Flue Gas Recirculation definition

Flue Gas Recirculation or “FGR” shall mean extraction of a portion of the flue gas downstream of the furnace exit and reintroducing it into the combustion air stream to reduce NOx emissions.
Sample 1Sample 2Sample 3
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.
