An industrial burner assembly (10) characterized by a manifold (56) with a fuel inlet (58) and a longitudinal axis B, and a plurality of elongated burners (12) positioned radially about the longitudinal axis B having fuel ports (42) in communication with the manifold (56) and fuel inlet (58), wherein each elongated burner (12) has an outer mixing tube (14), an inner mixing tube (16) positioned coaxially within the outer mixing tube (14) to form an annular space (18) therebetween in communication with the fuel port (42), the inner mixing tube (16) having an inner surface (16b) forming a passage (40) for air flow through the burner assembly (10), and a plurality of apertures (20) formed in the inner mixing tube (16) to allow introduction of fuel from the annular space (18) into the air flow passage (40) to provide f or efficient mixture of air and fuel in the burner assembly (10) prior to combustion.
