  • Steam Boiler: What is Alkalinity?

    The amount of CO 2 produced is proportional to alkalinity. Because of an alkalinity that delivers twice as much CO 2 formed from HCO 3-by CO 3 2-due to interference of bicarbonate is the sum of reactions above. Carbonic acid is usually neutralized with chemical treatment at each steam directly or indirectly through boiler to produce pH around 8.5 to 9.0.

  • 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.

    Total hardness is not to be classified as a type of hardness, but as the sum of concentrations of calcium and magnesium ions present when these are both expressed as CaC03. If the water is alkaline, a proportion of this hardness, equal in magnitude to the total alkalinity and also expressed as CaC03, is considered as alkaline hardness, and the remainder as non-alkaline hardness (See Figure 3.9.5).

    Always use a softener to ensure good Boiler Water Quality. Chemicals are designed to polish away small amounts of hardness that by-passes the softener. 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.

    26/8/2013 · August 26, 2013. 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

    Boiler System – Tips on a chemical program for your boiler system. Most boiler systems today burn natural gas as the primary fuel. Many systems are also set up to burn an alternate fuel if the natural gas supply is curtailed or cut off. In most cases, the alternate fuel is No. 2 fuel oil, a light distillate that is the same as diesel fuel.
