Description

In most room furnaces, the last passage to the pipe, through which the cooled combustion products, which gave off their heat, always has a common, most heated wall with a firebox or with the first ascent. The first lift is in most cases located inside the furnace and is completely isolated in terms of heat transfer from the living space that the chimney should service. The firelighter and the first move in such cases give up their heat only to their neighboring last run of the furnace, artificially raising the temperature of the gases leaving the tube. This is the main disadvantage of all furnaces of this type.

The proposed room furnace refers to brick furnaces of high heat capacity with a number of channels located at the rear wall for conducting gases from the firebox to the system of lifting and lowering ducts placed above the firebox. These ducts are located in separate pillars, which for air circulation are separated from each other by through openings and combined at the top and bottom by collecting chambers.

In order to increase the heat exchange surface between the lower collecting chamber of the flue system and the roof of the firebox, N1antsi are located, which are connected with the vertical air tubes of the furnace.

FIG. 1 shows the front view of the furnace; in fig. 2 - airborne side; in fig. 3 is a vertical section along the A-L in FIG. 5-9; in fig. 4-vertical slit on BB in the fig. 5-9; in fig. 5 is a horizontal section through / - / in FIG. 1 and 2; in fig. 6-9 - horizontal section, respectively, along the section m / 7 - //, /// - ///, / V- / 1 / and V-V.

The firelighter / furnace to increase the heat-receiving surface has protrusions-ribs 11. A threshold 12 is located along its rear side along the gases. In the front part of the firebox, there is a tag-9 stand for supplying air for fuel to support the front ends of the laid firewood. An air stream passing under the tangannik (under the fuel) upward for mixing with the combustion products is reflected by the threshold 12 in the underwater space. Underneath the threshold, in the back of the furnace, are the recesses 7, designed to increase the heat-giving surface of the furnace.

From the firebox, the gases along the parallel liftings of the ducts 2 rise to the upper part of the furnace and enter the annular collector 3, from which, through the system of parallel ducts 4, they are placed; In a separate pillar, they are lowered into the lower collection chamber 5. The latter is adjacent to the central tunnel in the furnace's exit discharge duct 6 connected to the chimney. Between the ducts 4, as well as around the duct 6, are located through 1p 1e openings 10, through which room air circulates, washing the outer surface of the ducts in the furnace. Over the arch of the firebox under the collecting chamber 5, grooves are located, which are connected with the openings JO and serve to increase the heating surface.
