Abstract

Fluidized bed apparatus, comprising a fluidized bed vessel in which a substantially horizontal rotor disc is arranged above a perforated bottom or above an air chamber for rotary movement about an at least approximately vertical axis and for adjustment along said axis. The fluidized bed vessel is tapered upwardly, one portion inwardly and one outwardly to enhance the flow therein and the rotor disc forms a flat cone and the disc may have a central cone with the rotor disc covering at least the central part of the perforated bottom.
