The invention relates to power engineering, namely, steam turbines, and can be used in various drive systems for converting thermal energy into mechanical energy.

For the assessment of novelty and inventive step of the proposed solution consider a number of known technical devices of similar purpose.

Known energy installation comprising a set of closed-loop working fluid steam generator, turbine generator, condenser pipe inlet air and condensate-feedwater pump [1].

This unit, like all others who have similar traditional layout, has several disadvantages.

Steam generator installation has limited production due to low speed of ascent of the bubbles of vapor of the working fluid and the vapor film between the walls and the working fluid. In the condenser installation required the removal of a large amount of heat that makes use of gramond the pumping of condensate also complicates the design of the installation, which turns out to be cumbersome and resource-demanding.

In the existing prior art steam power installation, in which, to reduce their size and weight, and implemented a variety of constructive ways of combining individual elements of the steam generator to the turbine, the steam generator to the condenser and so on).

Known, for example, steam power installation comprising a coaxially mounted on the base in the bearings of steam generator, turbine, condenser and condensate pump, connected in series in a closed pressurized loop, the condenser and the steam generator is made in the form of bodies of revolution, the capacitor attached to the steam generator and offset from the axis of rotation, while the turbine wheel and impeller condensate pump attached to opposite ends of the steam generator [2].

The rotation of such a setup is possible only in the presence of guide vanes, which for some reason is mentioned only in the additional claim. The need for guide vanes connected to ground through a fixed compacted shaft leads to depressurization of the installation, the need to have reliable sealing, Oakvale installed on the base in the bearings of the steam generator, turbine, condenser and condensate pump, connected in series in a closed pressurized loop, and the steam generator and condenser are made in the form of bodies of rotation, the capacitor attached to the steam generator and offset from the axis of rotation and nozzle guide device attached to the steam generator [3].

By the greatest number of similar features and achieved when using the result of this technical solution is chosen as the prototype of the present invention.

The disadvantages of the prototype, which does not allow us to achieve our goals, are disadvantageous working conditions of the condenser, due to the fact that when the water vapor with cooling refrigerant, such as air, is blown away and is lost a large amount of heat. This leads to a substantial decrease in the efficiency of the installation as a whole.

The objective of the invention is to increase the efficiency of the facility by ensuring the utilization of the residual heat of the exhaust steam.

The essence of the invention is expressed in the following essential features sufficient to achieve the above technical result.

According to image regenerator, the turbine and condenser connected in series in a closed pressurized loop, and the steam generator and condenser are made in the form of hollow bodies of revolution, and the capacitor is offset from the steam generator to the axis of rotation, the steam generator is communicated to the pipe with nozzle guide vanes fixed to the hermetically sealed casing of the condenser, with part of the housing of the condenser is made in the form of condensation heat conducting wall, the cavity capacitor in the area of the condensate collecting primary working fluid through a pipe communicated with the cavity of the steam generator and turbine, with the possibility of free rotation is placed inside the cavity of the condenser, the condensation wall is made hollow and filled with additional working fluid having a boiling point less than the primary working fluid, while the plant is equipped with an additional heat exchanger for additional cooling of the working fluid, is attached to the unit body and is made in the form of additional steam power installation, similar to basic, and hollow condensing wall main steam installation is an additional steam generator steam power plant, condensing wall which is udaetsya set of essential features, providing technical result in all cases to which the requested amount of legal protection.

In addition, the proposed solution has optional features that characterize its special cases, the specific form of its material embodiment or special conditions of its use, namely: the unit can be equipped with a superheater to superheat the additional working fluid; a turbine main and additional installations with horizontal axis can be equipped with deblassie goods.

The technical solution is new, as is characterized by the presence of a new set of features missing for all we know the technical objects of similar purpose.

Direct technical result that can be obtained with the implementation of the totality of symptoms, is that because the additional working fluid has a boiling point lower than that of the primary working fluid in the vapor core installation does boil additional working fluid, the effectiveness of the heat sink is approximately 10 times higher in comparison with the heat sink on dekinai wall. In addition, pairs of additional working fluid performs useful work in additional steam installation.

This technical result is not a consequence of the known properties shown separately next known from other technical objects characteristics, such as nozzle apparatus, condensing wall, a hollow body of rotation, etc., and is the only property of the entire offer in the first claim set of features, including such new features as the mutual arrangement and interrelationship of all elements of the installation.

Obtaining mentioned technical result provides the appearance of the object of the invention in General, the number of new useful properties, namely: improving efficiency by providing optimal conditions for condensing exhaust steam and additional mechanical energy to install. Specified allows you to accept the proposed solution meets the criterion of "inventive step".

The drawing shows the installation, axial section.

The apparatus comprises a steam generator 1, the turbine wheel 2 and the condenser 3. The steam generator 1 is covered by the heater, the United is 5. The capacitor 3 has a hollow heat-conducting condensation wall 6 and the pipe 7 communicates with the steam generator 1. Additional steam power installation has a nozzle guide device 8, the impeller of the turbine 9, a capacitor 10 with condensation heat conducting wall 11. Additional steam power plant has a design similar to the design of the master installation, with its steam generator is hollow condensing wall 6 of the main installation. The pipeline 12 reports the capacitor 10 with the cavity of the condensation wall 6. Installing fixed in the bearings 13 on a common axis 14. Impeller turbines 2 and 9 secured in the bearings 15 and 16 and are rotated in opposite directions relative to the unit body.

The device operates as follows.

The main working body of the steam generator 1 via line 4 is supplied to the guiding device 5 and to the blades of the impeller of the turbine 2. However, the installation gets a moment of forces, bringing her body into rotation. Turbine 2 starts to rotate in the opposite direction. The blades of its impeller is made with the profile, providing turn exhaust the steam jet towards the warmth of the falling direction of condensation wall 6, providing additional moment, torque setting. Formed in the wall 6 of the main condensate of the working fluid due to its centrifugal forces on the pipeline 7 is returned in the peripheral zone of the cavity of the steam generator 1.

Additional working fluid condensation in the cavity wall 6 has a boiling point lower than that of the primary working fluid, which in its boiling point is increased efficiency of the heat sink. Pairs of additional working fluid enters the nozzle guide device 8 and the impeller blades of the turbine 9 additional installation, which also have a profile that provides the direction of the steam jet additional working fluid for condensing the wall 11. The condensate pipe 12 due to centrifugal forces is returned in the peripheral zone of the cavity condensation wall 6. This is due to the fact that the condensation wall 11 and other main elements of the additional settings are shifted to the common axis relative to the respective elements of the main installation.

Pairs of additional working fluid and transfers energy to the blades of the impeller 9. When this occurs the moment of forces, which combine with the point C is helicene effectiveness of the proposed steam power plant can be applied additional superheater (not shown) for additional superheat of the working fluid with its subsequent submission to a guiding apparatus 8. For additional heating of the working fluid can be used residual heat for steam generator primary installation. In some cases, to simplify the design of the facility may apply the non-balances secured to the rims of wheels of the basic and additional installations that prevent their rotation and increase the moments of forces, torque the body of the device.

The proposed installation may have more than two similarly arranged stages, in each of which the working fluid should have a boiling point less than in the previous stage, and the capacitor must be shifted to the common axis.

The industrial applicability of the claimed technical solution is not in doubt, as it can be implemented separately using known means.

Currently are testing a prototype of the proposed facility, preliminary results of which confirmed the performance and high efficiency.
