PURPOSE:To improve the utilization of geothermal energy by feeding a portion of hot water to failed well or deteriorated well. CONSTITUTION:A geothermal power plant 1 will feed a portion of hot water separated from gas-water mixture ejected from a geothermal well 3 by a gas- water separater 4 and returned to the underground through a return well 5 to a failed well or deteriorated well 6 through a piping 7. A pit pump 8 provided in the failed well or deteriorated well 6 will pump the mixture of hot water in the well and the hot water injected from the outside and feed through a piping 9 to a binary cycle power plant 2. Since necessary amount of hot water supply can be assured easily through utilization of hot water in the failed or deteriorated well, the utilization of geothermal energy is improved as a whole. |
