Total Alkalinity In Steam Boilers

Boiler Water Quality

Silica in boiler feedwater can be a problem in larger steam boiler systems. You must maintain a Total OH alkalinity ratio of 3:1 in high pressure boilers to prevent plating of silica. Alkalinity is a measure of the capacity of water to neutralize strong acids.

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

Treat it right | 2013-08-28 | PM Engineer

Alkalinity in steam-generating boilers is a problem because under heat the alkalinity breaks down to carbon dioxide, which passes with the steam. When the steam becomes condensate, the carbon dioxide becomes carbonic acid, which is corrosive to the steam lines. Water contains alkalinity. The amount depends on the source of the water, be it surface water (lakes and rivers) or groundwater (well
