Description

The invention relates to heating furnaces, in the lower part of which the firebox is placed, and in the upper part - a system of parallel or similar gas ducts, between the knees of which there are air-heating chambers or channels. The latter are connected with the heated room through the upper collector and the lower air-heating chamber, which has a metal under, which is the roof of the firebox. In the proposed furnace, it is possible to use an air heating system of channels and a chamber for internal circulation of gases after the end of the furnace, which should contribute to the uniform heat transfer of the furnace. In order to establish a circular connection of channels and to ensure the circulation of gases under the lower air-heating chamber, it is made retractable, and the extreme ventral channels are connected independently to a heated room using box-chambers washed with exhaust gases. The latter are equipped, each, with several windows, the part of which serves to pass

air into the air-heating system during normal operation of the furnace, and partly for the passage of gases from the air-heating channels to the gas ducts of the hotplate when the air-heating system is operated for gas circulation:

Regarding the method of heating, the proposed furnace is made in the form of a semi-gas furnace known per se with a gas generator type firebox: having a double light air supply through channels located in the walls of the firebox with vertical gaps along the firebox perimeter.

In the schematic drawing of FIG. 1 is a front view of the furnace; FIG. 2 is a vertical section through it of 2-2 in FIG. ten; FIG. 3- the same as 3-3 in FIG. ten; fig .; 4 is the same according to I - 1 in FIG. ten; FIG. 5, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 - horizontal sections of the furnace along the respective masonry rows; FIG. 6 and 18; - perspective view of the firebox with the supply of primary and secondary air; FIG. 21 and 22 is a perspective view of the camcorp.

At the bottom of the stove is placed

todaivnik gas generator type, which can work not only on coal or wood, but also on peat, straw, etc.

In the lower part of the furnace (there is a firebox 4 with a grate 37, under which there is an ashpit 15, closed by door 1. Around the firebox there are air channels 2, 2 communicating with outside air in the first river through windows 3, 23 and in the second trough through windows 38, 38. The walls of the firebox are provided with vertical slots 35, 35 for introducing and uniform distribution of air in the fuel layer.The arch of the furnace is made of two metal plates 24.25, from which plate 24 can be extended to establish a connection between firebox .4 and lower air heater Noah chamber 18. From furnace 4, gases pass along channels 5, 6 located near the furnace walls, washing chamber-box 7 (Fig. I, 21, 22), and poured along a row of parallel ascending gas ducts placed in the upper part of the furnace 9 9, joined by a collecting chamber 19 adjacent to a chimney 21. There, also between air ducts 9.9, are located air ducts 10, 22, 10, combined at the top by a collector 12. The central channel 22 communicates with the lower chamber 18. Side channels 10, 10 are connected independently with a heated room through channels 17 and chamber boxes 7.

Placed in the ducts of the box 7 is equipped with Windows 20, 27, 36 and gates 14. With the appropriate switching of the hooks 14 through the windows 20, 27, the air passes into the channels 17, .10 and further into the air-heating system, from which hot air enters the room through the doors at the top of the stove. When the windows 20, 36 are open, a connection is established between the gas ducts of the furnace (firebox) and the ducts 10 of the air heating system.

For operation of the stove - Fuel, stove -. . It is supplied to the furnace 4 through the chamber 18 Yri with an open plate 24. Heating is performed in the usual way with the possibility of using an air heating system supplied with air through windows 20, 27: boxes 7. After the burning of the fuel, the plate 24 again moves forward and the spiders 14 switch, resulting in hot the gases from the furnace through chamber 18, as well as channel 22, enter collection 12, descend through channels 10, 10 into boxes 7 and, with open slides 14, 14, again get through channels 6 into the furnace.

Patent Subject

A heating stove with a firebox connected to a system of parallel ducts directed from the periphery to the center and separated from each other by vertical flat air ducts communicating with a heated room by an upper collector and a lower air-heating chamber provided with a metal hearth, that, in order to use the air heating system of channels and the chamber for internal circulation of gases at the end of the furnace, under the lower air heating chamber 18 the retractable air vents are not retractable, and the extreme air ducts 10,10 are connected independently with a heated room using chamber boxes 7, 7, surrounded by gas ducts 5, 6 adjacent to the firebox and equipped with windows 20, 27, 36, of which windows 20, 27 serve for the passage of air into the air-heating system during normal operation of the furnace and the window 20, 36 — for the passage of gases from the channels 10 to the gas ducts during the operation of the air-heating system for gas circulation.
