x

emissions from process heaters, boilers, and other heating systems having flue gases present therein. The inventive burner and method preferably involve the single stage combustion of fuel gas which is ejected outside of a burner wall in free jet flow such that at least a portion of the flue gas is entrained in the fuel gas as it travels to a combustion zone at the forward end of the burner wall. Air or other oxygen-containing gas is preferably delivered to the combustion zone via an interior passageway. The inventive burner preferably comprises a plurality of ejectors positioned outside of the burner wall and preferably also comprises one or more exterior impact structures positioned to assist in further mixing the flue gas with the fuel.
