PURPOSE:To enable to deal with the heat exchange between two liquids having different corrosion mechanisms to the material of a vessel by a method wherein an evaporator of geothermal water and a heater of river water are separately provided and each vapor phase part of the evaporating chambers of the evaporator and that of the heating chambers of the heater are communicated to each other with a steam pipe in the hot water producing plant for geothermal generation. 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 arrow 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 geothermal water drain pipe 30. On the other hand, the river water B is supplied from a river water storage tank 13 through a supply pipe 50 into the heater 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 tankds 17. In the course that the river water passes through the heater 19, H2S contained in the steam is discharged from the vent hole of the heating chambers 39 to the open air as indicated with the arrow G. |
