  • Flue Gas - an overview ScienceDirect Topics

    The flue gas exits the cyclones to a plenum chamber in the top of the regenerator. The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam.

  • CONDENSATION OF FLUE GASES IN BOILERS - WSEAS

    2006-9-29 · Dry flue gases losses are typically 4% or greater depending on exit flue gas temperature. This loss is caused by the heat carried out by hot nitrogen, carbon dioxide, sulfur oxide and excess oxygen. The amount of energy wasted by dry flue gases depends on the amount of excess air used for combustion and the final boiler exhaust temperature [1].

  • Flue-gas stack - Wikipedia

    2019-10-1 · A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler

  • Flue Gas Density Calculator - Home • FGKH

    Flue Gas Density Calculator is based on Ideal Gas Law. The flue gas density of a flue gas can be measured using the ideal gas law. It has to be assumed that a real gas behaves as an ideal gas; this assumption is true when gas is at low pressure, so molecular interactions don't affect the system.
