Abstract (en)
[origin: EP0851172A2] The combustion air (7) flows through tangential air inlet ducts (5,6) into a pre-mixing section formed by the burner. A critical spin-flow formed at the burner's outlet and induces a backflow zone to stabilise the flame-front. The burner along the flow direction has at least one zone(27) in which extra air is injected into the spin flow. The burner consists of at least two hollow, conical, interfitting part bodies (1,2) with staggered centre axes (3,4). The adjacent walls of the part-bodies for tangential air inlet ducts for the combustion air. At least one fuel nozzle (15) is contained in the conical hollow space formed by the part bodies.
