GEOTHERMAL ASSISTED POWER GENERATION

摘要

In a coal fired power plant (17) incorporating a feed-water heater (10), energy is provided to the feed-water heater by pumping geothermal hot water through supply and return pipes (15, 16) from a geothermal reservoir (14) located beneath an adjacent coal seam (19). The coal seam acts as an insulating layer, increasing the temperature of the geothermal reservoir (14). Solar heat collectors (21) and (25) can also be provided to boost the temperature of the geothermal hot water and/or the feed water.
