  • Boiler (power generation) - Wikipedia

    A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.Learn More

  • Flue gas - Wikipedia

    Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived Learn More

  • Flue Gas Recirculation: History and Uses - EnviroPower

    Jun 19, 2019 · Boilers run at a range of fuel rates but need to produce steam at a constant temperature. Heat transfer rates are low at lower fuel rates, producing cooler steam from the superheater. Recirculating flue gas effectively counteracts this problem by increasing the flow rate, and thus heat transfer, through the superheater coils.Learn More

  • PROCEDURE FOR DETERMINING THE THEORETICAL …

    The volume rate of flow of the exhaust gas can be calculated from the equation shown in Procedures for Calculations, Section 3(a). Assumptions must be made as to exhaust gas temperatures, which may depend on any or all of the following: (a) excess air, (b) boiler design, (c) breeching length, configuration, insulation, (d) stack height Learn More
