Abstract (en)
[origin: EP0692675A2] The method involves ending partition wall (17) of the pilot gas duct (13) and the outer air duct (12) in the direction of flow in front of the atomising cross-section (15) of the air-blast nozzle (2). The pilot gas duct opens into the air inflow pipe (14) or into at least one of the air ducts (11,12). The pilot gas duct is connected to the outer air duct, and the opening (18) is positioned inside the air-blast nozzle. The partition wall contains several evenly distributed holes (26) opening at a tangent into the outer air duct, and pointing in the opposite direction in which the blown air (5) is flowing. <IMAGE>
