| The invention relates a method and to a device (1) for converting thermal energy of a low temperature heat source (20) into mechanical energy in a closed circuit. The method consists of heating a liquid working agent by transmitting heat from the low temperature source (20) and partially evaporating it in an expansion device (3). According to the invention, erosion to the condenser (8) for condensing the partially evaporated working agent can be prevented by separating the liquid phase from the evaporator phase in the partially evaporated working agent that is directly in front of the condenser (8), and only the evaporator phase is transferred to the condenser (8) for condensing and subsequently, the condensed evaporator phase and the liquid phase are merged. | ||||||

When it is combined with the first working medium (6) that is enriched with thermal energy, it changes to a gaseous state or expands and produces an excess pressure and performs work in such a manner that a torque is applied to the rotating element (3; 3.1-3.6) of the heat engine (1). | ||||||

| Power is generated from heat from a source such as geothermal brine or the cooling system and exhaust of an internal combustion engine. The heat is used to boil a non-aqueous working fluid by heat exchange in a boiler. Wet vapour from the boiler is fed by a line (22) to a positive displacement twin-screw expander (23). The expanded fluid is fed by a line (15) to a condenser (17) from which it is returned by a feed pump F to the boiler. The flow rate through the boiler and expander is controlled by a controller (33) responsive to pressure and temperature sensors monitoring a tapped-off throttled sample flow through a chamber (30) to control the dryness of the fluid in the line (22). Lubricant for the expander may be included in the liquid phase. | ||||||

| 214 | OSMOTIC UNIT FOR A STEAM ENGINE | PCT/UA2016000149 | 2016-12-20 | WO2017111765A8 | 2017-08-24 | RASSOKHA IGOR NIKOLAEVICH |
| An osmotically imbalanced vapour-osmotic unit for a steam engine comprises a vessel which is divided by a selective membrane (4) into compartments (A) and (B) such that the compartments contain a solution of a common fluid, for example water, and a substance (a) and (b) respectively. A circulating loop of the vessel contains a working assembly (6), for example a steam turbine. The selective membrane (4) is pervious to the common fluid, but is completely impervious to substances (a) and (b) respectively. The boiling point of the solution containing substance (a) is lower than the boiling point of the solution containing substance (b). Under operating conditions, when the boiling point of the solution of a common liquid and substance (a) is reached, the common liquid begins to circulate as follows: "compartment (A) – steam – working assembly – steam (condensation may already take place in the working assembly) – compartment (B) – selective membrane (4) – compartment (A)", wherein the solutions in compartments (A) and (B) are osmotically imbalanced, as a result of which the osmotic pressure of the working fluid is constantly directed from the solution in compartment (B) to the solution in compartment (A). The vapour-osmotic unit enables the circulation of the common fluid without the use of a pump. | ||||||

| The invention relates to a device for converting heat energy into mechanical energy. A first fluid takes a first path between a first inlet and outlet of a steam generator (201). The heat-transfer fluid takes a second path between a second inlet and outlet of the steam generator. The first path is thermally coupled to the second path so as to form the steam from the first fluid. The first fluid, in the form of steam, takes a first path between a first inlet and outlet of an expansion chamber (202). The heat-transfer fluid takes a second path between a second inlet and outlet of the chamber. The chamber is formed so as to carry out the isothermal expansion of the first fluid using a fractionated expansion via a plurality of basic isothermal expansions, the first fluid being heated between each expansion. The first fluid is mixed, in the form of steam, with the heat-transfer fluid so as to obtain a dual-phase mixture in a mixing device (204). | ||||||

The system comprises a heat source providing exhaust gas. The exhaust gas provides thermal energy for evaporating the fluid from liquid phase to gaseous phase by the evaporator. The system further comprises a generator unit for converting mechanical energy from expander to electrical energy. The expander is a volumetric expander. | ||||||

| An electricity generator comprises a field vessel (1) that is held at a pressure below atmospheric pressure. A hot end of the vessel (1) is heated by hot waste water (4) generated by a power station. A heat transfer medium, such as water (3) is thus heated and evaporates. The upwardly moving heat transfer medium is directed through an opening (5) onto the blades of a turbine (9). The turbine (9) is caused to rotate, and magnets on the blades of the turbine (9) cut lines of flux provided by a coil (11) located on the exterior of the vessel (1). An electric current is thus induced in the coil (11) and then is subsequently collected by a power electronics module (12). | ||||||
