Description

The invention relates to heating appliances used in domestic conditions.

According to the main author. St. No. 434796 known device! for burning coal fines, made in the form of a hopper, in the lower part of which there is a feeder for supplying fuel, a boiler, a fan, a temperature regulator and tonka with a grate and a screwing bar, while the device contains a stove mounted above the boiler, and the temperature regulator contains a sensor, mounted on a hot water supply pipe and connected by an electric drive with a screwing bar, feeder and fan. fifteen

The purpose of the invention is the intensification of the combustion of coal fines.

This is achieved by the fact that the proposed device is equipped with an additional grate, located under the stove, 20 and a manifold for supplying air under it.

In FIG. 1 shows the proposed device, a General view; in FIG. 2 is the same side view.

The device consists of a boiler 1, main 25 grate 2, fan 3, hopper 4, feeder 5, screwing strap 6, electric motor 7, belt drive 8, worm gear 9, chain transmission 10, plate 11, oven 12, duct 13 with swivel damper 14 for directing hot gases to a stove or boiler. On the front wall 15 are located; the kindling door 16 And the door 17 for removing toxins and the thermostat 18 for hot water, consisting of a sensor connected by means of ³³ electric drives with a screwing bar, feeder and fan. In the lower part of the device there is a slag receiver 19. In the upper part under the stove there is an additional grate 20 with a collector 21 for supplying air under it.

The proposed device for burning coal fines works as follows.

Coal fines (class 0-6 mm) from the hopper 4 with the help of a feeder 5 are fed to an additional grate 20, where air is supplied through the manifold 21 of the fan 3, the pressure of which is regulated depending on the characteristics of the fines; burnt slag shuruyu. with a lath 6 is discharged into the slag receiver 19. Hot gases are sent either only to heat water in the boiler 1, or under the stove 11 and the oven 12 for cooking. This is achieved by dividing the gas duct 13 into two parts by a rotary damper 14. In the case when only water heating is required, hot gases are sent through the lower part of the gas duct in automatic mode, depending on the set temperature of the water heating. The required degree of water heating is provided by an automatic temperature controller 18, containing a sensor mounted on a hot water pipeline and connected by an electric drive with a screwing bar, feeder 5 and fan 3.

When the set temperature is reached, the engine shuts off, stopping all mechanisms. When the temperature drops below the set value, the engine turns on. The operation of the fan 3, the drum feeder 5 and the screwing bar 6 is carried out from a single electric motor ’7 with a power of 180 W with a speed of 1440 rpm.
