MAINTAIN CORRECT ALKALINITY LEVEL OF BOILER

Boiler Alkalinity Chemical

For high silica waters in high pressure steam boilers, it is important to maintain a 3:1 total alkalinity to silica ratio to prevent silica from plating on your boiler tubes. If you are using an all polymer scale prevention chemical it is also important to keep the boiler water pH above 10.5 to ensure the polymer properly works at capturing the calcium and magnesium within the boiler water.
