TWO-CIRCUIT POWER PLANT Russian patent published in 2022 - IPC F01K23/08 F01K25/10 

FIELD: power generation.

SUBSTANCE: The claimed solution relates to power generation, in particular to devices that convert the energy of the working fluid into mechanical or electrical energy, and can be used in the electric power industry, thermal power engineering, machine tool construction, automotive and other industries. A two-circuit power plant that contains a generator, starter, turbine and two compressors of the main and auxiliary circuits placed in series on one shaft, as well as two closed circuits: an auxiliary and a main one with a working body in each, while the circuits are designed to interact with each other. A closed main circuit has a compressor of the main circuit connected in series within its circuit, an intermediate heat exchanger, a counter heat exchanger-a condenser of the auxiliary circuit, an air heat exchanger heated by an external heat source, a turbine, an intermediate heat exchanger, a counter heat exchanger-an evaporator of the auxiliary circuit. The closed auxiliary circuit has a compressor of the auxiliary circuit connected in series, a counter condenser, an air heat exchanger-condenser, a pressure reducing device, a counter evaporator, an air heat exchanger-evaporator.

EFFECT: The present invention simplifies and ensures the efficiency of the design, in which no overheating of the working fluid is required, no constant replenishment of the working fluid in the auxiliary circuit is required, which eliminates waste in the form of emissions of the spent working fluid.
