SYSTEM AND METHOD OF WASTE-HEAT RECOVERY Russian patent published in 2017 - IPC F01K23/04 

FIELD: electricity-producing industry.

SUBSTANCE: system, which uses Rankine cycle, is designed with a possibility of waste heat transformation into the mechanical and/or electrical energy. In respect of one aspect, the system, implemented according to the invention, has a new elements configuration of the traditional system, which uses Rankine cycle: of the pipelines, channels, heaters, expansion engines, heat-exchangers, capacitors and pumps. In respect of the other aspect, the system, which uses Rankine cycle, is implemented in such a way that the primary flow with waste heat is used for the actuating medium first flow vaporation, and the total depleted in heat flow with waste heat and the first part of the expanded second flow of the vaporized actuating fluid medium are used for the heat gain, which is provided by the expanded first flow of the vaporized actuating fluid medium when producing the second flow of the vaporized actuating fluid medium. The system, which uses Rankine cycle, is designed with a possibility of using the carbon dioxide in the capacity of the actuating fluid medium.

EFFECT: upgrading of the efficiency of the energy recovery from the waste heat source.
