    The invention relates to the combustion of solid fuels and m. used in stepped grates. The aim of the invention is to increase reliability. The lateral ends of the 2 grates (K), protruding / 1-L those outside their outer ribs 3. And located in the zone of maximum heat output, have a saw-tooth profile. The alternating teeth 4 and the notches 5 are closed on the side of the outer surface 6 and open in the opposite direction. The notches and teeth of the adjacent K are 7 longitudinally displaced by half of the pitch. Step 7 m. equal to twice the amount of movement of adjacent K. The side surfaces of the 8 teeth are inclined to the outer surface of the corresponding K at an angle of 20-50. The lateral ends K above the grooves have a height of 9, amounting to yup, th 0.25-0.33 of the entire height of these ends. Fuel particles trapped between K are displaced downwards by the cutting edges of the lateral ends of the neighboring K due to the action due to the tilting of the edges of the wedge. 4 hp f-ly, 3 ill. in O) cm

    And the acquisition relates to the combustion of solid fuel and can be used in fireboxes with grate stepped grates.
    The purpose of the invention is the reliability,
    Fig, I shows a section of the grate, formed from several grates moved relative to each other, top view; FIG. 2 is a section A-A in FIG. 1; Fig, 3 is a section bB in Fig.2,
    The grate contains movable in the longitudinal direction and installed with overlapping sections consisting of separate grates 1, installed with the possibility of moving relative to each other, and adjacent to each other surfaces of their lateral ends 2, protruding laterally beyond their outer ribs 3.
    The lateral ends of the 2 grates 1 outside the outer ribs 3, located in the zone of maximum heat stress, have a saw-tooth profile in the form of alternating teeth 4 and notches 5 closed from the outer surface 6 of the grate 1 and open in the opposite direction.
    The notches 5 and the teeth 4 of the adjacent heads 1 can be displaced in the longitudinal direction relative to each other by half of the step 7 of the teeth 4.
    The tooth 4 can be arranged in increments of 7 equal to twice the amount of movement of adjacent grates.
    The side surfaces of the 8 teeth 4 are inclined to the outer surface 6
    the corresponding grate 1 at an angle of 20-50,
    The side ends 2 of the grate 1 above the notches 5 have a height of 9, which constitutes (0.25-0.33) of the entire height of the ends 2.
    When the grating is in operation, if particles of fuel fall between the grate 1, these particles are forced out of the cut by the edges of the grate. the ends of 2 neighboring grates 1 due to the resulting, due to the inclination of the cutting edges, the action of the wedge down. .
    This embodiment of the grate makes it possible to increase the reliability of its operation by preventing fuel particles from entering between the grates.

    Invention Formula
    1, The grate mainly for the firebox, containing sections that are movable in the longitudinal direction and installed with overlap, consisting of individual grates installed with the possibility of moving relative to each other, and adjoining one another to the surfaces of their side ends external ribs, from a flair, so that, in order to increase reliability, the lateral ends of the grates outside the outer ribs located in the zone of maximum thermal stress have a sawn profile the form of alternating teeth and recesses closed from the outer surface of the grate and open in the opposite direction.
    2, a grate according to claim 1, characterized in that the recesses and teeth of the adjacent grates are displaced in the longitudinal direction relative to each other by half a tooth pitch,
    3, the grate according to Claim 3, characterized in that the tooth is arranged in steps equal to twice the amount of movement of the adjacent grate,
    0 4. The grate according to claim 1, 1-3, characterized in that the side surfaces of the teeth are inclined to the outer surface of the corresponding grate at an angle of 20-50.
    5 5. A grate according to claims 1-4, distinguishing. due to the fact that the lateral ends of the grates above the grooves have a height of (0.25 - 0.33) of the entire height of these ends.
