Boiler Water Treatment - Why is It Important

Boiler water quality is of prime concern to all boiler operators. The process of water treatment in boilers is not limited to producing high quality DM water. The stringent water chemistry requirements of Supercritical power plants makes water treatment in boilers a very critical aspect of power plant operation. This necessitates the use of a high quality water treatment system.

Boiler Water Tests Viking Water Technology, Inc.

Where feed water is softened, the amount of hardness in the softener effluent is a measure of the softener performance and an indication of when the softener needs to be regenerated. The presence of hardness in returned condensate water is an almost positive indication of in-leakage and contamination of the condensate. pH – Boiler and Condensate

Chloride level in Boiler feed water - Corrosion

Hi, I have a question about the allowable level of chloride in boiler feed water. The water has been treated to very low oxygen level (about 6 ppb) and the PH is 12. In my option, there is no concern about the chloride because of no corrosion agents either from oxygen or low PH. Just confirm if this is true?
