PURPOSE:To enable to deal with the heat exchange between two liquids having different corrosion mechanisms by a method wherein an evaporator of geothermal water and a heater of river water are separately provided and connected with steam pipes in the hot water producing plant for geothermal generation and the geothermal water had done with the predetermined evaporation is drained by its own water head. CONSTITUTION:The geothermal water is sent to hot water storage tanks 11 as indicated with the arrow A and removed H2S content up to a certain point and as well as discharged from a vent hole as indicated with the arror F. The geothermal water left the hot water storage tanks 11 is supplied to the evaporator 18 and evaporated successively in each of the evaporating chambers 22 and naturally drained into a water storage tank 15 from the final evaporating chamber 22e through a drain pipe 30. On the other hand, the river water B is supplied from a water storage tank 13 through a supply pipe 50 into the heaters 19 by means of a pump 14. After that, the river water is heated by steam E entering from the evaporator 18 in the heating chambers 39 of the heater 19 and transferred successively in each of the heating chambers 39 by means of respective pumps 54 and sent from a hot water draw-off pipe 55 through the pump 54 to hot water storage tanks 17. In this case, H2S is discharged from the vent hole 74 of the respective heating chambers 39 to the open air as indicated with the arrow G. |
