  • Boiler - an overview | ScienceDirect Topics

    II.C.1.a Firetube boiler. The firetube boiler can be described in simple terms as a water-filled cylinder with tubes running through it which provide the escape path for the combustion gases or flue gas. As the flue gas passes through the tubes, the hot gases heat the tubes, which then heat the water to produce steam. The firetube boiler is primarily used in industrial applications.Learn More

  • Oxygenated treatment - Wikipedia

    Oxygenated treatment (OT) is a technique used to reduce corrosion in a boiler and its associated feedwater system in flow-through boilers.. With oxygenated treatment, oxygen is injected into the feedwater to keep the oxygen level between 30-50 ppb. OT programs are most commonly used in supercritical (ie >3250psi) power boilers.Learn More
