  • 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

  • Air preheater - Wikipedia

    In the tri-sector design, the largest sector (usually spanning about half the cross-section of the casing) is connected to the boiler hot gas outlet. The hot exhaust gas flows over the central element, transferring some of its heat to the element, and is then ducted away for further treatment in dust collectors and other equipment before being Learn More

  • How Do Burner Combustion Control Systems Work? - CrossCo

    To prevent this, burner CCSs implement cross-limiting. In its most simple form, the air flow SP is the greater of the boiler master and the actual fuel flow PV (%) and the fuel flow SP is the lesser of the boiler master and the actual air flow PV (%, after it is run through the FAR PWC and O 2-trimmed). This forces air to lead on firing rate Learn More
