Steam and Water Sampling System

System Description

In industrial plants such as fossil power, nuclear power, HRSG, co-generation, auxiliary boiler unit etc., where cycling water is the process medium for producing electricity, steam, heat or combination of those, maintaining the quality of water as specified is critical task for guaranteeing the design life and performance of the plant.

Objective of Steam and Water Sampling System is to monitor the quality of sample steam and water that are transported to the system from various points of plant. Samples brought to the system are conditioned first so that their pressure, temperature, flow rates etc. are agreeable with those required by the on-line analyzers installed in the system and also for manual sample taking.

Type of on-line analyses to be performed in the system depends on application and decision of plant design engineers. pH, conductivity and dissolved oxygen values are most frequently measured and silica, sodium, chloride and Fe ion concentrations are additionally monitored when needed. Analysis results are indicated and recorded at the system control panel and/or transmitted to remote facilities for determination whether plant chemistry is being maintained as scheduled and also whether significant components of the plant cycle are being operated in good conditions.
