Patent

CA 2577770

The invention relates to a lance (3) for a hybrid burner (2) of a combustion chamber (1) of a gas turbine. Said lance comprises: - an interior duct (10) for a liquid fuel; - an exterior duct (11) for a gaseous fuel, which coaxially surrounds the interior duct (10); - several outer nozzles (12) that are disposed in a stellar manner and extend radially from the exterior duct (11); - several inner nozzles (14) which extend radially from the interior duct (10) and run coaxially within one of the outer nozzles (12). respectively; - and a distribution section (18) that is located upstream of the outer nozzles (12) in the exterior duct (11) and is provided with several stellarly arranged, coaxially extending passages (19) for the gaseous fuel. In order to reduce the resistance to fluid flow in the gas path of the lance (3), the passages (19) are wider in the circumferential direction than they are in the radial direction.

L'invention concerne une lance (3) destinée à un brûleur hybride (2) d'une chambre de combustion (1) d'une turbine à gaz. Cette lance (3) comprend un canal intérieur (10) pour un combustible liquide, un canal extérieur (11) pour un combustible gazeux, ce canal extérieur (11) entourant coaxialement le canal intérieur (10), plusieurs buses extérieures (12) disposées en forme d'étoile et partant radialement du canal extérieur (11), plusieurs buses intérieures (14) partant radialement du canal intérieur (10) et s'étendant chacune coaxialement à l'intérieur d'une des buses extérieures (12), ainsi qu'une section de distribution (18) disposée en amont des buses extérieures (12) dans le canal extérieur (11) et présentant plusieurs ouvertures de passage (19) pour le combustible gazeux, ces ouvertures de passage (19) étant disposées en forme d'étoile et s'étendant coaxialement. Selon l'invention, pour réduire la résistance à l'écoulement dans la voie de gaz de la lance (3), les ouvertures de passage (19) sont plus larges dans la direction circonférentielle que dans la direction radiale.
