  • 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

  • Deposit Build-up and Corrosion in a Copper Flash Smelting

    Nov 14, 2016 · The process gases pass through the settler and the up-take shaft and enter the heat recovery boiler. In the radiation section, the process gas cools down to 600–700 °C and further in the convection section to 350 °C. One characteristic of the smelt process is the presence of a large amount of flue dust particles in the off-gas.Learn More

  • Method of hot scrubbing flue gases, in particular for an

    The recovery boiler 3 is in two portions 3a and 3b in this example, the flue gases passing through both portions. A "high-temperature filter" element 4 is interposed between the two portions 3a and 3b of the recovery boiler, on the path of the flue gases. The filter element 4 serves to perform hot scrubbing on the flue gases.Learn More

  • Calculator: Flue Gas Analysis - Thermodyne Boilers

    Flue Gas Analysis Calculations. Flue gases are formed on combustion of air with fuel in the presence of heat.
