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.

An apparatus for minimizing fuel roping in a pulverized fuel burner, comprising: a distribution half-cone formed from ceramic material of substantial thickness and formed to have an inlet of a first diameter and an outlet of a second diameter smaller than said first diameter, said inlet being formed

An apparatus for minimizing fuel roping in a pulverized fuel burner, comprising: a distribution half-cone formed from ceramic material of substantial thickness and formed to have an inlet of a first diameter and an outlet of a second diameter smaller than said first diameter, said inlet being formed as a sharp edge nozzle formed at an angle within a range of approximately 15°to 45°from an outside edge of said inlet along the substantial thickness to an inside diameter of said distribution half-cone to form a sharp edge slope at the nozzle inlet to minimize pressure drop across said distribution half-cone to pulverized fuel flow therethrough; and mounting means for mounting said distribution half-cone within a burner nozzle of the pulverized fuel burner so as to provide a gap between said burner nozzle and said distribution half-cone for splitting a flow of pulverized fuel therethrough into a first portion flowing through said gap and a second portion flowing past a side of said distribution half-cone opposite said gap when said distribution half-cone is installed within said burner nozzle. A burner for pulverized fuel, comprising: a fuel inlet, an elbow section connected to said fuel inlet, and an elongated, substantially circular burner nozzle connected to said elbow section for exhausting a flow of pulverized fuel for combustion; and a distribution half-cone mounted within said burner nozzle at the outlet of said elbow section so as to provide a gap within a range of approximately ¼-⅛inch between said burner nozzle and said distribution half-cone for splitting the flow of pulverized fuel into a first portion flowing through said gap and a second portion flowing past a side of said distribution half-cone opposite said gap.
