PURPOSE:To transport geothermal water and generate electric power at high efficiency by driving a pump by the power generated by a double-phased-flow turbine in which geothermal water is utilized. CONSTITUTION:When a geothermal doble-phased-flow discharged from a pit pump 3 is supplied to a rotary separation type double-phased-flow turbin 6 set up on the ground, a rotary separator 11 is driven and a part of or all of thus obtained power drives a driving shaft 4 via a gear box 7, thereby driving a pit pump 3 placed at the bottom end of the shaft 4. This pit pump 3 directly intakes geathermal water and send it to the ground surface via a pump casing 13. Since the geothermal double-phased flow in the pit bottom is transported through the pump casing 13 as being pressurized up to the pressure corresponding to its temperature, its evaporation is restricted, and the geothermal water can be brought up to the pit inlet whithout changing its temperature at the pit bottom. |
