    However, in the known burner there is no device preventing the removal of the container when the powder feed channel is open. Therefore, when replacing the container, it is possible that the powder gets into the channel of the burner body, which leads to its contamination and decrease, respectively, of its reliability.
    The purpose of the invention is to improve performance and increase reliability.
    This goal is achieved in that in a burner for flame spraying of powdered materials, comprising a housing with channels for supplying combustible gas, an oxidizer, a carrier gas, a combustible gas mixture and a gas-powder mixture, an injector for combustible gas and an oxidizer, an injector for a carrier gas and powder, shut-off valves installed in the channels for supplying combustible gas, oxidizer and carrier gas, and a device for supplying powder with a removable container; a device for supplying powder is equipped with a carrier plate connected to the burner body an intermediate member having a locking organ and mounted on the plate with the possibility of translational movement when closing overlapped orga prefecture powder feed duct, which is arranged in the intermediate element. The locking member is made in the form of a shutter, which, when the powder supply channel is open, has access to the spring-loaded retainer position of the intermediate element installed in the carrier plate. In addition, the locking member can be made in the form of a rotary disk with a hole for the passage of powder, with two circular grooves and two rectilinear grooves in the carrier plate, one of which connects circular grooves at the ends, and the other is attached to the free end of one of the circular channels, with the intermediate element having circular grooves located opposite the circular grooves in the carrier plate, and on the rotary disk there are diametrically opposed to each other.two pins installed in the cables her plate is movable on them. A cavity, the diameter of which exceeds the diameter of the carrier gas feed channel, is made in the burner housing at the inlet to the carrier gas injector and the powder. Moreover, between the nozzle and the confuser of the injector for the carrier gas and the powder, there is a spacer with a hole for the passage of the powder. Shut-off valves in the oxidant and combustible gas supply channels are provided with a common control unit. . The governing body of the shut-off valves is designed as a rotary lever, alternately interacting with the control elements of the shut-off valves. Fig. 1 shows the burner, general view, in longitudinal section (without exit section of the burner); FIG. 2, section A-A in FIG. one; Fig. 3 shows an embodiment of a device for feeding powder; in fig. k is a section BB in FIG. 3; in fig. 5 is a section B-B in FIG. 3. The burner comprises a housing consisting of two parts 1 and 2, and made with channels for supplying a combustible gas 3, an oxidizer 4, a carrier gas 5B using oxygen as an oxidant and a carrier gas through the tube 6, the shut-off valves 7 and 8 are installed in the channels k and SВ of the oxygen and combustible gas supply channels, which are controlled by the lever 9. pivoting around the axis 10, and having working surfaces 11 and 12 respectively acting on the control element 13 of the shut-off valve 7 and control element AND locking valve 8, the working surfaces 11 and 12 are designed in such a way that when turned off, valve 8 is first triggered, and then valve 7 opens valve 1 first when turned on. In channel part 1, channel 15 is provided for supplying the gas-powder mixture and channel 16 to supply a mixture of oxygen and combustible gas. In part 1 of the housing, an injector is installed, a curtain for a combustible gas and an oxidizing agent, which contains a nozzle 17 with an inlet filter 18, a confuser 19 and a spacer ring 20, which may have a different thickness. Spreader ring 20 has an opening 21, which connects the mixing cavity of the injector with channel 3 for the supply of combustible gas. In channel 3 there is a control valve 22, which serves to regulate the amount of fuel supplied to the combustible gas injector. The nozzle 17 is installed in the housing on the thread and its position relative to the confuser can be adjusted. Filter 18 protects the injector from dust and other impurities. At the entrance to the channel T5 in part 1 of the housing, an injector for carrier gas and powder is installed, comprising a nozzle 23 with a filter 2, a confuser 25 and a spacer 26 with an opening 27 for the passage of powder. All elements of this injector are replaceable. The position of the nozzle 23 is adjusted by fitting it to the thread. Both of the described injectors are easily dismantled after removal of part 2 of the burner body. In part 1 of the housing, a cavity 27 is made at the inlet to the injector for the carrier gas and powder; the diameter of which exceeds the diameter of the channel 5. The presence of the cavity 27 prevents the back diffusion of gas and, moreover.
    . the gas filling the cavity cleans the injector channels from the powder.
    A device for feeding powder contains a carrier PLI.TU 28, rigidly connected with the burner body and made with lateral rectilinear guides 29, and an intermediate element 30 mounted on the guides 29 with the possibility of movement. Moreover, this movement is limited on one side by an emphasis 31 support plate 28. The carrier plate 28 and the intermediate element 30 are made respectively with the channels 32 and 33 for supplying powder, which are located coaxially in the working position (Fig. 1) and are hermetically sealed outside by means of a sealing ring FOR A 0-shaped view, located between the carrier plate and the intermediate element. Channel 32 is adjacent to the burner housing channel 35. In the interstitial element 30, a flap 36 is movable in longitudinal tension. The flap 36 end is made in the form of a plate located in the final position of the flap between a pair of O-shaped seals 37 and 38 surrounding the channel 33 - The other end of the flap 36 protrudes from the intermediate element and closes in the open position of the valve the recess 39 in the carrier plate 28. In the recess there is a lock of the position of the intermediate element, including a spring-loaded button 40, protruding in a quiescent state above the surface of the carrier plate 28. The kO pack is only available when the valve 36 closes the powder feed channel 33. If the kO button is recessed, the intermediate element can be extended over the carrier plate 28 and can be removed. the closed flap 36, the Q button prevents the intermediate element from being removed and thus the powder escapes through the open channel
