Abstract

Il est décrit une chambre à combustion pour une turbine à gaz comprend des chemises intérieure et extérieure définissant une chambre de combustion annulaire et au moins un anneau de ramassage disposé sur chacune des chemises intérieure et extérieure de la chambre de combustion. L'anneau de ramassage comprend une base intérieure radiale solide percée d'alésages qui donnent sur la chambre de combustion et forment des admissions de dilution d'air. L'anneau de ramassage comprend une partie extérieure radiale en forme de cuillère dont la face ouverte peut recevoir un flux d'air annulaire à haute vitesse. Les alésages des admissions qui donnent sur la partie de l'anneau en vue de diriger le flux d'air dans la chambre de combustion, dans laquelle les alésages des admissions forment des tuyères servant à fournir pénétration et orientation au jet d'air à l'intérieur de la chambre de combustion.
