Abstract
A nozzle for a recuperative radiant tube burner system is constructed to provide uniform combustion along the length of the inner tube. The nozzle includes combustion air ports disposed at compound angles and having different axial components to provide staged mixing of air and fuel. The staged mixing produces a combustible mixture along the length of the tube to produce a more uniform flame. The nozzle further has an outer wall disposed normal to the combustion air ports to improve air flow through the ports. A fuel outlet tube has relief ports for continuing fuel flow in the event that a main orifice is plugged, which may result from air pressure fluctuations in the burner system.
