What are the Most Commonly Used Inhibitors for Boiler Treatment? 

Proper boiler water treatment ensures efficient and safe boiler system operation and prevents catastrophic failure. A comprehensive treatment program includes pre-treatment equipment, chemical treatment, and proper control of blowdown. 

Boiler water treatment chemical programs use inhibitors to prevent corrosion and scale formation. In this article, we discuss the common inhibitors used in boiler treatment and describe their role in maintaining the health and performance of your boiler system.  


Boiler Corrosion Inhibitors  

Corrosion is a common issue in improperly treated boiler systems. Left unchecked, it can result in system failure. Dissolved oxygen and carbon dioxide in boiler water make-up lead to oxygen pitting, condensate line corrosion, and general system corrosion. System pH or water alkalinity greatly affects the general corrosion rate for metal surfaces. 

The proper use of oxygen scavengers, neutralizing amines or film-forming amines can protect system components from damage. Maintaining the proper alkalinity level or pH balance in the feed water, boiler, and condensate system ensures optimum corrosion control. 


Boiler Scale Inhibitors  

Scale formation is another common issue in boiler systems. Boiler scale reduces heat transfer efficiency, increasing operating and energy costs. Many mineral components that are soluble in the make-up water form complex crystal precipitates on heat exchange surfaces. Corrosion by-products can also precipitate, compounding this issue. 

Despite an effective pre-treatment program, low levels of calcium, magnesium, and iron can concentrate to high levels inside the boiler vessel. Phosphates, phosphonates and polymers safely precipitate, complex or disperse these minerals and prevent scale formation. 


Consult With a Water Treatment Professional 

Proper water treatment programs are essential to prevent scale and corrosion issues. Local water conditions, system operation pressure, use of mechanical deaeration equipment, boiler make, and model all need to be considered in the design of an effective chemical treatment program. The best way to ensure proper system protection is to consult with a professional.
