1.4 Natural Gas Combustion - US EPA

Jun 19, 2019 · 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.

Low NOx Burner: An Introduction - RUICHANG

A flue gas recirculation burner providing reduced No x emissions uses a cylindrical tangential mixer to separately receive combustion air and flue gas through axial inlets. The mixed air and gas pass through a vaned diffuser which continues the tangential flow pattern, and thereafter fuel is introduced tangentially and combustion occurs.

Fuel induced recirculation is a control technology for natural-gas-fired boilers. FIR involves the recirculation of a portion of the boiler flue gas and mixing it with the gas fuel at some point upstream of the burner. The primary difference between FIR and FGR is that in FIR the flue gas is mixed with the fuel stream, whereas in FGR the flue
