Title:
THERMOELECTRIC POWER GENERATION SYSTEM EXTRACTING UNDERGROUND COAL FIRE THERMAL ENERGY
Document Type and Number:
WIPO Patent Application WO/2018/072286
Kind Code:
A1
Abstract:
Disclosed is a thermoelectric power generation system extracting underground coal fire thermal energy, comprising a coalfield fire area (1), coalfield drill holes (2), underground thermal conductive pipelines (3), and a thermal conductive container (4), wherein the thermal conductive container (4) is provided with a pressure relief device (5). Further comprised are a group of thermoelectric power generation pieces (6) and a storage battery (7). The group of thermoelectric power generation pieces (6) is provided on an outer side wall of the thermal conductive container (4). An outer side of the group of thermoelectric power generation pieces (6) is provided with a cold end radiating tube (8). The group of thermoelectric power generation pieces (6) is located between the thermal conductive container (4) and the cold end radiating tube (8). The cold end radiating tube (8) is connected to a radiator (9) for heat radiation and a pump (10).
