Description

For the purpose of better utilization of heat, a modification of the furnace described in the patent of the same author for No. 812, consisting in a combination of an English hearth (a stove with a burner) and a Russian stove, which, in this case, plays the role of a thermos that accumulates heat for dovarki food. The proposed stove is designed for heating its coal. FIG. 1 furnace is shown in longitudinal section; in fig. 2 is a transverse vertical section along line I-I of FIG. 1, for the firebox; in fig. 3- in a transverse vertical section along the line P-II of FIG. 1, through the cooking chamber; in fig. 4 is a transverse vertical section along the line IV-IV of FIG. 1, on departure; in fig. 5 is a horizontal section along the line V-V of FIG. 1, through the cooking chamber; in fig. 6 in the same section along the line VI-VI, the onion cupboard and the grate and in FIG. 7, 8-vertical and horizontal section of the furnace in which the products of combustion do not enter the cooking chamber. The furnace consists of a quadrangular, in the form of a well, a firebox and with a grate grating plates e, e, e, which are installed so that the bottom plate e lies, as usual, horizontal, and the other two plates e, obliquely on the sides (Fig. 2) and with one edge rests on slab e, a. other, bent, on the side of the firebox. All three plates are equipped with holes for irochola in the air furnace. The firebox and is covered with a stove And, having two burners And, H1. Under the stove I, you can find, as usual, a fire b, a boiler and a slider, thanks to which you can turn off the oven and the boil from the scope. A space P is left between the powder puff and the boiler, protected from above by a pig-iron square P, above the stove. A brick cooking chamber D of the Russian stove is arranged, into which hot gas flows directly from the back wall through the windows D engine g, or after irohod.a. around the oven {b and kettle). The products of combustion from chamber D are removed through channel D, placed in the front of the furnace above the oven; Channel D, with the valve open, e, is directly connected to the chimney, while the valve is closed, the combustion products are directed to the overhead heating space, e, from which downstream, located between the double walls of chamber D, wells W) K (Fig. 2, 3 and 5) flow along two ascending chimneys K (Fig. 4) into pipe I, closing with a valve / f. Chamber D is equipped with two doors, internal x and external f. Under the oven and boiler, for isolation, air chambers are made. Chamber D can also be arranged so that the combustion products will not get into it, and directly from the firebox with the valve L open, they will be directed (Fig. 7) along the channel Y, directly into the pipe; or the flame from the firebox a, having rounded the oven and the boiler, is sent to two flame ascending channels Ж, ж (Fig. 8), connected to the fire chambers e, e, of which are located between the bottom wells The walls of chamber D are passed through two ascending chimneys K and then through pipe K to the outside. SUBJECT OF THE PATENT. Modification of the furnace described in patent No. 812, characterized in that instead of a cusp plate, a flat stove was used And with burners //, the outflow of gas from the cooking chamber D was made not in the vault of the latter, but in its front wall There are no bars from the space between the double doors of the eyeliner, and the lower part of the furnace, behind the firebox a, is used to place the oven baffle and the hot water boiler in, to direct the flue gases from under the stove to the valve
