COLD-HEAT POWER GENERATION DEVICE

Title:

COLD-HEAT POWER GENERATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/138766

Kind Code:

A1

Abstract:

This cold-heat power generation device 1 is provided with a thermal power generation device 10, a compressed air energy storage (CAES) power generation device 20, and an output converging unit 50. The facility 10 is provided with an LNG vaporizer 12, a motive power unit 13 which causes natural gas vaporized by the LNG vaporizer 12 to be combusted and converted into motive power, and a main power generator 14 which is driven by the motive power unit 13. The facility 20 is provided with an air compressor 21 which compresses air cooled by the LNG vaporizer 12, an air tank 25 for storing compressed air discharged from the air compressor 21, air heaters 13G, 13H for heating the compressed air supplied from the air tank 25 using the heat generated by the combustion of the natural gas in the motive power unit 13, an air expander 26 which expands the compressed air heated by the air heaters 13G, 13H, and an auxiliary power generator 27 driven by the air expander 26. In the output converging unit 50, an output from the main power generator 14 and an output from the auxiliary power generator 27 are converged.
