Abstract

OF THE DISCLOSURE WATER QUALITY MONITORING SYSTEM AND STEAM TURBINE SYSTEM INCLUDING THE SAME AS WELL AS WATER QUALITY MONITORING METHOD A water quality monitoring system is disclosed including a sampling pipe that acquires steam that passes a bleed pipe that bleeds steam from a low pressure turbine to which steam of low pressure is supplied from among steam turbines, a steam inlet tank into which the steam acquired by the sampling pipe flows, a water quality measurement apparatus that measures the water quality of condensed water condensed from the steam flowed in the steam inlet tank, and a water quality diagnosis apparatus that diagnoses the water quality of the condensed water using a result of the measurement of the water quality measurement apparatus. The steam inlet tank is installed at a location higher than that of the water quality measurement apparatus such that the water quality measurement apparatus measures the water quality of the condensed water boosted to the atmospheric pressure utilizing the head difference.
