  • Boiler Feed Water (BFW) Corrosion | Inspectioneering

    Boiler feed water (BFW) corrosion is mostly the result of dissolved oxygen in the feed water, but is also related to the quality of the BFW and the quality of the treatment system. If the treatment system is effective, then a layer of iron oxide (magnetite) will provide the protection needed to minimize boiler corrosion. If the treatment is not effective or the quality varies from time-to-time Learn More

  • US4173949A - Feedwater preheat corrosion control system

    An improved arrangement for preheating feedwater in a steam boiler system prior to the feedwater entering a fuel economizer in order to prevent corrosion due to condensation of flue gas in the fuel economizer and in the exhaust of the boiler system. The feedwater, prior to entering the fuel economizer, is heated in a preheater with a portion of steam from a boiler.Learn More
