Boiler Combustion | CleanBoiler.org

A valve controls the recirculation rate, based on boiler input. Induced flue gas recirculation utilizes the combustion air fan to recirculate the flue gases back into the flame. A portion of the flue gases are routed by duct work or internally to the combustion air fan, where they are premixed with the combustion air and introduced into the flame through the burner.
