  • Exhaust Gas Recirculation - an overview | ScienceDirect Topics

    In conventional FGR applications, 20 to 30 percent of the flue gas is extracted from the boiler outlet duct upstream of the air heater (at ≈570–750 F) and is mixed with the combustion air. This process reduces thermal NO x formation without any significant effect on fuel NO x .Get Price

  • How is flue gas recirculation used to reduce NOx? – …

    What does flue gas recirculation do to a boiler? This is known as flue gas recirculation (FGR). Although it might be considered that reheating the hot flue gases may exacerbate the production of NOx, the relatively cool (compared with the combustion chamber) inert gas lowers the temperature of the flame, so reducing the production of NOx.Get Price
