Boiler Leak Detection and Ion Exchange Resin Monitoring

Introduction
Boiler Water Quality Management Process
Seawater leak detection is one of the post-condensation water quality management processes that are performed for power station boilers and similar facilities. Damage to the ion exchange resin, which deionizes the supplied water, is also monitored during this process, and both of these applications are executed by a conductivity analyzer.
Process Overview
The above illustration shows where analyzers are used in the boiler water quality management process.
In the measurement point
shown in the figure, two
different signal ranges are needed for deionized water
management and seawater leak detection. The SC450 can
simultaneously generate output signals for two different ranges, meaning that a single unit can perform deionized water
management concurrently with seawater leak detection.
Other applications for this conductivity analyzer include the management of deionized boiler water.
