NOx Control via IFGR (Induced Flue Gas Recirculation) …

Flue gas recirculation (FGR) acts to reduce NOx formation by reducing peak flames temperatures. In conventional applications, the recirculated flue gas is typically extracted from the boiler outlet duct upstream of the air heater. The flue gas is then returned through a separate duct and hot gas fan to the combustion air duct that feeds the
