Abstract
A distribution half-cone for a granular or pulverized fuel, typically coal, burner is mounted within a burner nozzle thereof proximate to a burner elbow of the burner to provide a space or gap between an inner wall of the burner nozzle and the outer surface of the distribution half-cone of approximately 3/16 inch to prevent fuel roping and to minimize the pressure drop in the burner. The inlet of the distribution half-cone is formed as a sharp edge nozzle to minimize pressure drop in the burner.
