Abstract:
(EN) Provided are a method for inhibiting scale including inorganic cations such as, for example, calcium and a geothermal power generating device that can be economically operated while inhibiting the deposition of the scale. The geothermal power generating device comprises: an inorganic cation concentration measuring device (22) for measuring the concentration of bivalent or more inorganic cations in geothermal water collected from a production well (10); a flowmeter (30) for measuring the flow rate of the geothermal water collected from the production well; a heat removal unit (17) for lowering the temperature of the geothermal water; a thermometer (31) for measuring the temperature of the geothermal water after removing heat; a pH measuring device (32) for measuring the pH of the geothermal water after removing heat; a calculation processing unit (28) for calculating the additive amount of a scale inhibitor, according to the value obtained by subtracting the saturation concentration of inorganic cations in the geothermal water after removing heat from the measured value by the inorganic cation concentration measuring device (22), the measured value by the flowmeter (30), the measured value by the thermometer (31), and the measured value by the pH measuring device (32); and a control unit (29) for adding the scale inhibitor to the geothermal water by the amount calculated by the calculation processing unit (28).
