摘要

PROBLEM TO BE SOLVED: To provide a geothermal power generation steam property monitoring device, a geothermal power generation steam property monitoring method, and a geothermal power generation system control method for removing Sions of sulfur compounds in steam to eliminate obstacles of an analysis so as to enable continuous steam monitoring, and for realizing unmanned monitoring.SOLUTION: A geothermal power generation steam property monitoring device includes: a first cooling unit 14A cooling sampled steam 11A sampled from a steam pipe 12 for supplying steam for geothermal power generation to provide steam drain; an agent supply unit 16 supplying an oxidation agent 15 (for example, sulfuric acid or hydrogen peroxide, described in an embodiment) to the steam drain; a mixer 17 mixing the oxidation agent 15 with the steam drain in a natural accumulation manner; a reaction acceleration device 18 accelerating an oxidation reaction of mixture water 13A in which the oxidation agent 15 is mixed with the steam drain in the natural accumulation manner; a first analyzer 19A analyzing a property of the mixture water 13A after reaction acceleration; and a second analyzer 19B analyzing a property of the steam drain before an adjacent treatment.
