    The invention relates to burners with a radial-flat flame and can be used to conduct heating processes, heat treatment processes for melting and firing in the metallurgical, metal processing, metalworking and other industrial sectors.
    A radiation burner is known, comprising an air inlet housing with an outlet nozzle connected to a burner stone having a toroidal outlet embrasure, and central and peripheral tubes coaxially arranged with an annular gap, forming a mixing chamber with the nozzle connected to the cavity of the housing tangential channels made in the side wall of the nozzle (patent GDR No. 144950, CL F 23 D 17/00, published 1980).
    A disadvantage of the known burner is the low efficiency and low range.
    working zones in the flat torch.
    The purpose of the invention is to increase the efficiency by expanding the range of adjustment of the torch parameters.
    This goal is achieved by the fact that a radiation burner containing an air supply on the housing with an outlet nozzle connected to a burner stone having a toroidal outlet embrasure and coaxially arranged with an annular gap central and peripheral tubes forming the mixing chamber with the nozzle connected to the cavity of the housing through tangential the channels made in the side wall of the nozzle further comprises a guide washer placed in the annular gap with a number of holes located around the circumference The nozzles, which are inclined to the burner axis, are made in the form of a system of vanes that form tangential channels, and are equipped with a confusion-cylindrical nozzle at the outlet, the peripheral tube is installed with the possibility of longitudinal movement in the nozzle area, and the cylindrical section of the nozzle is inserted into the embrasure inlet section burning stones In addition, the holes of the guide washer are inclined to the axis of the burner at an angle of 20-40.

    longitudinal incision; in fig. 3 - the same, view; in fig. 4 is a section A-A in FIG. 3; in fig. 5 - guide washer, general view; FIG. 6 is a section BB in FIG. five.
    The radiation burner contains an air supply housing 1 with a nozzle 2 at the exit connected to the burner stone 3, having a toroidal exit embrasure 4 and coaxially located with the annular gap 5 central and peripheral pipes 6 and 7, respectively, forming with the nozzle 2 a mixing chamber 8 connected to the cavity of the housing 1 by means of tangential channels 9 provided in the side wall of the nozzle 2. The burner further comprises a guide washer 10 placed in the annular gap 5 with a number of holes 11 located About the circumference and inclined to the axis of the burner, nozzles 2 are made in the form of a system of blades 12 forming tangential channels 9 and equipped with a confused cylindrical nozzle 13 at the outlet, the peripheral tube 7 is installed with the possibility of longitudinal movement in the nozzle area 2, and the cylindrical section 14 of the nozzle 13 the nozzle 2 is inserted into the entrance section of the embrasure 4 of the burner stone 3. The holes 11 of the guide washer 10 are inclined to the axis of the burner at an angle of 20-40 °. The central tube 6 may be equipped with a fuel oil nozzle, a pilot burner or a device for igniting and controlling the flame,
    In order to seal the burner against the surrounding wall of the furnace, the burner stone 3 is provided with a support 15 for laying the sealing material. The burner is fixed in the burner stone 3 through the casing 16. I
    The radiation burner works as follows.
    Gas is supplied to the peripheral pipe 7 and through the holes 11 of the guide washer 10 enters the mixing chamber 8 as a swirling flow. Air into the mixing chamber 8 is supplied from the housing 1 through the tangential channels 9, made in the side wall of the nozzle 2. In the chamber 8, intensive mixing of swirling fuel and air flows is carried out, which continues into the toroidal embrasure 4 of the burner stone 3,
