GEOTHERMAL POWER GENERATION SYSTEM AND GEOTHERMAL POWER GENERATION SYSTEM SCALE PREVENTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a geothermal power generation system and a geothermal power generation system scale prevention method capable of reducing scale components contained in steam introduced into a steam turbine, and preventing a fault due to scales adhering to the steam turbine.SOLUTION: A geothermal power generation system 100 of the present invention includes: a gas-water separator 102 that separates steam S from hot water Wejected from a production well 101; a steam turbine 103 that drives a generator 104 by the steam S; and a first-agent supply unit 108A that supplies a soluble salinization agent 109 to the steam S to transform scale components contained in the steam S to soluble salts.
