Abstract
A combustion apparatus and process for improved flue gas recirculation wherein the recirculation line penetrates into an exhaust duct, such as the exhaust stack for capturing and directing a portion of said flue gas through the recirculation line which is connected to an air fan inlet which provides induction of the flue gas into the combustion unit. The portion of the recirculation line that extends into the exhaust stack is preferably aerodynamically configured to capture a portion of a flue gas stream without detrimental impedance of the gas flow.
