The invention relates to energy, in particular to a steam power plant, which converts thermal energy into mechanical energy. Through the use of hermetically closed working circuit this unit can run on low-boiling liquids. In this regard, the scope of the invention extends to many sectors. Steam power plant can operate to heat water geothermal sources, as well as using heat from the sun, when the heat from the cooled objects on the production of construction materials, glass, metals. The unit may be used as a standalone engine, running from the heat of combustion of many fuels. In the warm season, the plant can operate from the heat of the environment with the use of capacitor in the low-temperature zone of the body, such as dry ice. In the cold season in a hermetically sealed enclosure can be applied substances, boiling substantially below the freezing temperature of water, and water reservoirs can also be used as the heating fluid.

Known steam power installation comprising a set based supports in the steam generator and condenser are separated by a partition with a valve, condenser pump, turbine and guide device, which is enclosed in a sealed casing, rotating together with the shaft, teplopodvodyaschey and cooling devices (ed. St. N 1768768 And I, class F 01 To 11/04, 1990).

The disadvantage of this steam power plant is its low efficiency due to losses of energy expended on the work of the condenser pump.

The invention is aimed at improving the efficiency of steam power plant by reducing the operating parameters of the condenser pump.

This object is achieved in that the steam power installation comprising a set on the basis of the bearing in the managing apparatus, enclosed in a sealed casing, rotating together with the shaft, teplopodvodyaschey and the cooling device, while the steam generator is divided into sections, one of which communicates with the turbine and through the valves with the other isolated from other sections of the steam generator connected through valves to the condenser, the steam generator is equipped with a sensor operating parameters associated with the regulator supply of heating fluid. Introduction to the installation of the regulator and the separation of the steam generator section allows to reduce the operating parameters of the pump.

The drawing shows the installation diagram.

Steam power installation, comprising a base 1 with the supports 2, which rotates the shaft 3. The shaft 3 coupled to a hermetically sealed housing 4 steam installation. The inner cavity is hermetically sealed housing 4 is divided by a partition 5 into two cavities, which are placed in the steam generator 6 and the capacitor 7, and the steam generator contains isolated from each other by partitions 8 section 9, section 10 and section 11. Between the sections of the steam generator 9 and 10 in the partition 8 is the valve 12 between the sections 9 and 11 in the partition 8 is a valve 13, between the section 10 and the condenser 7 in the partition 5 is klapy section 10 from the zone for supplying the coolant to the section 10 and the separation section 10 of the cavity section 10 from the zone for supplying the coolant to the section 11. Section 11 is isolated on the periphery of the steam generator 6 insulating layer 16 from the zone for supplying the coolant to the section of the steam generator 10. Section of the steam generator 10 is isolated on the periphery of the steam generator heat-insulating layer 17 from the zone for supplying the coolant to the section of the steam generator 11. In the partition 5 in the area of section of the steam generator 9 has an opening 18, which is a guiding apparatus 19 and the turbine 20, mounted on the shaft 21, are accommodated in the housing 22. The housing 22 isolates the working parts of the turbine 20 from the condenser 7. To obtain a guaranteed minimum pressure in the steam generator 6 before beginning the steam supply to the turbine 20 in the opening 18 can be installed valve 23 automatically opened by increasing the pressure difference between the cavities of the capacitor 7 and the steam generator 6 to the specified level. The turbine 20 and the guide device 19 is shown schematically and may constitute both one and multi-stage turbine. You can run the turbine without guide vanes. You can pair the turbine and guide vanes through a mechanism to rotate the turbine and guiding apparatus in the opposite direction, in this case, the shaft 21 may be soclety isolated from the environment ( not shown). For the turbine 20 is a condenser 7, the end face of the capacitor 7 with its inner side may be mounted centrifugal pump 24 for pumping the condensate to the steam generator, and the outer side of the pump 25 for pumping the cooling medium. In the case of the Foundation of the steam power installation are teplopodvodyaschey and heat-removing device. Teplopodvodyaschey to the steam generator device 26 brings the heat section of the steam generator 11, teplopodvodyaschey to the steam generator device 27 brings the heat to the section of the steam generator 10. The cooling unit 28 removes heat from the condenser. Teplopodvodyaschey and cooling of the device is shown schematically and can be made in the form of heat exchange devices with different types of heat transfer. Outside the hermetically sealed housing 4 steam power installation is the sensor operating parameters 29 associated with the regulator supply of heating fluid 30, which contains the plunger 31 of magnetic material with a spring 32 supported in the two shoulders of the lever 33, and the valve of the supply of heating fluid 34 to the section of the steam generator 11, and 35 for the partition of the steam generator 10, the opening and closing openings of the supply of heating fluid 36 to the section of the steam generator 11, and the re 6. You can apply the sensor operating parameters of the magnetic device, made of a magnetic material loses its magnetic properties when reaching the environment temperature of the Curie point for a given substance. The sensor operating parameters 29 steam install is on the closest distance from the steam generator. Possibly placing the sensor operating parameters 29 on the steam generator in the form of a continuous Hoop, interacting with the spring loaded pusher 31, rests on the two shoulders of the lever 33, associated with the valves of the supply of heating fluid. There are additional variants of the sensor. The first option involves the fabrication of the sensor operating parameters in the form of a bellows type thermostat, filled with substance, expanding at a certain temperature. The second additional option provides for the fabrication of the sensor in thermostat, made of bimetallic material, reacting to changes in temperature. Third option involves the fabrication of the sensor in the form of a magnetic device, such as an electromagnetic coil core pusher-starting and shutting off when neither (listed additional options sensors operating parameters on the drawing not shown). The sensor operating parameters of steam power plants for greater precision in the working set are very isolated from the hot and cold heat exchange zones by partitions 38, which is also shared zone heating the sections of the steam generator 10 and 11.

Steam power plant operates as follows.

The feature of this steam power installation is to establish a cyclical mode. The first cycle steam power installation begins with the filing of a heating fluid through teplopodvodyaschey device 27 to the section of the steam generator 10, it heats the wall section of the steam generator 10, the liquid section 10 evaporates and through the valves 12 enters the section of the steam generator 9, in which the blood pressure increases to a predetermined value, the valve 23 is opened and the valve 13 is closed. Through the opened valve 23, the hole 13 and the guide device 19 steam enters the turbine 20. Under the action of reactive power steam power installation starts to rotate. The exhaust steam enters from the housing 22 on the cold walls of the condenser 7 to the pump 24 where it condenses. The condensate pump 24 is fed between the housings 22 and 4, and then through the valve 15 is supplied to the section of the steam generator 11. Due to ubiva visitsa and when the temperature reaches the Curie point for this thermomagnetic material sensor operating parameters 29 loses its ability to attract a spring-loaded plunger 31, transmitting force through the two shoulders of the lever 33 on the valves 34 and 35. The supply valve of a heating fluid 34 opens the hole supply of heating fluid 36 to the section of the steam generator 11, and the supply valve of a heating fluid 35 closes the opening of the supply of heating fluid 37 to the section of the steam generator 10. On this first cycle steam power installation is finished. The second cycle steam power installation starts after closing the openings of the supply of heating fluid through teplopodvodyaschey device 27 and the start of the supply of heating fluid through teplopodvodyaschey device 26 to the section of the steam generator 11, it heats the wall section of the steam generator 11, the fluid in the section of the steam generator 11 is evaporated and through the valve 13 is supplied to the section of the steam generator 9, from which steam comes to directing device 19, the turbine 20, and then is condensed in the condenser 7 through the valve 14 enters the section of the steam generator 10. Valves steam installation 12 and 15 during the second cycle steam power installation are closed. Due to the accumulation of cooled condensate in the steam generator 10 in the zone of location of the sensor operating parameters 29 the temperature of the walls of the steam generator falls and the sensor working pair is Leah valves supply of heating fluid 34 and 35. The valve 34 closes the opening of the supply of heating fluid 36 to the section of the steam generator 11, and the supply valve of a heating fluid 35 opens the hole supply of heating fluid 37 to the section of the steam generator 10. On this second cycle steam power installation is finished.
