(EN) The invention relates to power engineering. The aim of the invention is to increase the efficiency of an engine powered by low-potential heat. The engine is installed outside the heat source. It is a sealed vessel of heat-conducting material formed by two concentric walls, between which is a partition dividing the vessel into the inner and outer regions, and filled with a liquid working medium, for example water with an air cushion. The engine has a turbine, an electric generator, designed in such a way that the stator is fixed to the partition at the level of the turbine, and the windings of the rotor are placed in the turbine. As a means of cooling used atmospheric air, which simplifies the design of the engine and does not require energy to cool the working fluid.
DESCRIPTION OF THE INVENTION
The invention relates to thermal machines, and more particularly to thermal motors powered by low-potential heat.
A gravitational-thermal engine is placed inside the chimney, made in the form of a cylindrical vessel filled with water with an air cushion, with a cylindrical partition that does not reach the top and bottom of the vessel. The septum divides the vessel into the inner and outer regions. In the upper part of the vessel is fixed a turbine, kinematically connected to an electric generator, above which is placed a refrigerator [1].
The disadvantage of the known engine is its low performance.
The aim of the invention is to increase the efficiency of the engine.
This object is achieved in that the engine, which is a sealed vessel of heat-conducting material, filled with an air-cushioned liquid working fluid and having a cooling means, a turbine and an electric generator, has the form of a container formed by two concentric cylindrical surfaces and separated by a cylindrical partition not reaching the top And the bottom of the vessel and dividing the volume of the vessel into the inner and outer regions. The engine is placed from the outside of the source of low-potential heat.
In addition, the generator is designed in such a way that its stator is fixed to the partition at the level of the turbine, and the windings of the rotor are placed in the turbine.
In addition, atmospheric air is used as the cooling medium.
The essence of the invention is explained in the drawing, which shows the vertical section of the engine.
The device of the proposed gravitational-thermal engine will be considered with reference to the case of use as a source of low-potential heat of the chimney.

The proposed engine is a sealed vessel of a heat conducting material formed by two concentric cylindrical walls: an inner 1 and an outer 2, inside which is placed a cylindrical partition 3 dividing the volume of the vessel into the inner 4 and outer 5 regions. The turbine 7 is installed in the upper part of the vessel on the bearing 6. The stator 8 of the power generator is fixed to the partition 3 at the level of the turbine 7, and the rotor windings are placed in the turbine 7. Below the turbine 7 are fixed the annular guides 9 and 10 forming the narrowing of the region 4. The motor is mounted on the wall 11 of the chimney so that the inner wall 1 fits snugly against the windows 12 in the chimney wall 11. The internal volume of the engine is filled with a liquid working fluid, for example water, so that an air cushion remains at the top of the engine's volume. The engine works as follows. Flue gases passing through the chimney at a temperature of 150-350 ° C through the windows 12 and the inner wall 1 heat the water in region 4. The water boils. The resulting steam-water mixture has a density less than the density of water and rushes upward. Climbing in area 4, the steam-water mixture accelerates and in the narrowed part between the guides 9 and 10, acting like a nozzle, reaches the maximum speed and drives the turbine. The rotor windings located in the turbine 7 cross the magnetic power lines of the stator 8, resulting in an electric current. Working in the turbine 7, the steam-water mixture cools, the steam condenses. After that, water passes into region 5, descending along which it is cooled by atmospheric air through wall 2. In the lower part of region 5, water flows into region 4. The process is repeated. |
Cooling water with atmospheric air simplifies the design of the engine and does not require energy for cooling the water. Thus, the efficiency of the proposed engine is increased.
