    A burner for liquid fuels such as light, medium and heavy oil, in which a fuel supply pipe is concentrically located in an air supply pipe and partially enclosed by a sleeve carrying air. A spray diffuser and a twist-producing member encloses the fuel supply pipe upstream of the spray diffuser. The twist-producing member has a fixed blower wheel and receives combustion air from the periphery thereof. The combustion air quantity is regulatable upstream of the burner head as a function of the prevailing fuel flow. A space located between the twist-producing member and the air supply pipe, holds two additional air supply pipes. One of these additional air supply pipes, an innermost pipe, has an end cone directed towards the outside. Coaxially downstream from the twist-producing member enclosing the fuel supply pipe, there are two additional twist-producing members with opposite twist direction enclosing each other. One of these additional twist-producing members is an inner member having a twist direction corresponding to the twist direction of the first-mentioned twist-producing member. The smallest diameter of the inner twist-producing member is connected to an axial discharge opening of the main or first-mentioned twist-producing member enclosing the fuel supply pipe. The largest diameter of the outer twist-producing member is located between a cylindrical part of the inside air supply pipe and its outward directed end cone. A sliding link closes, at partial load of the burner, the intake to the other twist-producing member which is the main member enclosing the fuel supply pipe, the space between the two additional air supply pipes, and the intake to the outer twist producing member, whereas the sliding link opens these elements in other load regions of the burner.

    The invention relates to devices for burning fuel, in particular to burners for liquid fuel, and can be applied in heat and power engineering, metallurgy and other areas 5 tons.
    Closest to the invention, the burner is mainly for burning liquid fuel, comprising a housing connected to the air source through the flow controller with a central fuel pipe and installed coaxially with the inner, middle and outer shells communicated at the inlet with the housing and forming 5 peripheral, middle and central canals, the last of which is provided with a radial swirler at the entrance, as well as a swivel gate mounted with a possibility of longitudinal movement in the swirl zone and placed At the outlet, the axial guide apparatus t13 The disadvantage of the known burner is the low reliability due to the high degree of coking of the output nozzle of the burner.
    The purpose of the invention is to increase. reliability by reducing coking
    The goal is achieved by the fact that the burner, primarily for burning liquid fuel, contains a case connected through a flow regulator to the source of lift, with a centrifugal fuel tube and installed coaxially with the inner, middle and outer shells communicated at the entrance to the housing and forming a peripheral tube, the middle and central channels, the last of which is provided with a radial swirler at the entrance, as well as a spool pin mounted with the possibility of longitudinal movement in the swirler zone
    the ber and axial guiding device placed at the exit is equipped with two dampers installed with the possibility of longitudinal movement with a bracket fastened to them movably covering the fuel pipe, as well as with a diffuser outlet nozzle rigidly connected to the confused output section of the middle shell through the axial guide device made in the form of a central and peripheral coaxial annular blade crowns with a mutually opposite direction of the twist, and the diameter of the outer core The peripheral rim is equal to the minimum diameters of the confused section and the diffuser nozzle of the middle shell, and the diameter of the inner core of the central rim is equal to the diameter of the inner shell and adjoins its output end, the twist direction of the central rim coincides with the twist direction of the radial swirler. with the bracket, and one of the flaps of the latter is installed at the entrance to the middle arm, and the other - at the entrance to the peripheral crown guiding apparatus.
    In addition, the valve installed at the entrance to the middle channel, made in the form of an annular disk or a hollow truncated cone, and the valve installed at the entrance to the peripheral crown - in the form of an annular disk.
    The spool gate and the flap, located at the entrance to the peripheral hub, are secured to the bracket.
    The fuel pipe is installed with the possibility of longitudinal movement.
    The diffuser nozzles of the middle shell are brought out of the body and the outer shell.
    In addition, the outer shell is made with a confused output station.
    In this case, the body is made with confused output section.
    FIG. 1 shows a burner with a guide vane placed inside the shells, a longitudinal section; in fig. 2 - the same, with the guiding device displaced to the right relative to the shells; in fig. 3 - the same, with a shell, equipped with a confused outlet section; in fig. 4 - the same with the case, equipped with a 1m confused outlet section; in fig. 5 - the same with the guiding device, shifted to the right relative to the shells.
    The burner includes a housing I with a central fuel pipe 2 and installed coaxially with the inner 3, middle 4 and outer 5 shells communicated at the entrance to the housing I and forming peripheral 6, middle 7 and central 8 channels, the last of which is provided at the entrance with a radial swirler 9, as well as a spool 9 installed with the possibility of longitudinal movement in the swirl zone 9 and an axial guiding device disposed at the outlet.
    The burner is equipped with two dampers installed with the possibility of longitudinal movement with the help of fastened with them a brace 11, movably covering the fuel pipe 2, as well as a diffuser outlet nozzle 12 rigidly connected to the confused output section 13 of the middle shell 4 through an axial guide device made in the form of a central 14 and 15 peripheral coaxial annular blade rims with mutually opposite direction of twist, and the diameter of the outer forming peripheral rim 15 is equal to the minimum di meters confused area 13 and the diffuser nozzle 12 of the middle shell 4, and the diameter of the inner generators of the central crown 14 is equal to the diameter of the inner shell 3 and adjacent to its output end, the direction of twist of the central crown 14 coincides with the direction of twist of the radial swirl 9, around which the spool is located spool A spyber 10 fastened with a brace 11, and one of the dampers of the latter is mounted on the bottom in the middle channel 7, and the other at the entrance to the peripheral crown 15 of the sealing device.
    The valve installed at the entrance to the middle channel 7, is made in the form of an annular disk 16 and a hollow truncated cone, and a valve installed at the entrance to the peripheral I crown 15 - in the inner ring of disk 17.
    The outer shell 5 is complete with a confused outlet section 18, and case I with an confused outlet section 19.
    During the operation of the burner, the liquid fuel is supplied through the fuel pipe 2, and the air, which is previously swirled by the swirler 9, is fed through the channels 6-8, formed by coaxially installed inner 3, middle 4 and outer 5 shells.
    The air supply is controlled by the gate 10, movably fastened with the bracket II, when it is moved along the fuel pipe 2. When the load is incomplete, the bracket 11 with the valves fixed on it, made in the form of ring disks 16 and 17, is in the extreme right position . With increasing load bracket 11 should be moved to the leftmost position. Due to this, the task is completely solved and it is ensured that after the ignition, the resulting flame burns evenly and stably at partial load, as well as during the transition to full load and at full load without any deposition (coking) on any surface device, since going from partial load to full air can pass through the radial swirler 9 surrounding the fuel pipe 2, and by opening the supply to the peripheral rim 15 of the axial guide ata is created kontrzavihrenie. This reduces the influence of the air turbulence, which also comes through the swirler 9, as it is counteracted by the air turbulence. passing through the peripheral rim 15, whereby the droplets of fuel are thrown out. In order to achieve an accurate adjustment of the supply of the required amount of air at partial load, it is advisable to adjust the position of the gate 10 and the annular disk 17 on the movable bracket 11 and the fixed non-adjustable position of the annular disk 16. If this adjustment is done, the gate 10 and the annular disk I7 are set relative to the movable bracket 11 so that the air supply to the radial swirler 9, surrounding the heating pipe 2, as well as to the axial guide device, made in the form of the central 14 and The serial 15 coaxial ring Lopato GOVERNMENTAL crowns with mutually opposite. overlap in twist direction. To influence the shape of the flame, for example, to increase the diameter of the pellet, the fuel pipe 2 with a swirler 9, as well as the middle shell 4 and the gate O can move along the outer shell 5 so that the confusing output section 13 of the middle shell 4 is mainly behind the hole outer shell 5. It is also possible to provide the outer shell 5 with a confused outlet section. 18 so that the flame at partial and full load would have approximately the same diameter. If the outer shell-5 is equipped with a confused section 18, then with both types of load the diameter of the flame can be further narrowed, and the flame at this time becomes narrower. The narrow flame thus obtained can be made wide if the fuel pipe 2, the swirler 9 with the middle shell 4, the gate 10 and the annular disk 17 are moved relative to the outer shell 5. When the burner is installed with the regulating device, it is ensured that by reducing coking. 10 -16 Fig. Z Yu 16 iO 6 16 It 5 15 1 N / 7/5
