Hot-rock generating system

摘要

Provided is a hot-rock generating system comprising a filling well formed from the aboveground to the hot rock which exists underground, for causing a heating medium to flow thereinto, a production well formed from the aboveground to the hot rock existing underground, for causing the heating medium heated to flow out therefrom, a generating equipment for converting the heat energy of the heating medium having flown out from the production well, into an electric energy, a catchment bath for containing the heating medium from the generating equipment, and an injection pump for sucking the heating medium from the catchment bath thereby causing the heating medium to flow into the filling well. The hot-rock generating system further comprises a heat exchanger for causing the heating medium having flow out from the production well to flow thereinto.
