pH Treatment | CleanBoiler.org

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.

Getting to the Bottom of the Boiler Blowdown Procedure

Chemical treatments and continuous surface blowdowns are commonly used to eliminate solids at the same rate as they are added from the feed water. Recommended maximum TDS levels depends on the type of boiler - normally ranging 2000 - 10000 ppm. TDS can be monitored by measuring the electrical conductivity of the boiler water.

The importance of pH in steam-boiler water

24/6/2014 · The challenge starts when the water boils because carbonates and bicarbonates break down and leave the boiler as carbon dioxide. This gas flows through the system with the steam, and if you're not venting the system well, the condensate will absorb the carbon dioxide as the steam gives up its latent heat to the pipes and the radiators.
