ABSTRACT:
A chamber for the treatment of particulate matter in a fluidized bed, e.g. at elevated temperatures, comprises an apertured bottom for the admission of carrier gas into the overlying space. The latter is divided by upstanding partitions into at least one medial compartment and at least two additional compartments adjoining the at least one medial compartment at the opposite sides of the latter. The apparatus further comprises a duct of substantially triangular cross-section with a horizontal base and an upwardly sloping side walls located in the at least one medial compartment, with the side walls of the duct extending in directions parallel to the partitions, and the base of the duct being imperforate and resting on the wall of the chamber and preventing the entry of the carrier gas into the at least one medial compartment from below; and a nozzle arrangement in each of the upwardly sloping side walls of the duct. The partitions may be formed from louvres generally parallel to the axes of nozzles through which a flow of ancillary gas is directed from a duct in a given compartment into two adjoining compartments; particles descending from above into that given compartment are thus entrained by the ancillary gas into the adjoining compartments.
