Sampling System
Steam & Water Analysis System (SWAS)
CC,SC,DO, pH
Degassed Acid Conductivity, Sodium, Silica
CC,SC,DO, pH
Purpose of Sampling System
Steam & Water which is used for High Temp. and Press. Boiler should be maintained as High Quality.
Improper process water treatment will cause Scale, Corrosion, Carry-over problem and it will be the main reason of boiler trouble.
In Power Plant, Steam/Water circulation process, Water treatment process (RO, Filtering System) should be monitored instantly to detect the inflow of dirty particle and also the operating condition.
However, online monitoring is not possible for Steam/Water mostly due to the high temp. & pressure.
Sampling System is required to conditioning those samples to be suitable condition for the monitoring online.
