Title:
WATER QUALITY DIAGNOSIS METHOD
Document Type and Number:
WIPO Patent Application WO/2022/163613
Kind Code:
A1
Abstract:
This water quality diagnosis method comprises: a step for acquiring a measured value of the electric conductivity of sample water and a measured value of the pH of the sample water, the sample water being derived from steam or circulating water collected from a steam turbine plant using ammonia as a water quality adjusting agent; and a determination step for determining whether water quality in the steam turbine plant is abnormal, by at least using a first determination condition of whether or not the measured value of the electric conductivity and the measured value of the pH are included in a first determination region set in a first correlation map of the electric conductivity and the pH in consideration of a concentration range of a carbonic acid that can be dissolved in the sample water.
