HEAT ELECTRIC STATION

The utility model relates to the field of energy, and more specifically to devices for generating electricity using low-grade heat energy.

Geothermal power plants are known that comprise a block-modular separator, a turbogenerator, a heat exchanger and an air-condensing unit with fans (see, for example, the Kamtchatka Gneral Arrangement Preliminary project, ORMAT Israel, 1997).

The disadvantages of the known devices include the insufficient efficiency of the air-condensate installation and the ability to service the installation as a whole in climatic conditions characterized by increased ice and snow load.

The closest to the proposed technical solution in terms of technical nature and the effect achieved is a geothermal installation containing a separator, a turbogenerator, an air-condensate installation with heat-exchanging sections made in block-modular design, while all the blocks and modules are placed under a light gable roof (see. for example, the Russian Federation at PM No. 9023 according to class F03G 7/00 for 1998).

The disadvantages of the described construction include the low efficiency of the air-condensate installation, due to the relative position of the sections, and significant costs for construction and installation works.

energy while reducing the cost of construction and installation works.

The problem is solved due to the fact that in a well-known thermal power plant containing a steam generator, a turbogenerator, an air-condensing unit with heat-exchange sections placed on a frame according to the proposed utility model, heat-exchange sections are placed around the perimeter of the station and their frames form the supporting structure of the two-level production room of the station, in which is equipped with a bakresiver and a feed pump at the lower level, and a steam generator and a turbogenerator at the upper level, while the output to a turbogenerator working fluid collector is located under the upper level floor, and the plant’s production room is equipped with a hoisting mechanism in the form of a circular beam crane.

Such a design of a thermal power plant allows, thanks to the external location of the tank and the developed pipes, to increase efficiency, the air-condensing unit and the cycle as a whole, and due to the presence of a circular crane beam, reduce the cost of construction and installation works.

In the drawings, the proposed device is schematically represented, in which Fig. 1 shows a longitudinal section of the station, and in Fig. 2 is a top view.

The device contains a closed circuit with a working fluid, which consists of a steam generator 1, including, depending on the working fluid used, a separator, a heater, an evaporator, a superheater (not shown in the drawing), a turbine 2 with an electric generator 3, an air-condensing unit, consisting of heat-exchange sections 4, placed on the frame 5 and communicated through the collector 6 and the transfer pipes 7 with the receiver tank 8 and the feed pump 9. The frame 5 of the heat exchange sections 4 forms

the supporting structure of the production room 10 of the station, equipped with a roof 11 and a floor of the second level 12, under which a manifold 6 and distribution pipes are placed 7. Each heat exchange section is equipped with a fan 13. In the center of the production room 10 there is a lifting and transport mechanism 14 with internal 15 and external 16 crane beams used for construction and installation works during the construction process and repair and maintenance work during the operation of the station.

The device operates as follows.

Heat enters the steam generator 1 from an external source, for example, hot thermal fluid (water, steam). In the steam generator 1, the working fluid (RT), which circulates in the working circuit of the thermal power plant, is transferred to the vapor state and enters the turbine 2, where, expanding, it performs work by rotating the electric generator 3. The exhaust of the turbine 2 is brought together with a steam distribution manifold 6, from which pipes 7, the pre-cooled RT is sent to individual groups of heat-exchange sections 4 of the air-condensing unit. An air-cooled RT moves from top to bottom inside the sections 4, condenses in the lower part of the sections 4 and is collected in the receiver tank 8 and enters the feed pump 9, which compresses the RT and feeds it into the steam generator 1. Thus, a traditional thermodynamic cycle is realized, with expansion of steam in the area of the legal boundary curve of the TS diagram.

The presence of a crane 14 with internal 15 and external 16 crane beams is the basis of the power structure of the production room 10 with a roof 11 and provides the process of erecting the production room 10, installation of equipment and repair and maintenance work during operation of the thermal power station.
