FIELD: machine building.SUBSTANCE: invention relates to devices for combustion of gaseous fuel on an inner surface of a furnace lining, its warm-up and transmission of radiant energy to a product coil and can be used namely in high-temperature tubular furnaces. A horizontal flame burner includes sleeve 4, inside which cylindrical shell - air duct 3 is installed, gas supply tube 1 connected to gas header 2, flame spreader 8 installed with a gap relative to an outlet end face of cylindrical air duct 3 and pilot burner 6. A peculiar feature of the burner is that gas header 2 is made in the form of an annular distributing chamber with radial holes, which is arranged between flame spreader 8 and the outlet end face of air duct 3. Gas supply tube 1 and pilot burner 6 are located in a gap between air duct 3 and sleeve 4.EFFECT: burner is able to operate on any fuel without any flashback at a reduced noise level.3 cl, 2 dwg |
