Abstract

La présente invention concerne une chambre de combustion perfectionnée pour moteur à turbine à gaz Selon un mode de réalisation, une combinaison de tubes de mélange de carburant/air de forme en serpentin déchargeant vers la zone radialement à l'extérieur de la chambre de combustion et un tube de mélange de carburant et d'air orienté axialement près du centre de la chambre de combustion est adapté pour créer un champ de force centrifuge important dans la chambre de combustion Le champ de force favorise le mélange rapide et la combustion dans la chambre pour réduire à la fois la température de la chambre de combustion et la période d'exposition de gaz à cette température. L'invention est applicable pour réduire la pollution due à l'émission d'oxyde d'azote.
