Abstract (en)
[origin: EP0933593A2] The burner (1) is also capable of running on gaseous fuel (G) supplied via a channel (7) between the prim. and sec. supply channels (5, 6) for combustion air (L1, L2). The gaseous fuel supply channel leads into the inside of the atomising nozzle lip (3), opening out into the prim. and/or sec. air supply channel upstream from the nozzle edge (4) forming the rear end of the lip. The atomising nozzle (2) generates a spray cone (13) formed when the liquid fuel (F) impinges against a nozzle lip with a concentric arrangement relative to the nozzle central axis (X). The prim. air supply channel leading to the spray cone passes through the inside of the nozzle lip, whilst the sec. air supply channel extends over the outside of the lip, combining with the prim. air supply channel to form an enveloping flow of air.
