The invention relates to the design of the furnaces and how to generate superheated steam and can be used at the equipment of baths stationary and mobile types, as well as for heating of living and production premises.

Known stoves for baths containing metal case, the furnace, the camera in her stones and chimney installed on the camera. When operating get pure steam, splashing on the rocks hot water (Patent RU №2005263 C1, IPC: F24 1/24, 07.03.1993).

The disadvantage of these stoves is the possibility of falling into the sauna room of the flue gases and the presence paired with relative humidity up to 70% of large drops brought to the boiling water. While it is impossible to obtain superheated steam with relative humidity less than 25%.

Known methods for producing superheated steam of wet steam of high pressure through separation of liquid from steam throttling and overheating due to heat exchange with saturated steam and thereby increasing efficiency (A.S. USSR 561048 And, IPC F22G 1/10, 01.08.1977).

The disadvantage is the need for additional steam generator and the difficulty of stabilization of temperature of superheated steam.

Known furnace for bath containing metal case with the furnace chimney and open container with heat coarse material, with the specified public container is placed in the upper part of the furnace from the heated premises, placed in the furnace capacity of high pressure heat exchanging coarse material and installed in the upper part viagraprednisone device connected to the tank for evaporative fluid through the dispenser in the specified capacity built from the bottom up throttle pipe passing through the heat exchanger coarse material and the upper part of the furnace in the specified open container, providing additional overheating formed in the vessel, high pressure superheated steam in the upper part of the furnace and for the account of recuperative heat exchange with coarse material (RF Patent №2250417, IPC: F24B 1/00, 5/00).

Specified furnace operates in the following way.

In the furnace metal housing through the door lay the fuel and ignited. The remains of combustible fuel Wake up through the grate in the ash-pit. Hot gas resulting from combustion of fuel goes up the furnace, a heat exchanger heats coarse material in tanks and containers, as well as pairs in the upper part of the throttle pipes. Then the hot gas, rising up through the chimney, heats a water tank. Gradually heat coarse material is heated to 350-450 C, heating the air in the room up to 60-100°N

The way of overheated steam, implemented using the specified furnace, is the following.

To obtain superheated steam evaporative fluid from the tank through the throttling channel with pipe comes in viagraprednisone device. Liquid is heated during its contact with the heat exchange coarse material. Formed saturated steam rises into the upper part of the vessel and then, with the increase of its volume, under its own pressure seeps through coarse material, more heated over 100 C and fed into the inlet choke tubes at the bottom of the tank. Next, superheated steam is heated to the horizontal section of the throttle body pipe in the upper part of the furnace. Drosslerova steam enters into an open container and in the process of recuperative heat exchange with coarse material is overheating more than 110 OC, through the heating of the room.

The disadvantage of this oven is the need for additional viagraprednisone device and the difficulty of stabilization of temperature of superheated steam.

The objective of the invention is to eliminate these disadvantages and create a device for generating steam for stoves, the construction of which will allow to increase the heat output of products of combustion of fuel and significantly increase the time of the furnace at a constant fuel with superheated steam with controlled temperature and humidity.

Fulfillment of this task is achieved by the fact that the proposed device for generating steam installed, mainly, in the furnace for bath-houses, according to the invention, contains a capacity for evaporative fluid with inlet and outlet branch pipes, with the top and bottom of the base and side wall, and made mainly in the form of a hollow cylinder, with the output part of the input pipe to supply evaporative fluid inside the listed capacity is placed in the lower part of the mentioned capacity, preferably, on the lower ground and the input part of the input pipe is located above the upper Foundation, and the input of the output socket is located on the top Foundation, and the outlet is made in the form of a spiral, mainly, the spiral of Archimedes, the diameter of coils specified spirals made in such a way that provides installation mentioned spiral on the heating element of the furnace, mainly, the chimney furnaces.

The invention is illustrated by drawings, where figure 1 shows a longitudinal section of the unit mounted on the furnace, figure 2 - the device is a perspective view.

The proposed device for generating steam contains a tank 1 for evaporative fluid with inlet 2 and outlet 3 pipes, respectively. Capacity 1 includes the top 4 and 5 lower base, respectively, and the side wall 6, made in the form of a hollow cylinder 7. The output part 8 input socket 2 for filing evaporative fluid inside the listed capacity 1 is located on the under 5. Input 9 input socket 2 is located above the upper base 4. Entrance part 10 of the outlet pipe 3 is located on the top 4 basis. Output tube 3 is made in the form of a spiral, mainly, the spiral of Archimedes, the diameter of coils specified spirals made in such a way that ensures the installation mentioned spiral on the heating element of the furnace, mainly, the chimney 11 furnace 12.

The proposed device for generating steam works as follows.

A device for generating steam is placed on the stove 12 thus, to ensure contact of vessel walls, 1 and the outlet of 3 with heating elements furnace.

For steam oven is heated by burning of fuel in it, mainly firewood.

Inside the tank 1 for evaporative fluid, including the top 4 and 5 lower base, respectively, and the side wall 6, made in the form of a hollow cylinder 7, through the inlet 2 is filled evaporative fluid is mainly water. Due to the fact that the input 9 input socket 2 is located above the upper base of the 4-capacity 1, and output 8 - on the under 5, liquid level in the tank 1 will always be below the liquid level in the input socket 2, or, at least, at his level.

During the evaporation of the liquid inside the tank 1 due to its warm during operation of the furnace 12 the lowering of the level of liquid in the tank 1, but, on the principle of communicating vessels, in the capacity of 1 will receive the liquid from the input socket 2 up until the liquid level in the tank 1, and in the input socket 2 not reach the same value. This design eliminates the emission of hot steam through the inlet 2 at any level evaporative fluid in the tank 1 and you continuously add evaporative fluid in the capacity of 1 as it evaporation, depending on the mode of operation of the furnace and the temperature in the bath room.

Formed pairs from the reservoir 1 through the inlet part 10 of the outlet pipe 3 goes up to the output side of the pipe 3. Due to the fact that the outlet is made in the form of a spiral, installed on the chimney 11 furnace 12, there is a further warming and drainage pair. Temperature and humidity get a pair regulated by changing the mode of operation of the furnace and degree of filling the evaporative fluid capacity 1. From the output pipe 3 steam enters the bath room.

Conducted by the author, applicant tests of the full-size sample of the furnace with the proposed device for generating steam confirmed the correctness laid technological design solutions.

The use of the proposed technical solutions allows to create a device for generating steam, the construction of which will give an opportunity to increase the heat output of products of combustion of fuel and significantly increase the time of the furnace at a constant fuel with superheated steam with controlled temperature and humidity.
