FIELD: heat power engineering. SUBSTANCE: burner may be used in boiler furnaces, industrial furnaces and in different fuel burning-up installations. It provides for adjustment of torch length and parameters. Burner has several axially-positioned tubular members, diffuser with perforation, vortex generator in air circular channel, gas tube with circular collector and nozzles as well as outer body. Novelty is in provision for cup with internal thread positioned on circular gas collector and in external thread at gas tube end identical with internal thread of cup. Vortex generator in air circular channel is made fitting (over diameter) with respect to internal surface of body. Vortex generator (in zone of gas nozzles) is positioned in circular gas collector. EFFECT: higher efficiency. 3 cl, 1 dwg
