Description

Universal fireplace insert.

Universal fireplace insert refers to devices for heating and can be widely used in the construction of industrial, office and residential premises to create comfortable conditions in them.

There are various designs of fireplaces, the prototype of which is a classic English fireplace, but the main disadvantage of such fireplaces with an open firebox, usually laid out of refractory bricks, is the low efficiency of the fuel system, which does not exceed 10-15%. Currently, the design of fireplaces widely use systems of metal (cast iron and steel) fireplace inserts, the efficiency of which reaches 85-90%

Known Fireplace, containing under the firebox, firebox, rear wall with pinch, chimney, ash chamber with grate and door, moreover, it is equipped with an air supply distribution system installed in the firebox, connected to the atmosphere through a wind-extinguishing device with a main air duct with two air ducts branched from it with regulating flashlights installed in them, while one of the ducts is in communication with the ash pan chamber, and the other with an air supply distribution system, area main duct cross-section is not less flue-sectional area in the narrow part thereof, and the ratio of cross sectional areas of the duct is equal to 3: 1.

- Patent of the Russian Federation No. 2045711; 6MKI: F24 V 1/18, Pub. 10/10/95, bull. Number 28.

Known Fireplace for creating comfort in the room, containing a firebox and a chimney with a device for blocking it, while in the chimney a side supply pipe is made with its own device for blocking it, with the input end of the pipe located outside the room and the output above the device for chimney overlap.

RF patent No. 2130567; 6 MKI: F 24V 1/185; pub. May 20, 1999, bull. Number 14.

Known Fireplace and a device for simulating burning logs, containing the outer walls and the firebox mounted inside them, and the inner space between the walls and the firebox is filled with loose mineral material, and the firebox is made of stainless steel sheet.

Certificate of the Russian Federation for utility model No. 12602; 7 MKI: F24B 1/18, Pub. 01/20/00 g., Bull. Number 2.

Foreign companies have also developed and are implementing a large number of different designs of metal fireplace inserts, differing from each other in size depending on the required furnace power and heating efficiency.

Closest to the proposed technical solution is Koshtakova’s fireplace, containing a firebox with a fuel opening limited by the hearth, arch, side and rear walls of the fireplace, a chimney limited by the front, side and internal walls of the fireplace, and a chimney, the arch being made with its front edge made horizontally , is located above the upper edge of the fuel opening, obliquely from the rear wall down forward to

the fuel opening along its entire width, forming a protrusion with the inner wall, and with the front wall - the exit of the chimney into the fuel space. Certificate on the floor. model No. 0001730 to the patent of the Russian Federation; MKI: 24V1 / 188, .02.96. The disadvantages of the above devices include low heat transfer during fuel combustion.

The technical result of the proposed technical solution is to increase the heat transfer during fuel combustion by using a smoke collector with a heat accumulator, which contributes to the accumulation of thermal energy and its slow release, reducing the time of building a fireplace using block chamotte stoves, as well as the versatility of the fireplace using a kitchen unit docked with a fuel opening.

The technical result is achieved due to the fact that the universal fireplace insert containing a fuel chamber with a fuel opening limited by a hearth, side, rear and front walls with internal protrusions, a smoke collector which is made horizontally with the lower front edge and is located above the upper edge of the fuel opening, and moreover, the chimney of the fireplace insert is made of chamotte blocks, and the smoke collector is equipped with a heat accumulator made of a set of pieces of heat-absorbing material placed on a slot arch of 3-4 horiz ontal lintels made of stoves, the ends of which rest on the upper internal protrusions of the plates of the front and rear walls of the fireplace insert. The fuel chamber is equipped with two or three fuel openings with which the kitchen unit is fitted, equipped with a cast-iron stove with a door and a blower.

In FIG. 1 - a general view of the fireplace insert in front and side;

in FIG. 2 - sections of the fireplace insert along A-A and B-B

FIG. 3 - options for a fireplace with two and three fuel openings

FIG. 4 is an embodiment of a fireplace insert with a docked kitchen unit.

.According to figures 1, 2, a universal firebox contains a fuel chamber with a fuel opening limited by a hearth, side and rear walls, and a smoke collector made like firebox walls from fireclay plates. The chimney is equipped with a heat accumulator made of a set of pieces of heat-intensive material placed on a slot arch of 3-4 horizontal jumpers. The jumpers are also made of fireclay plates, the ends of which are based on the inner protrusions of the front and rear walls of the fireplace insert. The product finishes with a chimney.

All parts of the proposed device are made of industrial refractory products (fireclay plates) according to GOST 390-96, which have high heat capacity, which is important for the process of long-term heat transfer of this device. The chimney is made of brick, asbestos cement or metal pipe.

The main part of the device - the internal heat accumulator is made of a set of chamotte scraps - waste products from stoves, fireplaces, ceramic solid or chamotte bricks, stones of various rocks (granite, gabbro) and other heat-intensive materials.

The structure of the internal heat accumulator breaks the smoke stream into many thin jets flowing around individual plates (stones) from all sides

and effectively heat them and the heat accumulator as a whole, as a result of which this device can be considered more “faster than conventional furnaces.

Fig. 3 shows two other versions of the fireplace insert with two and three fuel openings used in modern fireplaces. The option with two openings is usually used in corner fireplaces, the option with three openings is more rare. As can be seen from the figure, the design of such devices in this case is very simple.

In FIG. 4 shows an embodiment of a fireplace insert with a docked kitchen unit containing a cast iron stove with a door and a blower.

The proposed fireplace insert combines the advantages of both stoves and fireplaces, has versatility in connection with the ability to use it with one, two and three fuel openings, as well as a kitchen unit docked with the fuel opening.

A universal fireplace insert provides an increase in heat transfer during fuel combustion through the use of a heat accumulator located in the smoke chamber space and the use of heat-resistant refractory material in the design.

In addition, significantly reduces the time of manufacture of the fireplace insert through the use of stove-block construction.
