Abstract: An enhanced retractable flow discharge extension is configured for use in a coal pulverizer having a classifier system including a feedpipe to deliver from above raw coal to a pulverizing structure and a classifier cone positioned around the feedpipe to collect oversized coal for the pulverizing structure. The enhanced retractable flow discharge extension is configured to deliver oversized coal to the pulverizing structure and has a conical extension portion having an inlet end configured to be contiguous with the classifier cone outlet, a fixed cylindrical portion having an upper end contiguous with an outlet end of the conical extension portion, a movable cylindrical portion having a circumference larger than a circumference of the fixed cylindrical portion, the movable cylindrical portion being movably attached to the fixed cylindrical portion, and a distal portion movably attached to the movable cylindrical portion, the distal portion having a straight portion and a tapered portion.

Abstract: A particulate distributor for pulverized coal flowing to a combustion chamber has an inner cylinder, an outer cylinder concentric with the inner cylinder, an intermediate cylinder concentric with the inner cylinder, a first flow channel defined between the inner cylinder and the intermediate cylinder, the first flow channel having a first cross-sectional flow area, a second flow channel defined between the intermediate cylinder and the outer cylinder, the second flow channel having a second cross-sectional flow area, and an outlet diffuser attached to an outlet side of the particulate distributor, the outlet diffuser having a surface area extending perpendicular to the first flow channel and the second flow channel. The outlet diffuser is configured to reduce the first cross-sectional flow area and the second cross-sectional flow area at the outlet side.

Abstract: A conical cylindrical distributor for particulate coal being fed from a mill/pulverizer to a combustion chamber has concentric, vaned flow channels terminating in dentillated plated extending partially across the flow paths directly at the outlet ends thereof to create turbulence and particle impact to better supply the combustion chamber with a uniform mixture of coal particles.
