Description

For burning bonfires under the boiler, a firebox is offered using two inclined grates placed in it, forming with the walls of the firebox a type of boxes for loading fires through the doors, what is burned under the grates with the direction of the combustion products in the passage between the grates.

In FIG. 1 depicts the bottom; a river section of water-tube boilers with the proposed furnace; FIG. 2 is a section along the line EM in FIG. one; FIG. 3 and 4 are two types of squares j) emeTKH; FIG. 5-cross-section of the boiler CUT with a flame tube; FIG. 6 is a section along the line LP in FIG. 5 and FIG. 7 front view of the firebox.

The proposed firebox consists of two, placed on the sides of the firebox, replverts (figs 1, 2, and 5), assembled each of the longitudinal squares 4 (figs. 1-5), connected with crossbars 3 installed at an angle of 35-40 to the horizontal, what's the height of the free -start squares 4

gradually decreasing towards the upper square (Fig. 5). The lower end of the cross member 3 abuts against special shoes 6 (Fig. 5) or protrusions of the walls of the TOPKEY (Fig. 1), and the upper end is attached to the longitudinal beams 2, reinforced in the front and rear brick walls of the furnace (Fig. 1), or to the wall of the flame tube using SHEETS 5 AND 8

(Fig. 5). The lattices together with the beams 2 form the boxes for loading into them through the doors 15 (Fig. 7), fires, burned below under the squares 4, the riveted rollers of which between the cross-pieces 3 are cut off (Fig. 4); in order to more freely access fires to the flame. Combustion products are directed into the passage between beams 2. Combustion air is supplied through grate 1 (Figs. 1, 5 and 6) with small gaps, which is also a grate for holding loose bonfire particles and non-combusted residues.

In order to protect the beams 2 from burnout 1 and THEY are lined with refractory lining 9 (Fig. 1 and 5). The posting of the air introduced into the furnace is regulated by a device consisting of a metal strip 17 placed in the upper part of the furnace chamber and fastened to it by one end of the metal strip 17 (Fig. 5, 6, 7), the other end of which passes into the rack 19 with gear 21 mounted on shaft 22; on the latter, a gear wheel 20 is attached, which is coupled to the rack rail by a vertical THRUG 23 pivotally connected to a lever 24 mounted on the axis of the ash door 11. With the temperature in the furnace changing, the strip 17 is lengthened or shortened by means of

whether the transmission will be less and less open the door. The vertical section of the ha 23 is made up of two parts and can be extended or shortened by connecting 25 (Fig. 6 and 7), in order to adjust the normal opening of the ash door firebox. For monitoring the burning and for raking up the ash from the grate 1, the door 15 serves.

1. A fire burning furnace, characterized with the use of two gratings placed on the sides of the firebox, made up of each of the longitudinal gons 4 connected to the obliquely installed: cross-beams 3 (FIG.) Attached from above to the longitudinal beams 2 and supported from the bottom to the walls The fireboxes, which lattices together with these beams and walls, are formed by boxes for loading fires through the doors 15 (Fig. 7), which are burned from below under the squares 4 as the combustion products are directed into the passage between the beams 2.

2v In the furnace described in p. 1, the use of lattice 1 (Figs 1, 4, 5, 6) with four slits for air passage and holding the KOCTpk particles dumped, as well as unburned residues.

3. In the furnace described in clause 1, the use of refractory lining in beams 2, in order to protect them from burnout .-:

4f In the application described in p 1 of the furnace, for adjusting the air introduced into it, a device consisting of a metal strip 17 fixed to the top of the furnace kayer and fastened to it with one end of a metal strip 17 (Fig. 5, b, 7) With an ashpit door 11, for the sake of pain or less, opening it at measuring the length of strip 17 in connection with a change in temperature in the furnace.
