Description

The utility model relates to heat engineering, namely domestic stoves, and can be used for individual saunas and baths, heating various rooms and heating water.

The well-known "Combined stove-heater" RU 85610 [2], the steel walls of which are double with the formation of a space between them, acting as a water tank, containing a firebox with a vault and a grate, located above the vault of a firebox a heat-loading heater, located under the grate the grate is an ash pan, a chimney, and a gap is made between the heat-accumulating loading stove and the furnace walls, the furnace is made in the form of a volumetric metal structure, has two gas ducts located under loakkumuliruyuschey loading horizontally and parallel to each other and the side walls of the furnace.

The disadvantage of this device is the low heating rate of the room, due to the low temperature of the outer walls. The disadvantage is the low efficiency of vaporization, due to the selection of heat from the stones of the heat storage load adjacent to the tank with water, the temperature of which is less than 100 °. The disadvantage is the inability to adjust the operating mode of the furnace.

The closest technical solution is the “Geyser bathhouse furnace and steam superheating method” RU 2250417 [1], comprising a metal housing with a furnace, a water tank with a chimney and a pressure vessel with a heat-exchange coarse material and a moisture distribution installed in its upper part a device connected to the tank for vaporizing liquid by means of a dispenser and an outlet steam line.

The device has an increased vaporization efficiency compared to [2] due to the heating of the tank with heat storage load from all sides.

The disadvantages are the increased dimensions of the furnace, low heating rate of the room, the inability to adjust the operating mode of the furnace.

The technical result of the invention is to reduce the size, increase the heating rate of the room and the possibility of adjusting the operating mode of the furnace.

The technical result is achieved by the fact that the solid fuel bath furnace containing a metal body with a furnace, chimney, a water tank with a chimney pipe and a container (high pressure) with heat exchange (coarse) material and a moisture distributing device installed in its upper part connected to the steam generating tank liquid by means of a dispenser and an outlet steam line, characterized in that a channel for flue gases is located between the body and the pressure vessel, in the upper part of the channel false collector connected to one input of a tee-channel switch with a movable gate, the other input is connected to the upper part of the pipe passing through the water tank, and the outlet channels tee switch connected to the chimney.

Part of the housing opposite the heater, facing the heated room, can be made of a radial shape. The specified implementation will further improve the heat transfer by radiation of the housing into the heated room. Due to the radial shape of the furnace body, heat is evenly dispersed in the room. Also, the shape of the furnace contributes to its durability, since the radial shape is less subjected to deformation from heat.

The furnace may contain rotary grates, which allow to intensify the combustion of fuel due to faster removal of ash from the surface of the pieces of fuel.

The tee may have a removable cover connected, for example, by means of a flange connection. The presence of the cover will allow for the cleaning of chimneys from soot.

The outlet steam line may be located at the bottom of the heater. The indicated location of the steam line will allow you to effectively heat the shelf for the steam worker, usually located in height near the middle of the height of the steam room. In addition, it is possible to connect a pipe to the steam line, with which steam can be sent to any place in the bathhouse.

The device is schematically shown in FIG. 1 (longitudinal section), FIG. 2 (horizontal section along the top of the tank and tank), where

1 - housing;

2 - firebox;

3 - chimney pipe;

4 - a tank for water;

5 - capacity for heat exchange material;

6 - moisture distribution device;

7 - output steam line;

8 - channel for flue gases;

9 - collector;

10 - tee-switch channels;

11 - chimney;

12 - tee cover;

13 - rotary grates with handles;

14 - movable damper.

The device operates as follows. In the housing 1 there is a furnace 2 and a chimney 3 passing through the water tank 4. The container for the heat exchange material 5 is equipped with a moisture distributing device 6 in the upper part, for example, in the form of a tube with holes connected to a moisture feeder (not shown ) and the outlet steam line 7. Outside, the tank for the heat exchange material 5 is heated by the flue gases passing through the channel for the flue gases 8. The flue gases are collected in the manifold 9 and approach one input of the tee switch the bulk 10 with a movable shutter 14. The upper part of the chimney 3 is suitable for the other input of the tee-switch of channels 10. The tee-switch is equipped with a cover 12 for routine maintenance - cleaning the chimney, checking the draft, etc. The tee switch can be connected to pipes on flanged joints, which will greatly simplify transportation, installation and maintenance. The furnace can be equipped with rotary grates 13 to optimize the combustion mode of fuel and simplify the discharge of slag.

In the position of the regulator flap that blocks the chimney that passes through the hot water tank, the draft is guided through the heater and the heat-reflecting area of the furnace. As a result, the stove gives more heat and dry hot steam to the bathhouse. In the position of the regulator flap, overlapping the chimney, which passes through the heater and heat-reflecting area, the draft is directed through the tank with water. As a result, the water heats up quickly, and the stove gives less heat to the bath room, which allows the consumer to wash comfortably, avoiding unnecessary stress on the heart. On the tee-regulator, the damper positions are provided, which allow heating the water and the heater in equal or different proportions. This allows the consumer to choose the best modes for themselves, depending on the bath room, climate and personal preferences.

EFFECT: reduced dimensions are achieved by a layout that allows two chimneys to be run in parallel - one through a heater, the other through a tank with a switch in the upper part of the furnace.

The technical result is an increase in the heating rate of the room is achieved by organizing a channel for flue gases passing directly behind the outer wall, which leads to rapid heating of the outer wall of the furnace.

EFFECT: possibility of adjusting the operating mode of the furnace is achieved by the presence of a tee, which allows, if necessary, to separately heat the room and heat storage load and separately heat water. This allows the consumer to choose the best modes for themselves, depending on the bath room, climate and personal preferences.

Industrial application.

The utility model can be successfully applied for the production and operation of bath furnaces with increased efficiency.
