Flue Gas Recirculation or “FGR” means extracting a portion of the flue gas and returning it to the steam generating unit firebox. FGR reduces the oxygen concentration in the combustion air by using oxygen depleted flue gas as a portion of the combustion air and thereby reduces the combustion temperature, resulting in lower NOx emissions.
