ARCTIC THERMAL POWER PLANT Russian patent published in 2024 - IPC F01K25/10 

FIELD: power engineering.

SUBSTANCE: disclosed solution relates to power engineering, in particular to devices that convert energy of working medium into mechanical and/or electrical energy, and can be used in electric power industry, heat power engineering, in machine building, in automotive industry and other industries in climatic zones with cold climate. Arctic thermal power plant includes a pneumatic engine containing an inlet assembly and an exhaust assembly, as well as an output shaft interacting with the drive mechanism of this pneumatic motor for the obtained power takeoff. Pneumatic motor outlet unit is connected along the main circuit of the pipeline, in which the working medium circulates, to at least one air heat exchanger providing cooling of the working medium to the temperature close to the street temperature. Air heat exchanger is connected along the main circuit of the pipeline to the compressor inlet unit for transfer of the working medium cooled to close to the street temperature. Compressor outlet unit is connected along the main circuit of the pipeline to at least one liquid heat exchanger, which provides heating of the working medium circulating in the main circuit of the pipeline, and further connected to the pneumatic motor inlet unit for the heated working medium transfer, for the pneumatic motor operation and the obtained power transfer to the output shaft. Liquid heat exchanger is configured to receive and transfer thermal energy along a heating circuit, the ends of which are immersed in the water body below its freezing depth, where water from the water body circulates in the heating circuit by means of a circulation pump.

EFFECT: simplified design of arctic thermal power plant at its high efficiency.
