Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3) and hydroxyl (OH) ions in the water. pH and alkalinity ratings are NOT the same and are NOT proportional. pH is rated on the Scale and alkalinity is measured in parts per million (ppm). A typically recommended alkalinity rating is 140 – 700 ppm for boilers operating below 300 psi.

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
