Abstract

La présente invention concerne une chambre de combustion annulaire (RBK) pour une turbine à gaz, qui permet un refroidissement à air en circuit fermé, de façon à obtenir de hautes puissances et des rendements élevés, avec de faibles émissions de Nox. Le boîtier en deux parties (1, 3) de la chambre de combustion annulaire entoure une gaine scellée à parois minces (4, 41) qui guide de manière étanche le gaz chaud provenant du brûleur (5) jusqu'à l'entrée de la turbine (8). Un espace annulaire variable (7) se trouve entre la gaine et le boîtier (1, 3) de la chambre de combustion annulaire. De l'air de refroidissement s'écoulant dans le sens inverse du gaz chaud est collecté dans cet espace annulaire et est apporté aux brûleurs (5) (« refroidissement à air en circuit fermé »). La surface de la gaine (4, 41) est refroidie de manière variable avec des dispositifs de refroidissement par impact (14) et des modèles perforés de refroidissement par impact en (1, 3). La gaine thermo-élastique, constituée d'anneaux soudés par soudage à l'arc sous flux en poudre, n'est fixée axialement que sur le rebord (36) et présente des moulures périphériques de renfort. La gaine (4, 41) à extension libre est suspendue de manière concentrique sur le boîtier (1, 3) de la chambre de combustion annulaire par des éléments de tension élastiques (10). Cette construction efficace, économique et simple offre en outre un avantage important au niveau du service, de par les mesures de construction suivantes : - les brûleurs (5) peuvent être complètement (dé)montés depuis l'extérieur, sans ouvrir le boîtier. - la gaine (4, 41) et un anneau qui intègre la première série d'aubes directrices de la turbine dans la chambre de combustion annulaire peuvent être retirés sous forme de pièces de service, c'est-à-dire sans ouvrir le boîtier de la turbine et du compresseur et sans retirer le rotor.
