If water is fed to boiler as it is, with no appropriate treatment, components contained in the boiler feed water can cause various problems.

  • Cations (calcium, magnesium, iron, sodium, etc.): scale, corrosion, carry-over
  • Anions (bicarbonate, chloride, sulfate, nitrate): corrosion
  • Non-ions (silica, free carbonic acid, resolved oxygen): scale, corrosion

In order to prevent such problems and operate your boilers efficiently and safely, it is essential to treat the feeding water with, for example, a water softener or a demineralizer, and to add boiler water treatment chemicals properly.

Boiler water treatments may vary widely depending on the conditions of the boiler plant, such as the boiler model, operating conditions, and supply water quality. We will suggest the water treatment most appropriate to your needs.

Problem in Boiler Plants

  • Corrosion on a flue and smoke tube boiler

  • Corrosion on a water tube

  • Corrosion on a once-
    through boiler

  • Build-up of scale on a flue
    and smoke tube boiler

  • Inside a boiler operated
    safely with water

  • Corrosion on a condensed
    water pipe

  • Effects of using water
    treatment chemicals for
    corrosion prevention on
    a condensed water pipe
