  • Feedwater Preheaters | Cain Industries

    Feedwater Preheaters. A feedwater preheater raises the temperature of water before it enters a boiler for steam production. Boilers typically waste 18 to 22% of fuel combustion through exhaust stream gases. This waste heat is an excellent source of energy to preheat feedwater. Cain Industries' exhaust heat exchangers recover an amazing 30 to 50 Learn More

  • 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

  • Why is it necessary to preheat feedwater before entering

    Answer (1 of 9): The solubility of dissolved oxygen and CO2 in water decreases with increasing temperature. At a minimum, boiler feedwater should be heated and vented at full saturation temperature to remove these corrosive gases. In addition, introducing colder water into a boiler under load canLearn More
