METHOD FOR OPERATION OF TWO-CIRCUIT POWER PLANT Russian patent published in 2021 - IPC F02C7/00 F03G7/00 F01K27/00 

FIELD: heat and power engineering.

SUBSTANCE: method for operation of a two-circuit power plant is proposed, including interaction of two closed circuits, auxiliary 1 and main 2 ones, operating in parallel in different directions. Using compressor 1.1 of auxiliary circuit 1, a working body of auxiliary circuit 1 is compressed, and its pressure and temperature are increased, thermal energy of the working body of auxiliary circuit is transmitted to a working body of main circuit 2, mechanical work is extracted from main circuit 2 using turbine 2.3. In auxiliary circuit 1, in front of counter evaporator 1.4, pressure of the working body is reduced in device for reducing pressure 1.3, interaction of circuits is performed using counter evaporator 1.4 located in auxiliary circuit after device for reducing pressure 1.3, and located in main circuit in front of compressor 2.1 and using counter condenser 1.2 located in auxiliary circuit 1 after compressor 1.1, and located in main circuit 2 after compressor 2.1.

EFFECT: claimed method allows for converting thermal energy supplied to the main and auxiliary circuits into mechanical using turbine, while replenishment of the working body is not required, there is no waste in the form of emissions, organic fuel is not required for constant operation.
