Scaling in boilers - LenntechContinue turning on and off the boiler to maintain the temperature in the range of 100-130F. Check pH every 15 minutes; (should be 1 or 2). If higher, add Scalzo to depress the pH back to 1-2 pH. Continue step 5 until pH remains at 1 or 2 for 120 minutes or more, depending on scale build-up. The system is then as clean as will be with the iron test - Search iron testThe iron content of the boiler feed water is determined by continuously obtaining a sample of the,boiler feed water, continuously maintaining the water sample at ga controlled pH by the addition of chemicals thereto and thereafter oxidizing the iron in the boiler feed -water sample.

Fouling formation and under deposit corrosion of boiler …29/4/2020 · The main purpose of boiler water treatment is to have a scale free and corrosion free boiler internals. To prevent corrosion in boilers the boiler tubes needed to be passivated. Corrosion occurs when such passivated layer of magnetite becomes unstable or when chemicals are allowed to come between it and the base metal.test of iron - Search, Compare and SaveIron deposits in boilers are most often magnetic. They are soluble in hot acid giving a dark brown coloured solution. If unchecked, scaling causes progressive lowering of the boiler efficiency by heat retardation, acting as an insulator. Eventually, scale built-up will cause the tube to overheat and rupture.
