FIELD: heat-power engineering; gas burners with forced delivery of air; farming; public services; various gas equipment. SUBSTANCE: proposed gas burner includes air supply chamber, gas supply chamber with row of opposite holes in end walls, mixing tubes with circular row of holes in side walls and flame tube. Gas supply chamber is mounted between air supply chamber and flame tube, thus forming circular gap between its side cylindrical wall and flame tube; mixing tubes are hermetically mounted in holes of end walls of gas supply chamber whose side cylindrical surface is provided with circular row of radial holes; holes in side walls of mixing tubes are located inside gas supply chamber. EFFECT: reduced losses in pressure head in air line; reduced level of noise; simplified construction; facilitated procedure of assembly. 4 cl, 2 dwg |
