Abstract
Brûleur à air soufflé destiné à brûler un combustible gazeux tout en produisant de faibles rejets de NOx, de CO et d'hydrocarbures, qui comporte une coque externe (8) comprenant un caisson d'admission d'air et une partie tubulaire resserrée (13) en communication fluidique avec ledit caisson, un corps (16) généralement cylindrique monté dans ladite coque coaxialement avec la partie tubulaire et espacé intérieurement de cette dernière, un canal d'écoulement annulaire étant défini entre le corps et la paroi interne de la section tubulaire, ledit canal constituant une gorge (14) pour les gaz oxydants venant du caisson d'admission d'air et possédant une extrémité de sortie aval pour lesdits gaz, et un dispositif destiné à entraîner un flux des gaz oxydants du caisson d'admission d'air jusqu'à ladite gorge, une brique de brûleur (28) servant de divergent étant jointe à l'extrémité de sortie de la gorge et définissant une zone de combustion pour ledit brûleur. Une pluralité de pales de tourbillonnement axiales incurvées (20) sont montées dans le canal d'écoulement annulaire pour conférer un tourbillonnement aux gaz oxydants coulant vers l'aval dans la gorge. Un dispositif d'injection de gaz combustible est situé dans le canal d'écoulement annulaire à proximité des pales de tourbillonnement pour injecter ce gaz dans le flux de gaz oxydants en un point situé en amont de l'extrémité de sortie.
