ABSTRACT:
A burner for use in furnaces such as in steam cracking. The burner includes a burner tube having a downstream end and an upstream end. A burner tip is mounted on the burner tube adjacent a first opening in the furnace, so that combustion of the fuel takes place downstream of the burner tip. A fuel orifice located adjacent the upstream end of the burner tube is included for introducing fuel into the burner tube. The burner may also include at least one passageway for supplying flue gas from the furnace into a primary air chamber. The burner also has a structure responsive to an inspirating effect created by uncombusted fuel exiting the fuel orifice for drawing flue gas from the furnace through the passageway and the primary air chamber. The burner also includes a plate for centering the fuel orifice with the burner tube, the centering plate being perforated to permit flow therethrough.
