  • Boiler Combustion - CleanBoiler.org

    Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature and reduce NOx formation.Get Price

  • 1.1 Bituminous And Subbituminous Coal Combustion

    combustion. In pulverized coal systems, combustion is almost complete; thus, the emitted PM is primarily composed of inorganic ash residues. Coal ash may either settle out in the boiler (bottom ash) or entrained in the flue gas (fly ash). The distribution of ash between the bottom ash and fly ash fractions directly affects the PM emission rateGet Price

  • 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) …Get Price

  • Understanding Oxygen Measurement in Flue Gas Streams

    Jun 29, 2021 · When combustion is more difficult, the excess amount may need to be higher. For example, a pulverized-coal-fired boiler will run around 3 to 4% excess O 2, and a municipal solid waste boiler will be even higher, perhaps 5 to 7% excess O 2. Most gas- and oil-fired installations will be well below 3% excess O 2. Controlling combustionGet Price
