Description

one

The invention relates to the area of combustion and 3 industrial sawn and heating boilers can be used.

The aim of the invention is to improve the economy by reducing underburning.

Fig. 1 shows a device for burning coal fines, a longitudinal section; in fig. 2 - section A-A in FIG. 1 ;, on. FIG. 3 is a section BB in FIG. 2; in fig. 4 - section BB in FIG. 3.

The device for burning 11 and coal fines contains a furnace 1 with water-cooled walls 2 and a rotating grate 3j connected. with a firebox 1 hopper 4, equipped with a feeder 5) and a fan 6, the grate 3 is made in the form of an inclined cylindrical helix having end rings 7 and 8 interacting with a drive mechanism 9 having support and drive rollers 10 and 1 G. .

The drive mechanism 9 of the grille 3 and the fan 6: are connected to the engine 12, the axis of rotation of the grate KJP 3 is inclined towards the window 13 to unload the donkey into the pallet 14.

The feeder 5 is made in the form of a rotating drum with funnel-shaped cells 15 on its surface. The feeder 5 is mounted on the axis 16, which is connected with the drive shaft 1 7 with a neve-nmii-, face ring M 7 of the grill 3. The furnace 1 is equipped with a loading door 18, a cleaning hatch 19, an exit window 20 and heat exchange pipes 21,

The device works as follows.

Pre-moistened with water, the coal in the cassette is loaded into the hopper 4, the ignition of the furnace is stopped

426812

Through the door 18, in the process, chips and firewood are placed in the firebox 1, which fits. After the wood has burst on them through the door 18

5 threw coal, and after ignition of this coal, the driving motor 12 is turned on, which by means of the fan 6 supplies air to the furnace 1, as well as through the driving mechanism 9 and

10 drive rollers 11 rotates the grate 3. The grate through the end ring 7 and the drive wheel I7 transfers the rotation to the feeder 5, which is located inside

15 furnaces above the burning zone. The drum of the feeder 5 is provided with axial boom and articulated cells 15 extending to the periphery of the drum 5. As the drum 5 rotates, the coal fines

20 is pressed by the walls of the cells 15 and the rear inclined wall of the bunker 4 and is partially sintered, since the feeder 5 is heated during operation of the device. So coal

25 trifle is delivered to the firebox G in the form of condensed and sintered portions,.

The coarse grate 3 rotates during the burning process, which allows efficient shoveling

jg the coal and move the burning coal along the inclined axis of rotation to the window 13. The velocity of the penetration grid 3, its length, pitch and number of windings of the helix are chosen so as to be unloaded.

 the coal is completely burnt and only ash is removed to the pan 14. The rotational speed of the feeder 5 is consistent with the coal burned speed so that the required amount of heat is in the furnace 1 all the time and the right amount of fuel is supplied by the feeder 3. The device works in the automatic mode, in this case it is only necessary to timely fill the bun 4 with coal and clean the pallet 14.
