Abstract

La présente invention concerne un appareil de prémélange carburant-air utilisant un dispositif d'injection rotatif et un brûleur de turbine à gaz le comprenant, qui, pour son application sur des brûleurs cylindriques et annulaires, comprend un dispositif d'injection rotatif avec une vitesse de rotation pouvant être régulée, le dispositif d'injection rotatif étant installé dans l'appareil de prémélange d'un brûleur de turbine à gaz à faible pollution, de façon que la vitesse de rotation du dispositif d'injection rotatif soit régulée pour produire une force centrifuge permettant d'injecter de fines particules de carburant tout en maintenant une pression basse d'alimentation en carburant quelle que soit la sortie du moteur, et les fines particules de carburant sont mélangées avec l'air et fournies au brûleur. L'appareil de prémélange carburant-air de la présente invention comprend : un tube de mélange agencé devant une chambre de combustion et en communication avec celle-ci ; une pièce d'injection de carburant agencée dans le tube de mélange de façon à être mise en rotation pour injecter du carburant dans le tube de mélange ; une pièce d'alimentation en carburant servant à fournir du carburant à la pièce d'injection de carburant ; un premier dispositif rotatif agencé devant le tube de mélange autour de la pièce d'injection de carburant pour fournir de l'air dans le tube de mélange ; un deuxième dispositif rotatif agencé derrière le tube de mélange pour éjecter le gaz mélange air-carburant du tube de mélange dans la chambre de combustion ; et un moteur faisant tourner la pièce d'injection de carburant indépendamment de la puissance produite par la partie turbine.
