What is boiler water PH? And why so maintained? - …

> Natural water is usually between 6.5 and 7.5 pH. A common recommendation is to maintain boiler water at 8.5 pH.Acidic water is corrosive. Alkalinic water is more prone to scaling.Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3

pH Treatment. Introduction. A pH less than 7 is acidic, and a pH greater than 7 is basic (alkaline). Each whole pH value below 7 is ten times more acidic than the next higher value. For example, a pH of 4 is ten times more acidic than a pH of 5 and 100 times (10 times 10) more acidic than a pH of 6. When the boiler water pH drops below

If hydrazine (N 2 H 4) is not used, sodium sulphate (Na 2 SO 4) can be used instead, and the excess should be 30 – 60 ppm.. In cases where other kinds of oxygen binding agents are used, it is recommended that an excess of oxygen binding agents can be measured and indicates that no oxygen has been dissolved in the boiler water.

If the pH is lower than that, the water will start eating the pipes. If it’s higher than that, the water won’t corrode metal, but it may begin to foam, and that’s not good. Hold that thought for a moment. You’re on a job and you have a steam boiler that’s taking on a lot of feed water because the system has leaks.

Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica
