Wherein the evaporator is installed inside the nutrient tank and has a bottom opening for the flow of water, and in the upper part of the opening for the steam, the heating device 6 structurally combined with a steam generator made of increased heat capacity of the material and has within channels 7 for the flow of coolant, wherein upper channel 7 is connected to the upper portion of the steam generator and the lower channel is connected to a nutrient tank.
DESCRIPTION OF THE INVENTION
The invention relates to domestic heating systems and can be used for heating individual houses, garages, etc.
Preferential use- heating of country houses and small greenhouses.
There are a variety of boiler installations, including using an electrode boiler. For example, a known electrode boiler plant contains the nutrient tank, the pump, the electrode boiler and control unit. Another well-known boiler system contains nutrient tank, equipped with level control, a sealed electrode boiler, expansion tank, and feed conduit of steam-pipe with shut-off valve.
Known steam, based on the work which laid the action of the electrode boiler principle.
The closest in its technical solution is a system of steam heating of low pressure to the upper steam distribution, taken as a prototype, which contains a boiler to produce steam (steam generator) connected through a main steam pipe from the upper part of the heating device and the condensate, connected between the lower part of the heating appliances and boiler.
The disadvantages are the complexity of the system in the service of steam boilers, high temperature surface heating appliances, difficulty controlling the temperature of heated space, large heat losses in pipelines.
The technical result is achieved by the invention is to simplify the design while improving the efficiency of the boiler plant autonomous steam heating.
This is achieved in that the independent heating a steam heating comprising nourishing water tank provided with a level regulator, a steam generator connected to a nutrient tank and the heating device connected between a steam generator and a nutrient tank, the steam generator is configured you a tubular evaporator equipped with an internal side electrode included in the electric network and installed in a nutrient tank, wherein the evaporator has a bottom opening for the flow of water, and in the upper part of the opening for the steam and heating unit structurally combined with a steam generator made of increased heat capacity of the material and has a within the coolant flow channels, the upper channel connected with the top of the steam generator and the lower channel nutrient tank.
The invention consists in the fact that the heating and evaporation of water is performed in a tubular container of small volume by evaporation of electric current between the electrodes through the evaporator total volume of water enclosed in the evaporator, which increases the rate of vaporization.
Changes in water level in the nutrient tank leads to a change of volume of water evaporated in the evaporator, which changes the evaporation rate and as a result, can adjust the heating temperature of the heater walls.
Implementation of the heating device of high specific heat of the material allows to take advantage of the regenerative heat exchanger: high-temperature coolant (steam), moving at high speed through the channels of the heating unit heats the structure, which heats the room as a convective method, and radiation not only during, but also after switching off boiler installation.
Combining the unitary structure in the boiler plant and heater prevents heat losses in the pipes, which increases the efficiency of the steam heating system.
Distinctive features of the invention are the introduction of a tubular evaporator provided with electrodes on the inside and installed inside the nutrient tank; structurally combined with the introduction of the steam generator heater made of a material of increased heat capacity and having inside the coolant flow channels.
These features are known from the literature, but in relation to the prototype they are new and allow to show new properties, namely to simplify the design while improving the efficiency of the boiler plant autonomous steam heating.
The drawing schematically shows the construction of the boiler plant battery.

Autonomous boiler plant steam heating is a nutrient tank 1 which is filled with water to a height of 2, determined by the level regulator 5. Inside the tank 1 is mounted nutrient tubular vaporizer 3 which is made of an insulating material such as ceramics in form of a round tube, rectangular or any other cross section. From inside the evaporator tube has electrodes 3, 4 which are included in the electrical network. 3 has a tubular evaporator at the bottom of the hole 2 for receiving water from the nutrient tank 1 and the top of the steam outlet opening. The heating device 6 is performed from the increased heat capacity material such as ceramic, and has inside channels 7 for the flow of coolant. The heating device 6 is mounted on the tubular vaporizer 3 so that the upper opening of the evaporator 3 is connected with the upper heater duct 6. This outlet channel bottom heater 6 is connected with the upper part of the nutrient tank 1. Channels 7 heater 6 to form a closed path of movement coolant: opening for the vapor to escape from the tubular evaporator 3 upper channel intermediate channels lower channel water heater 6 2 nutrient tank 1 lower opening for the inflow of water into the evaporator 2 3. |
Independent boiler installation operates as follows
Turn level 5 set the desired water level 2 in the nutrient tank 1 defined by the required room temperature heating. Nutrient tank 1 is filled with water 2 to a specified level. Due to the properties of water 2 communicating vessels fill the tubular evaporator 3 to the level set by the regulator 5.
When the electrodes 4 through the electricity network in the entire volume of water contained between the electrodes 4 inside the tubular vaporizer 3, an electric current flows, whereby the water is heated and boils to form steam. vaporization rate is determined by the magnitude of the ionic conductivity of the water and the active area of the electrodes.
The steam from the upper opening of the tubular evaporator 3 is supplied to the channels 7 a heater 6, which condenses, giving the walls of the device 6 heat of vaporization. The resulting condensate flows from the lower channel heater 6 in a nutrient tank 1.
The process of evaporation and leakage of coolant through the channels of the heating device is continuously while electrodes 4 are included in the electrical network and the nutrient tank 1 is filled with water 2.
The heating device 6 gives heat to the surroundings as a convective method, and radiation, wherein the radiation is almost two times higher than the radiators 4, which increases the efficiency of the heating system.
Level controller 5 allows to change the water level 2 in a nutrient tank 1, and hence the amount of water evaporated in the evaporator tube 3. The latter circumstance leads to a change in evaporation rate and ultimately to an increase or decrease in temperature of the heated space.
Offered steam heating system is completely autonomous. It requires virtually no maintenance. In the case of complete evaporation or leakage of water from the nutrient tank electrical circuit is open, the machine will automatically turn off from work. Filling nutrient water tank is made at the beginning of operation. In the future, you only need to compensate for water loss due to unforeseen leaks of steam.
Installation is safe, because the coolant is low-temperature steam and the temperature of the heating unit of the walls does not exceed 100 ° C.
