  • pH Treatment CleanBoiler.org

    Boiler water can permeate the porous deposit resulting in localize corrosion. When it is coupled with significant heat flux, concentration of the boiler water occurs rapidly speeding the corrosion. The corrosion action is a result of the formation of caustic-ferritic compounds through the dissolving of the protective magnetite film.
