Boiler Scale

Steam boiler cleaning is a routine water system maintenance in which deposits like calcium are removed on the boiler surface through the use of a descaling acid. Impurities tend to accumulate in boilers through constant use which can insulate water from the heat source, especially if heat exchangers in the system use tap water.

Failure to remove impurities can cause scale buildup and impair a boiler‰Ûªs performance.The steam boiler cleaning chemical to be used should fit the specific needs and type of a boiler. For stainless steel boilers, sulfamic acid is the most suitable and potent.

For lightly scaled smaller boilers, using an acidic polymer will gradually remove the scale over time. ChemWorld 1394 is ideal for remove light amounts of scale within small boilers. We also carry concentrated versions of acidic polymers to fit within your 3 or 4 drum water treatment program.

How do I remove boiler scale?
First, before wasting anymore time, you need to determine why your boiler scaled. If you have a scaled boiler the first thing you need to do is to install a softener system. If you can not purchase and install a softener, use a boiler phosphate chemical and feed the chemical at a 7:1 ratio of phosphate to hardness ratio.

If you have a softener and still experienced scaling, your softener is not functioning properly. You must perform hardnes checks on the boiler water, softener water, and feed water. By checking the boiler water hardness, it will provide an overall softener performance that will tell you how the softener performed between softener hardness checks. Remember, a hardness check is a snap shot of one moment of time, checking the boiler water for hardness will provide a period of time look at your softener performance.

Also, if you are not using a softener, always use a phosphate boiler chemical and not just a straight polymer. Phosphate scale is lighter and white in form and sometimes may be flushed out.

You have two options:
  1. You can boiler acid clean the boiler. This option can be expensive depending on the severity of the scale and water volume.
  2. You can use an acidic polymer product that will gradually dissolve the scale over time.

What is Sulfamic Acid?
Sulfamic acid is a white crystalline and water-soluble compound, commonly used in water treatment and synthesis of artificial sweeteners. It has a chemical formula of H3NSO3. It is specially formulated for water system cleaning and maintenance. Product is particularly effective at removing iron and water precipitates. Q-CID S is safe to use and is approved by the USDA for use in federally inspected meat and poultry processing plants.
