Abstract
A solid particle flow distribution controller includes an extension skirt configured to be mounted to a discharge skirt at a division between an upstream solid particle conveyance pipe and a plurality of downstream pipes. The extension skirt includes a plurality of circumferential segments. Each segment is movably mounted to the discharge skirt for movement in an upstream and downstream direction with respect to the discharge skirt. The segments of the extension skirt are configured and adapted for motion in the upstream and downstream direction independent of one another to extend upstream of the discharge skirt as needed to improve solid particle distribution among the downstream pipes.
