SU63912A3 - Combined stove for space heating and cooking - Google Patents

Description

The invention relates to combination ovens used for cooking and heating rooms, equipped with ovens and hot water kettles having a through-flow tube. This kind of furnace is usually divided by height into two rusas with the heating of the first and then the second rus from the firelighter installed in the first rus. In both heating and combination furnaces, gas ducts are used for internal circulation of gases at the end of the furnace by shutting off the flue gas and opening the corresponding valves to provide circular communication of the gas ducts. In the proposed furnace, for the connection of the gas flues of the first and second Rus, the heating tubes of hot water boilers are used. The same pipes are equipped with gate valves and grates to allow the use of the kettles themselves when the furnace is not working.

In FIG. 1 is a front view of the furnace, FIG. 2 is its side view; FIG. 3 is a sectional view through 1-1 in FIG. 12, FIG. 4 - the same according to 2-2 in FIG. 12, FIG. 5 - the same according to 3-3 in FIG. 12, FIG. b - the same in 4-4 in FIG. 12, FIG. 7 - the same in 5-5 in FIG. 12, FIG. 8 through 24 — horizontal sections of the furnace along the respective horizontal rows of masonry bricks; and FIG. 25 is a perspective view of a pot.

The proposed combined stove for space heating and cooking is equipped with a stove and three ovens, two hot water boilers with flue pipes, and a system of valves for the internal circulation of gases at the end of the firebox.

Coal, firewood, peat, straw can be used as fuel for the stove. The furnace is divided into two Rousses, in the lower of which there is a firebox 6 with ashpit 2. Gases from the firebox pass through the threshold into the pass channel 13 and through the vertical channel 8 pass into the lower one equipped with cleansing 1, 1 collection 3, from which along the vertical channel 5

the transition to the upper Russian of the furnace, separated by the oT-i-nyzhiye rusa plate 24. On the channel adjacent to the channel 5, 12 basins;. move to a horizontal collection 12, 12 (Fig. 18), transfer to. the other side of the furnace, gas ducts 15, 16, 17 are successively carried out, a collection of 18 and - exhaust into the smoke: a new pipe 19. On .: .. our way; from .fuel to the chimney gases wash ovens 7, 25 ,. 31, installed one above the other and provided with doors 9, 4, 21, respectively. Hot water boilers 22, 23 located at U; on the sides of the oven 25, there are flame tubes 11, 14, fitted with gates 20, 26. To enable self-use of the kettles when the stove is not working, grates 33 are located in the flame tubes 11, 14, on which coal or other can be laid through the doors 34, 35 fuel.

After the end of the furnace and the closure of the pipe, the direction of the gas flow changes and the gases pass from channel 8 through the flame tube 14 to the collector 18, from which channels 17, 16, 15, 12 are lowered, the flame tube 11 to channel 5 and again rise to channel 8, flame tube 14, etc.

Thus, intrafig happens. one

Renn gas circulation in the common duct system at the end of the firebox. To induce this circulation may | hot air from the oven, 25, is also used, which, when the doors 34, 35 are open, enters the common system of furnace gas ducts.

Patent Subject

Claims (2)

1. A combined stove for space heating and cooking, with several ovens and hot water kettles, fitted with flue pipes, divided in height into two series heated races, with: The possibilities of using a common gas duct system for internal circulation of gases after the end of the furnace, which differs from that for establishing the connection between the first and second Rus gas duct systems in order to ensure internal circulation of gases after the firebox, heat pipes I, 14 hot water boilers are used. 2. The furnace according to claim 1, characterized by the use of gate valves 20, 26 and grates 33 installed in the flame tubes of the kettles to enable the latter to be used independently when the furnace is not operating.
