ABSTRACT:
Semi-insulating granular bed material in a spout inlet region of a spouted bed vessel between a draft tube and a portion of the vessel base section adjacent a fluid inlet is aligned along the force lines of an imposed localized electric field to thereby afford improved control over spout inlet conditions which affect processes carried out in the spouted bed device.
