Description

Technical field

The invention relates to a small power system and is intended for heating residential buildings, cottages and industrial premises.

State of the art

Known universal heat accumulating fireplace (patent RU 2402716, IPC F24B 1/18, publ. 10/27/2010), which contains a housing, firebox with a glazed refractory door, blown with grates, a duct smoke system connected to the chimney. It is equipped with a heat exchange and heat storage chamber located in the lower part of the fireplace and filled with heat-resistant material; a closing hole is made in the bottom of the blower, communicating with the heat exchange and heat storage chamber, as well as with the blower chamber; under the frame of the firebox door there is a gap for the passage of an adjustable amount of air from the room into the firebox. In the rear rear wall, along the edges of the lifting channel of the smoke circulation system, two convection channels are provided for the entry of cold air from below and the exit of heated air to the heated room at the top.

A disadvantage of the known device is its low efficiency, the fireplace warms up very slowly, as well as the complexity of repair and maintenance.

A known furnace made of refractory stone (application FI 102210, IPC F24B 1/02, publ. 10/30/1998), which includes a housing, firebox, in the form of a lined fireplace insert, with a glazed door, a chimney system, a remote chimney connected to the drainage channels from the back of the fireplace. Between the inner casing and the lining are air ducts.

The closest technical solution adopted for the prototype of the invention is a fireplace (hpp: // http: //tulikivi-russia.ru), which includes a body made of sawn bricks made of slate, a firebox with a glazed door, a chimney system, remote a chimney connected to the drain channels from the rear bottom of the fireplace. Between the outer wall of the housing and the cladding is insulation.

The disadvantage of these devices is low efficiency, namely slow heating, i.e. this stove of the second day, as well as the presence of condensate and only firewood is used as fuel.

SUMMARY OF THE INVENTION

The main technical objective of the proposed solution is to create a fireplace stove with high heat dissipation, retaining heat for a long time and easy to maintain and repair.

The main technical result is an increase in efficiency and a decrease in heating time, as well as a decrease in the formation of condensate in the device.

The main technical result is achieved by the fact that in the convection-accumulating stove-fireplace, containing a body made of talcum chloride, a firebox with a glazed refractory door, a duct smoke system connected to the chimney, according to the proposed solution, the firebox is made in the form of a metal furnace insert installed in convection niche, in the roof of which a hole is made for connecting the furnace insert, and in the roof of the distribution channel, a hole is provided with a valve The upper channels of the smoke system are lined with non-condensing material from the inside.

In addition, it is advisable to use chamotte as a non-condensing material.

Brief Description of the Drawings

The invention is illustrated by drawings, where in Fig.1 shows a front view of the device, Fig.2 is a General view of the device, Fig.3 is a section aa (Fig.1), Fig.4 is a section bb (Fig.1 )

DETAILED DESCRIPTION OF THE INVENTION

The fireplace stove consists of a housing 1 made of talchochlorite. In the housing 1 there is a metal furnace insert 2 inserted into the convection niche 3. The convection channel 4 is formed by the gap between the furnace insert 2 and the inner walls 5 of the housing 1. In the roof 6 of the convection niche 3, a hole 7 is made for connecting the furnace insert 2. Overlap 8 of the distribution channel made with a hole 9 provided with a valve 10, and the connecting channel is provided with a continuous overlap 11. The lining 12 of the smoke channels of the smoke circulation system is made of non-condensing material. An insulating layer 13 is laid on the lower base of the housing. On one side of the housing there is a hole 14 for cleaning.

On the rear wall of the convection niche 3, in its lower part, there is an opening for convection air inlet, and in the upper part of the niche there is an opening for the exit of already heated convection gas.

The device operates as follows.

The furnace insert allows you to use any type of fuel, namely firewood, coal, pellets, peat. The fireplace stove is flooded with the valve 10 open, after 15-20 minutes the valve 10 is closed and the gas flow does not begin to go directly, but through the revolutions (Fig. 1) through the smoke channels, heating the body 1 of the fireplace stove. Flue gases enter the chimney 10 chilled by 15-30%, giving energy to convection, due to the convection niche 3.

The proposed solution allows you to heat buildings from sub-zero temperatures to comfortable ones in 2-3 hours, while intense heat transfer starts 15-20 minutes after flooding, and uniform heat transfer takes place over 12-24 hours. In addition, the valve 10 allows to achieve rapid heating of the chimney, which eliminates the formation of condensate in the chimney, and, as a consequence, coking.

An increase in the efficiency of the proposed device is achieved due to a powerful up to 30% heat intake for convection and up to 70% for accumulation, which allows to obtain a temperature of flue gases at the fireplace exit 70-120%. Lining the chimneys with ceramic tiles eliminates the formation of condensate directly in the furnace, especially at the beginning of the heating process.
