Description

The invention relates to furnace heating systems - to furnaces that provide both heating and vaporization, is used in individual baths.

Wood bath stoves are known in the art.

So, for example, a heating furnace is known, containing a firebox, an ash pan, a flue, which are equipped with doors, as well as a chimney and a heat storage charge. In this case, the furnace is made in the form of a vertical metal structure, closed externally with a brick casing, the gas duct contains several hoods sequentially mounted on supports and connected to each other and with the furnace by exhaust pipes, while the furnace and caps are made in the form of horizontally arranged metal pipes, in the upper part the air supply pipe is mounted on the lower hood, the inner surface of the firebox is half lined with fireclay bricks, a heat-accumulating load in the form of a stone is laid between the firebox and the hoods, convection holes are made in the lower and upper parts of the brick casing (RU 177316 U1 02.15.2018).

In addition, a bath furnace with a separate steam room, a sink and a dressing room is known, containing a single-walled rectangular metal housing in which a firebox with a loading door is located, with a grate and an ash pan, a heater is installed above the firebox, including a container with heat-accumulating elements, the furnace cavity is connected through an air duct system with a chimney, a container for heating the washing water is installed on the side of the furnace, a furnace with heat-accumulating elements is arranged to be placed in the steam room of the bath, and a container for heating the washing water adjacent to the furnace is installed in the washing compartment of the bath. Moreover, the furnace further comprises seats for removable frontal and longitudinal heat accumulators for heating the steam room, washing and changing rooms, a seat for longitudinal heat accumulators for heating the steam room and washing rooms contains a rectangular metal plate mounted on the upper side of the furnace body along its length, a seat for the front the heat accumulator for heating the dressing room is made in the form of a rectangular pipe - a loading tunnel installed between the loading door and the entrance to the furnace, while a rectangular metal plate for landing the heat accumulator for heating the steam room and the sink is made with a thickness of 3 to 5 mm, lengths from 300 to 700 mm and a width of 80 to 200 mm, and the loading tunnel is 100 to 400 mm long and with transverse dimensions of 300 to 600 mm, 300 to 500 mm in height and width, respectively.

The disadvantages of previously known stoves in heating the stone for too long or the impossibility of heating the stone to temperatures of 400-600 degrees, have high infrared radiation (IR), a large number of firewood is needed, have low durability, have large dimensions, low ergonomics and high fire hazard. The objective of this furnace is to create a convenient and safe furnace for heating a large amount (from 120 to 800 kg) of stone to a temperature of 400-600 degrees Celsius in a short period of time (2-3 hours) and providing comfortable soaring without IR radiation, as well as creating baths "in the black."

The technical result consists in reducing the duration of heating a large amount of stone to 400-600 degrees, creating a temperature in the steam room from room to 120 degrees and humidity from 5 to 100 percent, reducing IR radiation, reducing firewood consumption (high efficiency), high durability, reducing dimensions, increased ergonomics, low fire hazard, the absence of the likelihood of carbon monoxide poisoning, low furnace weight - a reduced load on the foundation.

The indicated technical result is realized due to the following design features: The furnace body has a cylindrical shape, thermal insulation (1) mineral wool or foamed is placed on the inside of the case to maintain heat in the heater and create an obstacle for the exit of infrared radiation (IR) to the outside. In the lower part of the housing, lockable holes (2) are located around the perimeter, which make it possible to regulate the intensity of air supply to the air preparation chamber. The firebox (3) is located inside the housing. The furnace is fixed on the platform with legs adjustable in height, on which the external body of the furnace also stands. The furnace has a cylindrical shape. Part of the furnace is a portal with a door for laying firewood (4). The bottom of the furnace is made inclined so that the formed coal is poured to the central part having an opening locked by the grate (5). When the grate is moved away, the coal is poured independently into the coal receiver (6) - a container for receiving coal. In the upper part of the furnace there is a hole of such a shape that ensures twisting of the outgoing pyrolysis gas.

The air preparation chamber (7), represents the space between the furnace and the inner part of the insulated body. Holes (13) for the entry of prepared (heated) air masses into the pyrolysis gas surviving chamber have guides (14) that provide directional swirling entry into the afterburner.

The pyrolysis gas afterburning chamber (8) has a cylindrical shape. The lower part of the chamber is the upper part of the furnace. The side wall is the upper side of the air preparation chamber. The upper part of the chamber is the bottom of the heater; it has at least one opening that has guides (14), which ensures twisting of the outgoing burning pyrolysis gas. The pyrolysis gas afterburner is designed for swirling mixing of burning pyrolysis gas and heated air. It ensures the survival of gases with heating to higher temperatures when the latter enter the heater, which dramatically increases the efficiency of the furnace.

Kamenka (9) is a cylindrical-shaped chamber in which the flame passes directly through the stones, while the entry of burning gases into the chamber occurs through openings with guides that support further twisting of the flame, which allows the stones to be heated evenly. The final burning of the pyrolysis gas takes place in it. At least two openings are located in the upper part of the heater: exhaust gases are discharged into one, passes into the chimney (10), blocked by a blind valve (11) to keep heat in the heater, the other with a door (12), for laying stone and adding water to produce steam.

The carbon receiver is a rectangular drawer tightly adjacent to the lower part of the furnace, having in the upper part guides for moving the grate or drawer lid on it. There are handles at the front and back of the drawer. It is placed in a pencil case under the firebox. The carbon receiver ensures the retention of firewood and coal in the furnace by means of a grate inserted in the guides, as well as the passage of combustion air with the possibility of regulating its supply.

Upon reaching the required temperature of the stone in the heater, the grate is taken out, the coals are poured into the coal receiver, which is closed by a lid. At the same time, coal fades in an oxygen-free environment, which makes it possible to use it further. The invention is illustrated by drawing 1, where:

1 - thermal insulation; 2 - lockable holes at the bottom of the housing; 3 - firebox; 4 - a door for laying firewood; 5 - grate; 6 - coal receiver; 7 - air preparation chamber; 8 - pyrolysis gas afterburner; 9 - heater; 10 - chimney; 11 - valve; 12 - a door; 13 - holes; 14 - I direct in the holes.
