Description

The invention relates to the combustion of fuel and can be used in domestic stoves.

The aim of the invention is to increase the economy and simplify maintenance.

Fig. 1 depicts a firebox, an isometric sectional view of the individual parts; in fig. 2 is a top view of FIG. one; in fig. 3 shows section A-A in FIG. 2; in fig. A - node I in FIG. 2: in FIG. 5 is a view along arrow B in FIG. 2; in fig. 6 — node II in FIG. 3; in fig. 7 - funnel, general view; in fig. 8 is a section bb of FIG. 7

The furnace contains a cylindrical vertical combustion chamber 1 with a water jacket 2, as well as with central and ring loading hatches 3 and 4 placed in its lid 5, located under the lid 5 of the annular smoke box 6 with a suction window 7 and outlet nozzle 8 equipped with a gate 9, a horizontal grate 10 which is rotatably mounted in the chamber 1, with openings 11 for air and agitators 12, and a hollow cylindrical insert made of two parts 13 and 14. The lower part 13 of the insert is installed with the possibility of vertical It is equipped with lamps 15, which interact with the agitators 12 of the grid 10 and bimetallic petals 16, which form the bypass windows 17, and the upper end, having notches 18, inserted into the upper stationary part 14 of the assembly, equipped with an overflow window 19 and having a gate 20 which is mounted on the central hatch 3. and having a turn regulator, made in the form of a removable 2T knob with pins 22, inserted into the upper part 14 by inserts through holes 23 in the central hatch and interacting with the bottom 18 cutouts 18 STI

13 inserts. The suction window 7 of the smoke box 6 is made in the form of an annular slot with a variable height, increasing from the outlet nozzle 8 symmetrically on both sides of the box to its opposite side from the nozzle 8, and the gate 9 is provided with screw stops 24 and a regulator 25 made in the form of a bimetallic plate. Under the grate 10, an ash chamber 26 is placed, having a hatch 27. Water to the jacket 2 is provided with nozzles 28 and 29 of the water inlet and outlet. The insert forms in the chamber 1 an annular compartment 30, the upper part

14 inserts provided with a water jacket 31,

The furnace works as follows. Through hatch 2, fuel is charged to the grill 10, and through hatch 3 to inert material. Ignition and exit to the operating mode are made.i The flue gases produced during combustion are discharged from chamber 1 through smoke box 6 and window 7. During the burning process, a layer of fuel and inert material is punched by rotating the lower part 13 of the insert, which paws 16 rotates the grate 7. When shaking, slag and ash spill

0 through the openings 11 of the grill 10 into the ash chamber 26. The primary air for burning fuel enters through the openings 8.11 of the grill 10, and the secondary through the agitators 12. Part of the secondary air comes from

5 of the volume of the annular compartment 31 into the cavity of the lower part 13 of the insert through the bypass openings 17, Regulation of air flow into the cavity of the insert, and in some modes, the flue gases from the insert cavity into the annular compartment 31 are carried out by loops 16. The flue gases from the insert cavity are retracted through the overflow port 19. The flue gas exit from the insert cavity is controlled by the gate 20 with the help of the knob 21, In addition, the valve 21 rotates the lower part 13 of the insert. The heat in the furnace is regulated by a gate 9 placed in the pipe 8. When the temperature of the flue gases rises, the bimetallic regulator 25 gate 9

0 covers and vice versa. The maximum opening of the gate 9 is limited by the limiters 24, which are set to the required combustion mode.

Execution of suction window 7 flue

5 of the box 6 in the form of an annular gap with a variable height makes it possible to eliminate the aerodynamic sweep over the cross section of the furnace 1.
