ENERGY GENERATION PLANT (VERSIONS) AND TURBINE EXPANDER Russian patent published in 2015 - IPC F01D15/10 F01D15/08 

FIELD: power industry.

SUBSTANCE: power plant includes a turbine expander containing an expansion section, a pump section and an engine-generator section, which are mechanically connected by means of a shaft. The expansion section is interconnected in a flow manner with the outlet side of the heat exchanger and has a possibility of receiving a steam-like fluid medium flow, rotation of the shaft and creation of an expanded steam-like fluid medium flow. The pump section is interconnected in a flow manner with the outlet side of the condenser and has a possibility of receiving a liquid fluid medium flow, increase of its pressure and provision of circulation of the fluid medium in the above power plant. The engine-generator section has a possibility of electric current output. Some portion of the liquid flow under increased pressure, the circulation of which is maintained by the pump section, is transferred to the heat exchanger, and the other portion is used for cooling of the engine-generator section.

EFFECT: reduction of the size of the supporting surface and reduction of costs is achieved.
