Boiler Water Treatment

You must treat steam boilers different then hot water boilers.  Steam boilers are boiler that produce steam.  Hot water boilers do not product steam, rather they recirculate hot water. This is important in selecting a proper boiler water treatment program.

Steam Boilers Chemicals: Boiler Water Treatment

Sulfites, Alkalinity, Amines, and Phosphates or polymers are used essential to maximize the life of a low pressure boiler.

Alkalinity is used to increase the boiler water pH to above 10.5. This serves three purposes. pH above 10.5 will decrease your overall corrosion rates, it will keep a 3:1 ratio of total alkalinity to silica, and it allows the polymer to react with calcium. A 3:1ratio keeps silica from plating in the boiler. A low pH will result in an over general corrosion appearance on your boiler tubes.
Sulfites are used to remove any dissolved oxygen from the water. Dissolved oxygen enters the boiler in make up water or as air is sucked into the system. Dissolved oxygen is extremely corrosive to your tubes and localized pits will form, ultimately resulting in premature tube failure. Maintain a 20 to 40 ppm residual of sulfite in your boiler water.

Amines are used to increase the condensate pH to a range of 7.8 to 8.7. When generating steam, carbonic acid forms and as a result your steam pH is low. Amines are volatile and when introduced into the steam header or boiler water, amines will increase the condensate pH. A low pH will lead to excessive condensate pipe corrosion.

Phosphates and polymers are used to react with any calcium in the water. The polymer attaches itself to the calcium. The polymer and calcium then is able to exit the boiler through the surface or bottom blowdown. Phosphate reacts with the calcium and sinks the calcium to the bottom of the boiler. When using phosphates you must perform boiler blowdown daily to release the phosphate and calcium. Failure to use a polymer or phosphate will result in calcium build up on the tubes or as some call it boiler scale. This will decrease the over boiler efficiency and will drastically increase your fuel cost.

Remember water expands 100,000 times when changing from a liquid to vapor phase. A typical home water boiler 30 gallon system has enough energy to throw a 2,000 pound car over 100 feet in the air if catastrophically failed. Every year people die from not implementing a basic water treatment program.
That is boiler water treatment made simple for less then 200 psi boilers.

Boiler Chemical

BC 1287 is an All-in-One All-Polymer internal treatment product. Boiler Chemical 1287 includes polymer for deposit control and sulfite for removing oxygen from the boiler water. There is no amine (condensate treatment) in this product.

Also, listed is an Optional Supplemental Oxygen Scavenger.  A "Two Drum" treatment chemical program are often implemented in high makeup water systems or where no deareator is present.

  • Improves Boiler Reliability and Cleanliness
  • Single Drum Product for Ease of Use
  • Utilizes Copolymer for Excellent Control of Hardness and Iron Deposition
  • Polymer Stable over a wide range of Pressures and Temperatures

INGREDIENTS:
  Sodium Sulfite, Sodium Hydroxide, Phosphinocarboyxylic Acid Polymer, Sodium Lignosulfonate

OS 1537LF
OS1537LF is a neutral pH sulfite (7.0 pH) solution which, when added to boiler feedwater, removes dissolved oxygen. OS 1537LF contains a catalyst that increases the rate of reaction with dissolved oxygen.  By acting as an oxygen scavenger, OS 1537LF is used to control corrosion and pitting caused by the presence of dissolved oxygen.

INGREDIENTS: Sodium Sulfite, Potassium Sulfite

All-In-One Boiler Chemicals


All-In-One Boiler Chemicals are an easy way to reduce the amount of chemical on-site as well as an easy way to treat your boiler system.  This grouping of Boiler Chemicals come with all the necessary boiler components to effectively treat a boiler system.  It is not an efficient way to treat large boilers.  In some cases, you may consider using a supplemental straight sulfite product in conjunction with an all in one chemical. There are two basic Boiler Chemical products in this category, one with amine and the other without Amine.

What is Boiler Chemicals

Boiler Chemicals are used to prevent scale and minimize corrosion. The ultimate goal is to reduce water usage, save on energy and to extend equipment life. Below are some of the frequently asked Boiler questions:
