ABSTRACT:
A pulverized fuel distribution cone for use in a pulverized fuel burner having a tubular burner pipe with flanged and furnace ends and an elbow connector having a flanged end for connection of the elbow to the flanged end of the burner pipe. The distribution cone includes an open base section and an open outlet end portion extending into the burner pipe. A planar flange extending outwardly from the base section of the cone is retained between the flanged ends of the elbow connector and pipe. The flow cone preferably is positioned in the pipe at a distance from the furnace end of the burner of at least four times a diameter of the pipe. An angle between the wall of the cone and its base in the range of from 75.degree. to 85.degree. results in a flow deflection of between 5 and 15 degrees, respectively. The length of the cone in the flow path preferably is in a range from four to fourteen inches.
