Description

Patent No. 904 describes a Russian stove with a stove and smoke turns, the hearth of which has the appearance of a closed chamber with brick walls and a vault communicating through the view with the ascending exhaust duct and provided with doors on the side of the stove. The hearth is located above the chamber of the Russian stove, which serves as its firebox and has brick grate near its mouth with an under them blowing box containing the ash box, and smoke turns are placed: horizontal on the sides and behind the hearth, and vertical on the upper part of the furnace .

The present invention is a modification of the designated furnace and consists in 1) that a special firebox was made under the furnace of the Russian furnace, 2) that part of the hearth was occupied by a stove with two grid stoves replacing the grate bars, 3) that in the vertical chimney In the saw blade of the Russian furnace, a reversing flap was installed with a water tank placed above it.

In the drawing of FIG. 1 shows a schematic section of a furnace along AB in FIGS. 5, 6, 7, 8, and 9; FIG. 2 is the same for BG on the same figures; FIG. 3-cut oven for ME

in fig. 5, 6, 7, 8 and 9; FIG. 4 - the same for ZHZ on the same figures; FIG. 5 is a section along I-I in FIG. 1, 2, 3, and 4; FIG. 6 is the same according to 11-11 in FIG. 1,2, 3 and 4; FIG. 7 - the same as III - 111 in FIG. 1, 2, 3, and 4; FIG. 8 is the same according to IV-IV in FIG. 1, 2, 3, and 4; FIG. 9 - Same as V-V in FIG. 1, 2, 3, and 4; FIG. 10 - general view of the burner; FIG. 11 - installation of a brass plate in the rear part of the furnace under the bottom of the firebox in the section along the SH in FIG. 5, b, 7, 8, 9 and 12; FIG. 12 is the same in section along I - 1 in FIG. 1, 2, 3, 4 and 11; FIG. 13 movable bolt.

The design and operation of the furnace, generally similar to those described in patent No. 904, is that the firebox 1 is placed in the front of the furnace under the furnace 6. The Russian furnace and is blocked by a stove 2 with two grid burners 3 replacing the grate bars (Fig. 1, 3, 4, 5, 6 and 10). The fuel, which is burned in the firebox 1, incandescence first of the stove 2, in which cooking utensils can be placed in the openings of the burners. The air approaches the fuel through a blower with a hermetic door, placed, for the convenience of grate positioning and strength, on the side of the firebox (Fig. 3). The products of combustion from the firebox first enter the horizontal channel going under

with the furnace 6, on the side and behind it, then goes to the vertical channel located in the saws of the Russian furnace, and the pit passes through the flap 4 into the common chimneys of the Russian lechi, washing the tank 5 with water on its way (Fig. 2 and 8 ). The valve 4 closes with the same cap: during the firebox of the firebox - the chimneys of the Russian stove, and during the firebox and the Russian stoves of the firebox and has two frames connected by hinges to which the double-sided cap is attached simultaneously. One of the frames is wiped into the chimney of the Russian stove, and the other into the chimney of the firebox. The closing and opening of the cap takes place by means of a handle (Fig. 2 and 7), and the same zasponka closes the chimney of the Russian stove after its heating to keep the heat in the firebox (which is important when baking). If there are two cooking holes in the stove 2, if necessary, they can be tightly closed with ordinary burners, and during breadmaking it is necessary. The furnace b, covered with a plate 7, has, as already mentioned above, in the front part, along with the bottom plate 2, two lattice burners (Fig. 13) are inserted into the holes otor, in order to supply air to the fuel, (Fig. 13) They play the role of ordinary grates and under which the existing firebox 1, during the stoking of the Russian stove, plays the role of its blew. A chamber 8 with brick walls and an overlap that serves to cook food during the stoking of a Russian stove, separated from the furnace b by stove 7, is reported in case of gas occurrence with an upward exhaust channel closed by a slide valve over which this channel is connected channel samovar dehummer {Fig. one). Combustion products from the furnace b through two holes first enter the horizontal channel; then, through the flap 4, they enter the channel going to the sawing deck, wash the water-heating tank 5 and then with the vertical channel lift up to shut off the furnace and lower it

a narrow and long channel located in the side of the furnace, from where it passes into an outlet pipe equipped with a view. In order for hot gases not to heat all smoke exhausts in the summer, they can pass through the water tank 5 directly to the outlet pipe, for which purpose it is necessary to open the valve 9, which is closed during the cold season (Fig. 2).

In wood burner b, both wood and mineral fuels can burn, and during baking, the remaining unburned coal, together with ash and slag, is swept clean and goes down through the holes of the burners of stove 2 into the firebox. closed at the time of stoking the Russian stove with the flap cap 4, opens and the hood is turned over to the canal side of the Russian stove, where the hood with the help of the retracted movable bolt (fig. 13) embedded in the stove lay and Flap 4 (Fig. 2 a schematic view point) only poluzakryvaets, thereby stretching gases obtained from both the firebox. The same bolt can be used when gases appear in the furnace b when cooking food on the stove 2. At the end of the ashes of 6 ash from the furnace, the movable bolt from the chimney is pulled out and the holes of the stoves are tightly closed with ordinary burners.

The subject of the patent.
