    1 The invention relates to the power industry, namely to the means of cleaning the heating surfaces of boilers from slag deposits. A device for removing slag from heating surfaces is known, comprising a peak in the form of a double-wall pipe with a closed end, a steam nozzle located in the side wall at the pipe end, and a liquid nozzle located on the side wall of the pipe at some distance from the end, and the interwall cavity communicated with a source of steam, and internally with a source of liquid С 1 and. A disadvantage of this device is the presence of two sealing assemblies on the supply of steam and liquid to the nozzles, which reduces the reliability of the device and the cleaning efficiency. The purpose of the invention is to increase the reliability of the device. This goal is achieved by the fact that a peak for blowers, containing a pipe with a closed end, a steam nozzle located in the side wall at the end of the pipe, and a liquid nozzle located on the side wall of the pipe, has a shutter with a hole for separating the end part of the pipe with a steam nozzle from the rest, a movable element for opening and closing the opening of the shutter and a driving element of the movable element consisting of elements that are sensitive to temperature changes and kinematically connected with the movable element. The driving member of the movable element consists of two elements with a different linear expansion coefficient, with the element with a large linear expansion coefficient at one end rigidly connected to the pipe, and the element with a lower linear expansion coefficient at one end rigidly connected with the first element, and its second end installed with the possibility of contacting the moving element by means of kinematic communication. The drive member with a large linear expansion coefficient is made in the form of a hollow cylinder with two end flanges, a. an element with a lower linear expansion coefficient — in the form of a rod mounted inside a hollow cylinder, the hollow cylinder on the side stack having an opening for introducing a liquid nozzle into the cylinder cavity, made with a gap to move the hollow cylinder relative to the liquid nozzle. The elements of the driving body of the rolling element are made in the form of rods. The drawing shows the peak for the blowers, a slit. The peak contains a pipe 1 with a closed end 2, a steam nozzle 3 located in the side wall at the pipe end, and a liquid nozzle 4 of smaller diameter located on the side wall of pipe 1 at some distance from the end 2. For determining the end part of pipe 1 with a steam nozzle 3 serve as a shutter 5 with a spherical orifice and movable element 6, which rotates around an axis 7 fixed in the shutter 5. The driving member of the movable element 6 consists of two elements with different linear expansion coefficients. heads, one of which is a bolt 5 with a hole, and a rod 9 mounted inside the hollow cylinder 8). The end flange of the hollow cylinder, forming the valve 5 with a hole, is rigidly fixed inside the pipe 1, and the other end flange is rigidly connected to the rod 9 through the holder 10 and is movable. inside the tube 1. The hollow cylinder 8 has a greater linear expansion coefficient compared to the rod 9. The rod 9c is connected with the movable element 6 by means of a kinematic connection consisting of two levers 11 and 12. The lever 11 is connected at one end to the rod 9 by an axis 13, the other with the lever 12 through the axis 14 and is rotatable about the axis 15 fixed in the hollow cylinder 8. The free end of the lever 12 is connected to the movable element 6 via the axis 16. The hollow cylinder 8 on the side wall has an opening 17 for size scheni therein liquid nozzle 4 while moving the hollow cylinder and an opening 18 for supplying steam or liquid into the cavity between the pipe 1 and the hollow cylinder 8. The apparatus operates as follows.
    When steam is supplied to the peak of the blower, the hollow cylinder 8 and the rod 9 are heated. Since these elements are made of materials with different linear expansion coefficients, the poplar cylinder 8 expands more along the axis of the peak than rod 9, as a result of which axis 13 moves to the left relative to axis 15 and lever 11 rotates clockwise and movable element 6 rotates around axis 7 and clears the hole in the bolt 5. The steam enters the nozzle 3 and it onto the surfaces to be cleaned. During the steam blasting process, a small amount of steam passes through the liquid-jet nozzle 4.
    When applied to the peak of the liquid, the usual
    water cooling effect of 20 Works.
    causes the hollow cylinder 8 and the rod 9 to contract along its peak, with the result that the lever 11 rotates counterclockwise and the movable
    element 6 closes the hole in the bolt 5. Since the hole in the bolt 5 is spherical, the movable element 6 forms intimate contact with the surface of the hole,
    while in front of the liquid nozzle 5, full pressure water is provided.
    The drive element of the rolling element can be made of rods with different linear expansion coefficients.
    The proposed device has one pipe for supplying steam or liquid to it, which increases its reliability.
