de refroidissement uniquement en réponse à la formation d'une brèche dans la paroi extérieure de l'élément, qui expose au moins l'un des canaux de refroidissement.
