Boiler Water Treatment - Why is It Important ? - Bright Hub …
2011/4/30 · Four Reasons Why Boiler Water Treatment is Important. There are four main reasons why water quality is so important. Impurities in water form scales. Water contains dissolved salts, which upon evaporation of water forms scales on the heat transfer surfaces. Scales have much lower heat transfer capacity than steel: the heat transfer coefficient

Plant Engineering | Maintaining boiler safety
A chelant boiler water treatment program that is not properly maintained to ensure proper dosages of chelating chemicals can create problems with consequences these chemicals are injected to prevent. Chelant corrosion or attack develops only when excess concentrations of sodium salt are maintained substantially above the control level for an extended period of time.
