Abstract

L'invention concerne des brûleurs pour chambres de combustion dont plusieurs sont installés dans les parois de celles-ci, de manière que le combustible et l'air y soient injectés tangentiellement Chaque brûleur comprend un injecteur à tourbillonnement pour le combustible et une boîte à vent cloisonnée de façon à former un conduit d'air primaire, un conduit d'air secondaire et un conduit d'air en tourbillonnement qui est muni de vannes de réglage et dont la sortie est proche de la sortie de l'injecteur de combustible qu'elle entoure concentriquement. Les conduits d'air primaire et d'air secondaire peuvent aussi être équipés de vannes de réglage et sont disposés de manière à former un rideau d'air isolant la flamme des parois de la chambre de combustion.
