Abstract
A technique for controlling the flow of solid particles including at least a certain minimum amount of magnetizable particles in a static fashion, that is, without moving parts is disclosed herein. This technique which relies on magnetism may be utilized for providing a static on/off valve for solids, a static variable control valve for solids, and other valve related operations. The disclosed technique may also produce a distributor for a fluidized bed of magnetic particles along or in combination with non-magnetic particles, and can also be used as a positively controlled distributor-downcomer for single or staged fluidized beds.
