Abstract

The appliance for solid fuel burning has loading chamber with fire-proof hearth as truncated cone turned downwards with the smaller base, with through channels connecting the bypass channel of air supply for primary oxidation of fuel to the over fire-bar section, the central vertically going down channel-chamber of afterburning of pyrolized gas and fuel particles connected to autonomous dozing chamber of air supply. The bypass channel of air supply is separated to autonomous bypass channels with controlled gates, with possibility of autonomous air supply in height of the hearth and provision of uniform gasification of fuel. Over the hearth bypass zone is placed, made of fire-proof material with through channels connecting the cavity of the over fire-bar section to the upper bypass channel for air supply, over the central channel-chamber extension element made of fire-proof material is installed. Such implementation of the unit provides possibility of complete burning of any solid fuel.

Description

The disadvantage of the prototype is the uneven gastor. A central fuel filter is placed under the grate above the grate space, channel-chamber 5 (Figs. 1, 2) is vertically directed, due to unregulated dispersion downwards, it is coaxial with the axis of grate 2. Channel-air supplied, along the height of the grate of the device, chamber 5 is made made of a heat-resistant material that contributes to the intensive burning of fuel in the upper part, for example, chamotte, and is intended for the extra palusion of the space above the grate. In the lower zone, the pyrolysis gas formed in the overburden, at the same time, is formed in the carbon-rich lozenge space and fuel particles, which is insufficient material - coal, which can lead to hovering. Above the channel-chamber 5, the charge is installed on the black. Air supply for afterburner - extension 6, made of heat-resistant material and pyrolysis gas in the channel-chamber, which is integral in height and perimeter. The protrusions 7 on the grooves in the space above the grille in the form of an extension 6 provide the formation of passages 8, 9, a continuous annular jet, it is not advisable, connecting the above-extension and the above-rail since there is no uniform mixing of the space with the cavity of the channel-chamber 5 for air-oxidizer with heated pyrolysis gas and flow of pyrolysis gas and ash. In the upper part of the fuel particles and, accordingly, the wall of the channel-chamber decreases, along its perimeter, a note of combustion of pyrolysis gas and fuel particles is made - channels-nozzle 10 (Fig. 1, 2), with the possibility of many. jet air supply from the dosing chamber 11,

The invention is faced with a task provided with an adjustable damper 12. To surround the uniform combustion in a separate channel 4 above the grill, for example, with the help of space and complete combustion of any solid annular partitions on autonomous channels 13 of fuel due to the adjustable distribution of supply by dampers 14 , 15, with the possibility of adjustable air flow along the height of the stem and multi-jet supply of oxidizing air along the height of the stem. A circumferential belt (Fig. 1, 4) of unburned fuel particles is installed above the air supply to the pyrolysis gas afterburning zone and the slag. of heat-resistant material with through windows 17, according to

The task is achieved by the fact that in the connecting space above the grate with the upper device for burning solid fuel, which is a circumferential air supply channel. A reflector 18 is placed under the channel, which contains a loading chamber with a heat-resistant chamber 5, providing a black in the form of a truncated cone, which reduces the movement of smoke along the heat exchanger 19. The chimney 20 is connected with a pipe 21, equipped with a smoke extractor, with a base directed downwards with channel openings us, connecting the circumferential air supply channel 22. for primary oxidation of the fuel from the grate - The extension can be made (Fig. 3) with a central space, the central vertical passages 8, formed by the elements of the cover directed down the channel-chamber afterburning extension 6 in in the form of petals 23, the radial depyrolysis gas and unburned fuel particles moved from the center of the extension, forming passages connected to the autonomous dosing chamber according to 8. Under the passages, an additional air supply lining is placed, according to the invention, a circumferential channel 24, protecting the spread of fuel in the channel-chamber 5 of the air supply is divided into independent circular ones (Fig. 1, 2). On the surface of the petals 23 there are arc-shaped channels with adjustable flaps, with the possibility of grooves 25, which together form helical, self-contained air supply along the height of the stem and deep grooves for improving the gasification process of uniform gasification of fuel, over gasification of fuel. a circular belt made of heat-resistant heat-resistant fuel is placed in the trunk. The combustion of solid fuel in the proposed material with through-channels connecting the covered installation takes place as follows. The rear of the space above the grate with the upper bed is ignited and heated by the extension 6 and the circumferential air supply channel above the central pallet 2 to a temperature of 6600-7000. It can be heated by a channel-chamber, an extension with flammable fuel, heat-resistant material with a covered top from deposits, dry shavings, firewood. The fuel is filled with fuel and coal, and with the passages connecting through the hatch (not shown in the figure) from above, the supra-supplementary and supra-grate pro-chamber 1 of fuel loading, while all rests with the cavity of the channel-chamber , at the top, the hinged flaps 12, 14, 15 are closed. The combustion of the wall of the wall, which has fuel channels along its perimeter, occurs due to the thrust of the smoke extractor 22, the nozzle, with the possibility of multi-jet supply, after burning, air is loaded into the chamber 1 and complete afterburning of pyrolysis gas and solid fuel intended for burning. After particles of unburned fuel. heating the shank and the extension open the

The device consists of a loading kado-firing. During the formation of hot coal, the measure 1 (Fig. 1), made of sheet metal, is placed over the attachment 6, which is a source of heating of the cylindrical shape and the heat-resistant shank 2 in the pyrolysis gas to a temperature of 1000-1100". A truncated cone with a smaller base , the ignition and combustion of gas is ensured in the kneecap downwards with through channels 3, connecting the losnikova and in the suprascapular spaces and into the circumferential channel 4 of the supply of oxidizer air for the channel-chamber 5. The regulated supply of the primary combustion of fuel over the grate is carried out - air at the height of the stem 2, through flaps 14, 15, behind

ensuring the burning of part of the coal and the maintenance of a sufficient volume of hot coal from the bottom of the coal layer, which is stable in height. temperature of 1100-1200"C, at which it occurs

If necessary, complete combustion of fuel into the formation of superheated steam and its decomposition in the central channel-chamber 5 and obtaining eco-hydrogen and oxygen. logically clean exit of smoke into the channel-chamber 5 according to The advantage of the proposed device for the spa-air-oxidizer is supplied multi-string for perilation of solid fuel in that due to the con-meter of the channel-chamber through the channels-nozzles 10, the centered - directed flow of pyrolysis ensuring high-quality mixing of pyrolysis gas from gas to the axis of the shaft in the central channel-chamber, with an oxidizer-air, increasing the intensity of maintaining a high temperature above the attachment for burning pyrolysis gas and small particles with a grate, by regulating the burning of unburned fuel. fuel and coal in those zones, favorable

In the proposed design of the device, conditions of actual complete combustion of solid fuel are possible for combustion of household waste with an environmentally friendly yield of fuel with a moisture content of up to 7095 due to stable combustion products.
