This patent describes an improved burner assembly for a furnace having a combustion zone in which internally recirculating flue gas is crated by a combustion flame therein, the furnace having a wall portion and a furnace floor with an inlet port for intake of a combustion supporting fluid. It comprises: burner means for combusting a fuel with the combustion supporting fluid to produce the combustion flame; means for directing internally recirculating flue gas in the furnace into reaction contact with the combustion flame; a barrier disposed in proximity to the furnace floor portion and cooperating therewith to form a flue gas tunnel.
