专利说明:

 . 1 The invention relates to the combustion of solid fuels and can be used in furnaces with grate stepped grates. The grates are well-known: e in the form of a slab with a curved front end groove located along the rear face, cut in one of the side and longitudinal ribs. The disadvantage of these grates is their nt1zka reliability, due to falling into the air gap formed by the notch with the side end of the neighboring grate, pieces of coal, which leads to a decrease in the flow of air to the combustion and abrasion of the ends of the grate. The aim of the invention is to increase reliability. This goal is achieved by the fact that in the extreme edge, located on the side of the recess in the side end of the slab, a hollow is made in the zone of the latter. In addition, a hole in the wall of the cavity 1 is filled with an air passage, the hole is located on a section of the wall adjacent to the plate, a transverse plate is installed in the depression along the edge, having a hole for pulling out the dip, the plate can be installed with a slope in the direction of the wall of the cavity. FIG. 1 shows the grate (option one), VIA from the bottom; in fig. 2 shows section A-A in FIG. 1 in FIG. 3 - section B-B on (} Ig. 2 in Fig. 4 - grate (variant two), bottom view, - in Fig. 5 - section B-B in Fig. 4; in Fig. 6 - section G-D in Fig. 5, in Fig. 7 - the wheelwright (third variant), bottom view, in Fig. 8, a section dD in Fig. 7: in Fig. 9, a section E-E in Fig. 8, in Fig. 10 - W-section in Fig. 9. The grate is made in the form of a plate 1 with a curved front end 2, a groove 3 located along the rear end 4, a notch 5 in one of the side ends 6 and longitudinal extreme 7 and 8 middle 9 and 10 ribs In the extreme edge 7. located on the side of the notch 5 in the side mountaineer 6 of the plate 1. in the zone of the last Nena cavity 11. The wall 12 in
which made the hole 13 for the passage of air. Hole 13 is located in the area 14 of the wall 12 adjacent to the plate 1 (option one). In the cavity 11 along the edge 7, a plate 15 is installed along the plate 15 and provided with a hole 16 for withdrawal of the dip (va-, second option). Plate 15 is installed with: Tilting in the direction of the wall 17 of the cavity 11 and forms with it a hole 16 for the view of the dip (third option). In the wall 17 of the groove 3, a window 18 is provided for F (air inlet).
The grate 3 rests on the support 19, and the curved front end 2 on the slab below the located grate. In the lower part of the plate 1 along the ribs 7 and 8 there is a plate 20, forming / with the ribs 7 - 10 channels 21} l of air passage. The notch 5 of the lateral end of the port forms with the butt of the adjacent colonic column 22 for the passage of air, and the depression 11 has edges 7 with the edge 8 of the neighboring grate - chamber 23 for failure.
The device works as follows,
The air required for burning the fuel enters through the window 18, groove 3 located in the wall 17, passes through the channels 21, while cooling the plate 1, through the opening 13 enters the chamber for failure 23 from which through the opening. 22 s.1 goes to the burning zone of the toptsva located on the plate 1.
A particle of fuel entering from the layer B of the hole 22 is further dropped into the kayer: 23 onto the plate 1 below located to: polosnik (option one) or onto the transverse plate 15 and further through the hole; 16 - also on the plate 1 (option two). When the grates move, the dip is pushed by the front end 2 along plate 1 to the rear end 4 and dumped into the sublattice space. In the third embodiment, the dip falls onto the H of the inclined plate 15, moves along it and through the hole 13
for the passage of air, placed in the lower part of the depression 7, enters the channel 21 and is discharged through the window 18.
Due to the presence of a chamber for failure 23, channels 21 do not have chaotic felled fuel, thereby ensuring uninterrupted supply of air to the combustion zone, as well as eliminating the possibility of jamming of grates and wear of the side ends 6 of plate 1, which greatly increases the reliability of the grate.
