Waterside scale deposits in steam boilers can have a dramatic impact on fuel efficiency, boiler structural integrity, and maintenance costs for the steam plant operation. In severe cases, waterside scale accumulations can cause boiler tube failures due to overheating, restriction of effective water circulation, as well as under deposit corrosion mechanisms. The primary measures to prevent these failures are effective make-up water pretreatment, internal chemistry control, and effective chemical treatment practices. Regarding the most recent advances in chemical boiler treatment, SUEZ has recently introduced a novel terpolymer chemistry control of waterside scale deposits in steam boilers in the low-to-intermediate pressure ranges up to 900 psig.
