Testing Alkalinity In Boiler Water - Taylor

Testing Alkalinity In Boiler Water. Alkalinity is a key control parameter for boilers (outside of the prescribed operating range, it can lead to corrosion, caustic metal embrittlement, and carryover) and cooling water systems (where it has a significant effect on chemical treatments for …

Its caustic concentration can be as high as 10,000-100,000 ppm. Careful control of boiler water chemistry can prevent caustic gouging. If the “free hydroxide alkalinity” is set too high or uncontrolled, then caustic gouging may result. Prevention of porous deposit formation (such as iron oxide) eliminates a place for caustic gouging to occur.

What is the reason for keeping a boiler feed water pH

Chemical reactions happen very fast at elevated temperatures. Because of this we try to operate the boiler at the lowest possible corrosivity relative to pH (Note: this is only for boiler operating without high purity feedwater). That point is aro

2020-3-29 · Maintenance of proper pH throughout the boiler feedwater, boiler, and condensate systems is essential for corrosion control. Most low-pressure boiler system operators monitor boiler water alkalinity because it correlates very closely with pH, while most feedwater, condensate, and high-pressure boiler water requires direct monitoring of pH.

The Importance of Boiler Water and Steam Chemistry

Common causes of foaming are excessive solids or alkalinity, and the presence of organic matter such as oil. Keeping dissolved solids below the concentration that causes foaming requires continuous or periodic blowdown of the boiler. High boiler water alkalinity increases the potential for foaming, particularly in the presence of suspended matter.

2014-5-15 · and water quality, a typical high pressure boiler fed with de-mineralized water would tend to run with low concentration of 1 to 5 mg/l range, while a lower pressure boiler running with softened water might go to 25 mg/l. High alkalinity can occur either as a result of steam blanketing or by localized
