FIELD: engines and pumps. ^ SUBSTANCE: burner device incorporates a central fuel jet and coaxial circular rings forming air feeding channels provided differently directed blade swirlers and tapered deflectors arranged at the output of every channel to deflect air flows from the center to periphery. Here, the swirler adjacent blade inclination angles are set be different with the 0.5 to 0.8 ratio. ^ EFFECT: higher uniformity of heating the furnace space by intensifying air turbulence in crossing its swirled flows. ^ 3 dwg |
