      Water Handbook - Preboiler & Industrial Boiler Corrosion

      Maintenance of proper pH throughout the boiler feedwater, boiler, and condensate systems is essential for corrosion control. Most low-pressure boiler system operators monitor boiler water alkalinity because it correlates very closely with pH, while most feedwater, condensate, and high-pressure boiler water requires direct monitoring of pH.

      Magnetite causing a hot water boiler to crack — Heating

      Sludge -- including magnetite -- can indeed kill a boiler by impeding circulation, causing localized hot spots and thus cracking. That's pretty well known. However, first, there are no special properties of magnetite which specifically do that. It's a component of sludge (I might note in passing that this is not true of certain pumps; there the
