Abstract (en)
[origin: EP0769655A2] The nozzle (2) consists of a liquid fuel pipe (12) around the nozzle's axle (11), with at least one fuel (4)dispenser onto an atomiser edge (19). Two concentric air ducts (13,14) are fed by an air inlet pipe (15), with concentric pilot gas duct (22). The ducts are separated by partitions (18). The air ducts (13,14) on the nozzle's atomiser cross-section (16) open into the burner's inner chamber (17). The partition between the inner (14) and outer (13) air duct forms the atomiser edge and is held by inner and outer support elements (21). The inner support elements are positioned between the partition and the fuel pipe, and the outer support elements are positioned between the partition and the outer nozzle body (23).
