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.

Steam Boiler Chemicals - These include Oxygen Scavengers, Amines, Phosphates, Polymers, and Alkalinity Builders. Oxygen Scavengers - Most common type is 38%, pH < 4. Other solutions come blended with a cobalt catalyst and alkalinity contributors. These blends are usually 50% dilutions and come in 7 and 10 pH. Using these blends eliminates using

(6) TDS expressed as ppm (mg/l) in steam is proportional to TDS expressed as specific conductivity in the boiler water in each pressure range. For example, 5400 pS/cm in the boiler water is expected to produce 1 ppm (mg/l) TDS in the steam and 1100 pS/cm in the boiler water is expected to produce 0.2 ppm (mg/l) TDS in the steam for boilers operating at 0-300 psig.

1. Priming - This is the ejection of boiler water into the steam take-off and is generally due to one or more of the following: -Operating the boiler with too high a water level. -Operating the boiler below its design pressure; this increases the volume and the velocity of the steam released from the water surface.
