RADIATION GAS BURNER Russian patent published in 2004 - IPC

FIELD: burning gaseous fuel; radiation gas burners. SUBSTANCE: proposed radiation gas burner includes housing connected with gas-and-air mixture mixing and supply system, flow divider and metal screen radiator mounted in housing. Radiator includes upper and lower screens (in way of flow) having meshes of different sizes. Radiator screens form inner cavity as biconvex or convex-concave lens. Size of meshes of lower screen is lesser than that of upper screen; its convexity is directed towards flow of gas-and-air mixture. EFFECT: improved quality of burning gaseous mixture; reduced content of nitrogen and carbon oxides in combustion products; enhanced efficiency. 5 cl, 3 dwg, 1 tbl
