Summary:metallurgy; combustion melting furnaces and thermal units. SUBSTANCE: oil-gas burner has pipe for delivery of oil terminating in nozzle, spraying agent supply pipe with Laval nozzle and gaseous fuel supply pipe with nozzle. Inlet diffuser section of gas nozzle is curvilinear in form. Length of diffuser section ranges from 0.55 to 0.65 of total length of gas nozzle and profile of surface at nozzle inlet is convex in shape at curvature radius of 0.5 of diameter of nozzle inlet section and curvature center lying in nozzle axis. Profile of surface at nozzle inlet is engageable with profile of surface at nozzle throat section whose curvature radius is equal to its diameter and curvature center lies at distance of 1.5 of diameter of nozzle throat section from nozzle axis; outlet hole for delivery of spraying agent coincides with end of confuser section of gas nozzle. Oil nozzle is located at inlet of cylindrical section of spraying agent nozzle. EFFECT: constant kinetic energy of jet at varying ratio of gaseous and liquid fuel. 1 dwg
