FIELD: metallurgy, mechanical engineering, oil refining, and other industries; gas combustion in heating furnaces and heat-generating sets using indirect radiation heat transfer conditions. SUBSTANCE: burner has air-feed case 1 with shielding cover 5 and tangential swirler 3 with gas-feed pipe 4. Case 1 is installed in wall of furnace chamber lined with burner stone 2. Swirler 3 is installed along axis of case 1. End space of swirler 3 is contracting into annular gap for gas escape in radial direction. Gap is spaced 0.25-0.25D from burner stone surface, where D is burner case diameter. EFFECT: enlarged functional capabilities. 2 dwg |
