Stand-alone flue gas recirculation fan

摘要

The formation of pollutants in a hydrocarbon reformer is reduced by use of flue gas recirculation. In typical systems and methods, a hydrocarbon reformer has air intake from an air intake fan where the hydrocarbon reformer produces flue gas exhaust. A portion of the flue gas exhaust is fed into an induced draft fan, wherein a flue gas recirculation ("FGR") fan draws a portion of the flue gas exhaust located downstream of the induced draft fan. The portion of the flue gas is drawn towards an air intake conduit downstream of the air intake fan, which reduces a flame temperature within the hydrocarbon reformer and reduces the formation of NOX.
