Description

FIELD OF TECHNOLOGY

The invention relates to sanitary-hygienic facilities, in particular to sauna furnaces, and can be used in individual, rural saunas, urban-type saunas and saunas, and also for heating rooms.

BACKGROUND

Known ovens of the closed type, for example in a metal case. In height, such a furnace is divided into three zones: the lower one serves as a firebox, the middle one as a heater, and the upper one is used for heating water. The casing of the furnace in the furnace and heater zones is laid out inside with red brick on the rib. Stones are placed on the sections of the rails over the firebox. Water is supplied to the heater through a side hole in the casing, designed to remove steam, closed by doors. A container with a lid is placed above the heater, the water in which is heated by the flue gases leaving the chimney. The advantages of this arrangement of the tank for heating water is that a large amount of heat is given to the stones and the water does not boil, thereby maintaining a low relative humidity of the bath’s air, (see I. Shulgin. You are building a bathhouse, Kiev, Urozhay, 1993, p. 82). However, the heat capacity of such a furnace is low and it cannot be used for large rooms.

Known metal furnaces, such as a stove-heater designed by Mikhailov (see I. Shulgin. You are building a bath, Kiev, "Harvest", 1993, p. 88). The furnace is welded from steel sheets with a thickness of 35 mm. It has two chimneys: the main one is for the furnace, the additional one for the release of smoke and carbon monoxide, when the bath is already heated, and the firewood has not yet burned out. The furnace consists of a furnace with a blower, a heater and a pipe. The kit includes two valves, large and small, a heater grill and a blower grille. A hot water tank is mounted on the front ledge of the furnace above the firebox. During furnace heating, the water in the tank heats up almost to a boil. When the furnace is heated, only the large valve in the flange on the pipe is left open, the small valve is closed. When the firewood is almost burned out, you can open a small valve, and close a large one. Residual smoke and carbon monoxide will pass through the second channel, bypassing the heater. Opening the door of the stove and splashing 1-2 cups of hot water on the stones, get dry hot steam. The furnace is installed no closer than 25 cm from the wall. To reduce the heating of the wall, the inner surface of the furnace, facing the wall, is laid with a brick on the edge. This does not allow the stove to glow red from this side. This design of the furnace has the following disadvantages:

Along the wall with a gap of 5 cm, a flat asbestos-cement sheet or steel sheet is installed to the height of the furnace. Asbestos cement is harmful to health;

- At an air temperature above 80 ° C, a burn of the nasopharynx and bronchi is possible, and at 150 ° C, hard infrared radiation is produced that is harmful to health, and organic components and oxygen burn out in the air.

When installing any metal furnace, it is necessary to carry out the following fire-fighting measures: the external surfaces of the furnace, pipes, smoke channels, which are close to combustible structures, are insulated with heat-insulating non-combustible materials, such as brick (which significantly increases the cost of the structure), or asbestos, which is harmful to health.

A well-known universal metal furnace containing a furnace with a blower over which a closed-type heater and a chimney are located, characterized in that the walls of the universal furnace are double with the possibility of filling the space between them with water or another heat carrier, while the outer walls of the universal furnace are equipped with devices for inlet and outlet of the coolant, and the heater in the upper part is equipped with holes for supplying water and removing water vapor. (UA No. 92441, publ. 10/25/2010, Bull. No. 20).

The well-known sauna stove is selected as a prototype. The prototype and the claimed utility model have the following common features:

- Firebox;

- chimney;

- Kamenka;

- Double walls of the furnace with the ability to fill the space between the walls with water or another coolant;

- The outer walls of the furnace are equipped with devices for supplying and removing coolant.

However, this prototype has several disadvantages, in particular the need to use a high chimney, which significantly reduces the possibility of using the furnace. Also, the separate location of the heater does not allow the efficient use of the energy of burning fuel.

ESSENCE OF A USEFUL MODEL

The basis of the invention is the task of creating a more economical to operate and more efficient furnace, which can be used both for bath procedures and for heating.

The problem is solved by the fact that the declared bath-heating furnace containing a housing, a chimney and a furnace, above which is placed a container with heat-accumulating material (heater), the chimney is immersed in the furnace, and the heater is located around the chimney.

The furnace body is a water-steam system with double walls, one of which forms a furnace, and the other - the furnace body, and the space between them is filled with water and steam.

The water-steam system is equipped with devices for supplying and removing water and a device for removing the resulting steam.

What is new in the claimed utility model is that the chimney of the furnace is immersed inside the furnace of the furnace and is lined around with heat-accumulating material (heater) and together form a single system that allows you to create a "fuel hood".

Such a cap contributes to the combustion of pyrolysis gases generated during the combustion of fuel, increases the efficiency of the furnace and allows you to select almost all of their thermal energy from flue gases (fuel combustion products) and direct it to heating water and steam. At the same time, the heater is located in the hottest place of the furnace - around the chimney, which allows it to heat up to high temperatures in a short time without the need to add new fuel material.

This design significantly increases the efficiency of thermal energy during fuel combustion. The use of a fuel cap in the furnace design allows to obtain efficiency during fuel combustion, which cannot be achieved for once-through furnaces.

The design of the chimney, namely its location inside the furnace, makes it possible to use the chimney not only as a device for exhausting smoke, but also as a pump for already cooling flue gases and pushing them out, that is, a draft for smoke is created inside the furnace and it does not need a long chimney , which is the rest of the stoves, which allows the use of budget options for chimneys.

Additionally, the furnace may contain a safety gravity valve in the steam-water system to prevent critical pressure increase of the coolant in the system and damage to the furnace.

In addition, a reservoir can be used as a coolant supply system, the coolant level in which is at the same level as the coolant in the furnace, where the coolant level in the water-steam system is maintained by the tank according to the principle of communicating vessels, and the coolant level in the tank itself is maintained by the system that controls the level of water, such as float.

As a superheater in the furnace, heat-accumulating material located around the chimney and connected to the water-steam system by a channel can be used.

Additionally, a flexible heat-insulated hose is used as a device for removing steam.

DETAILED DESCRIPTION OF A USEFUL MODEL AND ITS IMPLEMENTATION

The bath-heating furnace is made in the form of a metal tank with double walls, which are made with the possibility of filling the space between the walls with water or another coolant. The outer wall of the furnace is equipped with devices for supplying and removing coolant. Above the furnace there is a heat storage material (heater) and a chimney.

The furnace includes an opening for filling fuel into the furnace 1, the furnace 2 itself, above which the heater 3 is placed. The furnace heater is formed by a metal tank immersed inside the furnace, one of the walls of which is a chimney 4, as well as the upper wall of the furnace.

The heater can be divided into two parts: a high-temperature “lower” heater 3 and a low-temperature “upper” heater KA, located on top of the furnace. The upper stones are heated from the upper wall of the furnace to a relatively low temperature, so they practically do not create convection currents and do not overheat the bath.

The top layer of the heater is perfect for evaporating aromatic tinctures, and also acts as a “cover” for the lower, high-temperature layer of the heater.

The high-temperature “lower” heater is located in the hottest place of the furnace, which causes heating to 400-600 ° C (depends on the properties of the heat-accumulating material of the heater).

The furnace body is made with double walls: inner 5 and outer 6 with the possibility of filling the space 7 between the walls with water or another coolant. The inner wall forms the furnace of the furnace 2.

The outer wall 6 is equipped with devices for supplying and discharging water 8 and devices for removing steam 10.

In the upper part of the furnace there is a safety gravity valve 11 to prevent a critical increase in the pressure of the coolant in the water-steam system and as a result of damage to the furnace.

The furnace is equipped with a chimney 4, which is immersed in the furnace 2 and laid around a heat-accumulating material (heater) and forms a single system that creates a “fuel cap” 12.

The utility model works as follows. Fuel is placed in the furnace 2 through the hole 1 and ignited.

Due to the effect of convection and radiation heat from the fuel, the pyrolysis gases generated during the combustion of firewood in the furnace 1 heat the heat-accumulating material (heater) 3, the chimney 4, the inner wall of the furnace 5 and the water located in the space 7 between the double walls of the furnace (5 and 6), which when heated above 100 ° C turns into steam.

As a result, due to the pressure difference in the water-steam system and the atmospheric air in the steam room, the received steam with a temperature of 110-140 ° C enters the steam room through the steam exhaust devices 10, however, the final temperature depends on the water level in the furnace and the thermal power of the fuel in the oven.

As the superheater in the furnace, heat-accumulating material (heater) connected to the water-steam system by channel 9 can be used.

Various devices for using steam can be connected to the steam exhaust devices. For example, such a device may be a flexible insulated hose 13 as a steam shower.

Water is supplied to the water-steam system through the device 8 from a third-party tank and is maintained in the water-steam system at an appropriate level with the water in the tank according to the principle of communicating vessels, and the water level in the tank itself is due to a system that controls the water level 14, for example, float-operated .

The water-steam system also performs thermostabilizing function for the furnace, as a result of which the material of the furnace walls does not overheat, which significantly increases the life of the furnace. In turn, the temperature of the outer wall of the furnace does not heat up to temperatures above 140 ° C. Thus, the furnace cannot overheat the steam room and is a source of low-temperature (“soft”) thermal radiation, contributes to a uniform and deep heating of the human body without the harmful effects accompanying other furnaces, in particular without uncontrolled convection and air overheating in the steam room.

Further, the flue gases, cooling off, due to the draft created by the chimney, are drawn into it and sent outside the premises.

When the furnace ceases to be heated, the water located in the space 7 between the walls 5 and 6, cooling down, dries the bath room.

The stove can also be used for heating any room and for producing hot water. To do this, through devices 8 for supplying and discharging the coolant, any closed heating system 15 is connected or water is taken.

The bath-heating stove is convenient to manufacture, economical in operation and, when used, creates comfortable conditions for visitors to the bathhouse.

The presence of a hood and an internal chimney makes the bath-heating furnace insensitive to the type and height of the external chimney. An external chimney can be of any length and is intended only for the removal of flue gases outside the room. Due to the increased use of thermal energy obtained from fuel combustion, the temperature of the flue gases in the furnace is low, which also determines the fire safety of the furnace.
