Abstract

FIELD: heating.

SUBSTANCE: fire place of a stone stove is made in the form of a diffuser so that a turbulent flow can be formed in it. Flue gas duct 2 is passed via thermal bus 4 for heating of stones 5 without any direct contact of combustion products to them and is of a turning type at gas outlet. Control draft damper 6 is installed in stack 3 6. A stove includes convective air pipes 9, 10, at the outlet of which a provision is made for a turbulent air flow under the thermal bus for efficient heat exchange and reduction of heating time of a room. The stove allows heating using both firewood, and an atmospheric diffusion gas burner.

EFFECT: creation of a stone stove of a simple design, which is appropriate to the material, and which ensures increased thermal efficiency and ecological standards at its operation.

Description

The invention relates to heat engineering and can be used in the equipment of individual or personal baths for heating, water heating and steam supply.

Many stove furnaces are known, of which:

- devices [1. Shepelev A.M. How to build a rural house. - M .: Rosselkhozizdat, 1984. - S. 390; 2. Kolevatov V.M. Stoves and fireplaces: Description, construction manual, working drawings. - St. Petersburg: Diamond, Golden Age, 1999. - S. 270-306; 3. Pat. RU No. 2039324, IPC6, F24B 1/18. The method of heating the sauna stove-heater and the sauna stove-heater. Published on July 9, 1995], selected as analogues, have significant shortcomings in service, create discomfort when using them: it is possible to deposit soot on stones, and steam pollution with it. In addition, the furnace [1; 2; 3] have significant inertia during melting and low efficiency (COP);

- devices [4. The Hekla stove. Business-class wood-burning stove // Thermofor. Siberian stoves, boilers and fireplaces: Catalog. - [b.m.]: LLC Termofor, 2010-2011. - S. 36-37; 5. Heating bath stoves: Catalog. - [b.m.]: Ermak-Thermo Company, 2010. - 18 s], also selected as analogues, have an aesthetic appearance and hygienically comfortable conditions for users. During their operation, an accelerated heating of the room occurs due to the use of metal as the main material of the furnace design. But at the same time, the efficiency of the furnace is reduced, in a small-sized bell-type furnace with atmospheric diffusion combustion, the first flame cone touches the design of the furnace, resulting in reduced combustion, and in the exhaust gases the CO content and the amount of soot are increased, which reduces the efficiency (efficiency) of the furnace and worsens ecology;

- the closest device adopted as a prototype is a convection flame furnace [6. Pat. Utility Model RU 103173, U1, IPC F24B 5/00 (2006.01) Convection Flame Furnace / Ryabov DB declared 03/09/2010, publ. 03/27/2011.], Which has the same drawbacks as its counterparts, and also does not have the ability to control the combustion process. The aim of the invention is to create a simple, technologically advanced design of a stove-heater, providing increased thermal efficiency, environmental standards during its operation, eliminating the disadvantages of analogues and prototype, while maintaining their positive qualities.

The achievement of this goal is achieved by the fact that the furnace is made in the form of a diffuser with the possibility of the formation of a turbulent flow of combustion products in it. The furnace is supplemented by a chimney passed through a thermal niche for heating stones without direct contact of the combustion products with them and made rotary at the gas outlet, and a control damper is installed in the chimney. A turbulent air flow is provided at the exit of the air convection pipes for the efficiency of heat transfer and reduction of the room heating time.

The invention is illustrated by drawings, where in FIG. 1 shows a stove-furnace containing a furnace 1 with a chimney 2 and a chimney 3, a heat niche 4 for stones 5, a draft control damper 6 in the chimney 3, a loading and shovel door 7 with thermal glass 8, convective air pipes 9, 10, shutters 11 on the door 7, grates 12, the soot cleaning hatch 13, ash pan 14.

In FIG. 2 is an axonometric view illustrating an embodiment of the furnace.

In FIG. 3, 4 indicate the installation of the furnace.

The proposed stove-stove eliminates the disadvantages of furnaces of existing structures due to the formation of a turbulent flow of combustion products in the diffuser path of the furnace, which provides a mixture of fuel (products of sublimation of firewood and air), close to stoichiometric combustion, and heat transfer efficiency (COP). The furnace is supplemented with a chimney 2, rotated and passed through the heat niche of the steam generator for heating stones without direct contact of the combustion products with them.

Along with this, the turbulence of the air leaving the convective air ducts also contributes to the efficiency of heat transfer and to reduce the time for heating the room.

The furnace can be manufactured using standard equipment and materials of domestic production. Thus, the claimed device meets the criterion of "industrial applicability".

The procedure for working with the furnace. Having put the firewood in the firebox 1 so that they do not interfere freely open and close the door 7, melt the firewood. After that, close door 7, and leave the shutters 11 on the door 7 in the ajar position, which ensures free, without soot burning of firewood with minimal traction, which is regulated by the shutters 11 on the door 7 and the shutter 6 on the chimney 3. When the firewood burns out, ensure optimal stability burning by adjusting the blinds 11 and the shutter 6. The sight glass 8 serves to control combustion, with low fire the glass is covered with soot, with strong - it cleans itself. To open and close door 7, a metal hook is used.

The furnace works as a stove with one turn in the chimney through a thermal niche without direct contact of the combustion products with the stones of the steam generator. Gases at the exit through a turn in the chimney provide a safe temperature level (100 ÷ 200 ° C), recommended by regulatory documentation, for example, GOST 20548 or others.

It is possible to use a furnace with a gas burner of atmospheric diffusion power of not more than 16 kW. At the same time, it is possible to use a furnace for hot water supply of the bath.
