Boiler Chemical



    Boiler water treatment is a type of industrial water treatment focused on removal or chemical modification of substances potentially damaging to the boiler. Varying types of treatment are used at different locations to avoid scale, corrosion, or foaming. External treatment of raw water supplies intended for use within a boiler is focused on removal of impurities before they reach the boiler. Internal treatment within the boiler is focused on limiting the tendency of water to dissolve the boiler, and maintaining impurities in forms least likely to cause trouble before they can be removed from the boiler in boiler blowdown.



The primary function of a boiler water treatment program is to keep heat transfer surfaces (stream generating and associated tubes) free from scale and deposition. The second requirement is corrosion inhibition. Boiler deposits are problematical, as they typically contain undesirable levels of metal oxides, mineral scale, sludge, or various combinations.

The components of boiler tube deposits and the mechanisms by which they form are varied and can be complex. Corrosion generally occurs because of excessive levels of dissolved oxygen but can also develop under tube deposits. Deposits and corrosion can lead to boiler tube failures that result in costly repairs and downtime.

Boiler systems require effective chemical treatment, accurate monitoring and control. WPC provides a full line of boiler water treatment chemicals, testing and control equipment. Our programs increase system efficiency, decrease plant downtime and maintenance costs and extend equipment life.

WPC engineers are the most experienced in the industry, providing the highest level of application and service expertise available. We inspect every phase of your boiler operation including pretreatment systems, feedwater quality, boiler internals, fireside conditions, condensate return, chemical feed and testing and blowdown control systems. Whether for steam boilers or for hot water boiler treatment, WPC specialists are able to provide guidance and recommendations that maximize system reliability at an economical cost.

Our boiler chemicals are in two primary categories:

  • Deposit/Scale Inhibition
  • Corrosion Inhibition
