Abstract

L'invention concerne un brûleur d'une chambre de combustion de turbine à gaz qui utilise une rampe d'injection d'un corps non profilé central et un entourage de brûleur pour former la zone de recirculation afin de stabiliser le processus de combustion. Le brûleur comporte notamment un corps principal cylindrique et une rampe d'injection. La rampe d'injection est placée à l'intérieur de la chambre de mélange carburant-air et comporte une partie base et un corps non profilé allongé. La partie base vient en prise avec le corps principal du brûleur de façon portante et le corps non profilé s'étend axialement en aval de la partie base traversant la chambre de mélange interne de manière à placer un point d'allumage en aval de ladite chambre. Dans un mode de réalisation représentatif, le brûleur comporte également un dispositif d'entourage de brûleur jouxtant la partie extrémité en aval du corps principal du brûleur. Ledit dispositif définit une chambre de recirculation intérieure et une sortie de brûleur. La chambre de recirculation intérieure est conçue pour recevoir des gaz de précombustion de la chambre de mélange et faire recirculer une partie des gaz produits par la combustion dans une direction en amont de façon à contribuer à la stabilisation de la combustion.
