SWIRL BURNER

摘要

liquid hydrocarbon fuel burning equipment. SUBSTANCE: swirl burner has air supplying box, annular air channel, air supplying cone located inside box in axially aligned relation with respect to nozzle unit and communicating with box cavities and with annular channel via through windows. Axial nozzle unit is composed of multiplicity of nozzles. Peripheral two-gear blade-type swirler has outer axial gear and inner axial-tangential gear. Angle between blade outlet edges of inner axial-tangential gear and nozzle axis is selected such that tangential component of air flow speed at swirler outlet end is at least two times greater than axial component. EFFECT: increased efficiency and simplified construction. 6 cl, 2 dwg
