Description

The utility model relates to furnace designs and can be used for bath equipment.

A known furnace (RF patent No. 2289069 class. F24B 13/00, 13/02), comprising a housing, a furnace, a grate, a smoke exhaust pipe, heat storage material laid between the furnace and the walls of the housing, a gas duct connected to the furnace and the chimney, a water heater, while the furnace has the shape of a truncated pyramid, and above the junction of the walls of the housing and the furnace there are openings for the entry and circulation of cold air through the heat storage material, and the water heater is made in the form of a pipe placed around the perimeter of the grate, on which the firebox is installed.

The disadvantages of the furnace are:

- not enough high heat transfer of the furnace, since the heat storage load is heated only from the ceiling and side walls of the furnace. Due to the small contact surface of the hot walls of the furnace with a heat storage load, the gases leave the furnace with a high temperature and are sent to the chimney. As a result of this, heat loss with flue gases is large and the furnace efficiency is low;

- high heat consumption to obtain the desired result;

- limitation of the functionality of the furnace.

Closest to the technical nature of the claimed is a furnace protected by RF patent No. 2385440 cells. P24B 1/02, which is adopted as a prototype. The furnace contains a housing, a furnace, a smoke exhaust pipe with a valve, chambers with a heat storage load located above the fire chamber, an ash pan with a grate, a gas duct passing along the perimeter of the body around the chambers, connected to chambers with a heat storage load and a fire chamber. The furnace contains an additional pipe installed in the furnace and in the opening of the chambers with a heat storage load and connecting the cavity below the furnace with a smoke exhaust pipe. The upper end of the additional pipe is located in the pipe for smoke removal below the valve level, and the valve of the pipe for smoke removal is made with the possibility of blocking the hole between the pipe for smoke removal and the additional pipe with the possibility of movement of flue gases when the valve is closed in the flue, cavity, additional pipe and pipe for smoke removal above gate valves.

The disadvantages of the furnace are:

- the heat transfer of the furnace is not high enough, since the heat-accumulating load is heated mainly due to the flow of hot gases after the valve is closed, passing through the gas duct made around the perimeter of the furnace body around the chambers, and the inner walls of the chambers are heated only when the smoke exhaust pipe warms up. Due to the small contact surface of the hot walls of the chambers with the heat storage load, the heat transfer of the furnace is reduced;

- high heat consumption to obtain the desired result;

- limited functionality of the furnace due to the lack of the possibility of heating the premises located on the side of the front wall of the housing;

- the inability to control the heat capacity of the furnace.

The objective of the utility model is to increase the heat output of the furnace, reduce fuel consumption and expand the functionality of the furnace.

This object is achieved in that in a furnace containing a body, a furnace with a grate, a smoke exhaust pipe, at least two chambers with a heat storage load, located above the fire chamber, a gas duct passing along the perimeter of the body around the chambers, connected to cameras with a heat storage load and a fire chamber , according to a utility model, heat storage chambers are separated by gas ducts connected to the firebox through slots formed by the walls of the casing and the bottom of the chambers in a smoke exhaust pipe in the divided zone channel channels are made slots; the side walls of the housing on three sides are made of two rows of sheet corrugated material interconnected so that they form vertical channels between themselves, and the cavities formed between the walls of the chambers and the corrugated walls of the housing are tightly closed from above; on the front wall of the casing in front of the furnace, a loading channel is made, which is surrounded by a hollow casing with holes for air inlet and outlet.

The air outlet openings have means for blocking them.

In addition, any of the three walls of the furnace body made of sheet corrugated material from the second row can be made movable: with the possibility of reciprocating movement in the horizontal direction or pivotally relative to the lower end of the wall of the body made of sheet corrugated material from the first row to form additional space for heat storage loading.

Figure 1 shows a General view of the furnace in a perspective view;

Figure 2 is a General view of the furnace in section;

Figure 4 - section of the furnace aa with extended side wall;

Figure 5 is a cross section of the furnace bb In figure 4;

Figure 6 is a cross section of the furnace bb In figure 4 (option with a reclining side wall).

The furnace contains (Fig. 1, Fig. 2) a housing 1, a firebox 2, a grate, a smoke exhaust pipe 3, chambers 4 with a heat storage load 5 located above the firebox. The furnace 2 is bounded below by a grate 6, under which an ash pan is located 7. A gas duct 8 is made around the chambers 4 around the chambers 4, connected to the chambers with a heat-insulating load and the furnace. The chambers 4 are separated by gas ducts 9 connected to the firebox through slots formed between the walls of the housing and the bottom 10 of the chambers 4 (Fig. 3). In the pipe for smoke removal 3 in the zone of the gas separation channels, slots 11 are made for the exit of gases, and the bottom hole of the pipe is blocked by the bottom of the chambers. The side walls of the casing on three sides are made of two rows of sheet corrugated material interconnected so that they form vertical channels with each other, and the cavities formed between the walls of the chambers and the corrugated walls of the casing are tightly closed from above.

On the front wall of the housing in front of the furnace, a loading channel 12 is made with a door 13, which is surrounded by a hollow casing 14 with openings 15 and 16 for air inlet and outlet. The air outlet openings have means for overlapping them, for example, with a plate (FIG. 2).

In order to create additional space for heat storage loading, any of the three walls of corrugated sheet material from the second row can be made movable: with the possibility of reciprocating movement in the horizontal direction (Fig. 4, Fig. 5), or hinged relative to the lower end of the housing wall from sheet corrugated material from the first row (Fig.6). The extension of the corrugated wall occurs simultaneously with the bottom of the additional capacity along the guides. On the side, the additional container can be closed, for example, with a metal mesh.

The furnace operates as follows.

In furnace 2, fuel is ignited, for example, firewood. Combustion products in the form of flue gases pass through slots formed by the bottom of the chambers 10 and the corrugated walls of the casing, entering the gas duct 8 passing along the perimeter of the casing around the chambers, heating the walls of the chambers facing the casing. Next, the flue gases pass into the gas ducts 9 separating the chambers, heating the chamber walls facing each other, increasing the heat transfer surface. Smoke removal occurs through slots 11 in the pipe 3. Heating of the steam room is significantly increased due to the second row of corrugated sheet material, forming longitudinal channels with the first row of corrugated walls of the housing, in which the incoming cold air is heated.

The combustion mode of the fuel is regulated by the extension of the ash box. The front wall of the furnace heats cold air, which enters the holes 15 located in the lower part of the front wall, and when heated, leaves the upper holes 16, regulated, for example, by the plate 17.

The advantages of the proposed furnace in comparison with the known are:

- increase the heat transfer of the furnace by increasing the ability to block the direct flow of hot flue gases into the pipe and create their movement around all the walls of the chambers with heat-storage loading,

- reduction of fuel consumption to obtain the desired result;

- expanding the functionality of the furnace due to the presence of a heated casing on the front panel of the furnace, which goes into the dressing room or other room for heating;

- the ability to control the heat capacity of the furnace by creating additional capacity for the heat storage load.
