Low Alkalinity In Boiler Water

Steam Boiler: What is Alkalinity?

2021-2-21 · Alkalinity is defined as water capacity to neutralize acid, or the quantity of anions in water which can neutralize hydrogen cations. Composer alkalinity water are bicarbonate anion (HCO 3-), carbonate (CO 3 2-) and hydroxide (OH-).Borate (H 2 BO 3-), silicate (HSiO 3-), phosphate (HPO 4 2-and H 2 PO 4-), sulfide (HS-), and ammonia (NH 3) also contribute to alkalinity.

Boiler system pH/phosphate program control method

Low-alkalinity boiler water treatment programs exemplified by the pH/phosphate approach have become necessary. Two phosphate-based programs of the pH/phosphate type provide low-alkalinity boiler water treatments. The "TRI-AD" (or "Precision Control") program favors the maintenance of a low, tightly controlled excess of caustic.
