The Benefits of Overfire Air and Flue Gas Recirculation

Overfire air and flue gas recirculation (OAFGR) systems can offer significant benefits to a stoker-fired boiler system, ranging from more efficiency to fewer emissions. Overfire Air and Flue Gas Recirculation Explained. In this configuration, flue gas is taken from downstream of the boiler and combined with combustion air from a draft fan.

Flue Gas Recirculation: History and Uses - EnviroPower

Flue Gas Recirculation (FGR) is the process of taking a portion of the flue gas from a combustion process and recirculating it back through a boiler or burner. When the process is used in internal combustion engines it is commonly referred to as exhaust gas recirculation (EGR). FGR has two primary purposes and one just for gasifiers.
