  • 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.Learn More

    The pH should be maintained between a minimum of 10.5 and a maximum of 11.0 to prevent acidic corrosion of boiler tubes and plates, and to provide for the precipitation of scale forming salts before scale is deposited. Below a pH of 5.0 the water is acidic enough to dissolve the steel boiler plates. Under these conditions the steel gradually Learn More

  • ALKALINITY CONTROL

    Under boiler water conditions, bicarbonate decomposes first to carbonate and then to carbon dioxide . The carbon dioxide leaves the boiler with the steam and forms carbonic acid in the condensate system. The sodium that was attached to the bicarbonate reacts to form alkalinity. In all cases it is the boiler water hydroxyl alkalinity, as measured byLearn More

    4/5/2016 · Boiler pH should be kept between 10.5 and 12.5. Below 10.5, there is insufficient protection from corrosion and hardness compounds are not precipitated in the desired, free-flowing form. Above 12.5 there is the possibility of caustic embrittlement and carryover. Condensate pH should be kept between 8.0 and 8.6. Read MoreLearn More
