Boiler Water Treatment Guidelines; Columbia Boiler Co

The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover. A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided. Values higher than this can lead to

Steam Boiler: What is Alkalinity?

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.
