ABSTRACT:
A bottom for a fluidized bed conveyor is composed of a plurality of members provided with openings and located in contact with each other so that their points of contact are gas impermeable at least during operation of a fluidized bed. The openings may be formed as circumferentially closed holes and/or as laterally open recesses. The members may laterally abut against each other, or may be provided with interengaging lateral projections. The members may be located so that at cold temperatures small intermediate spaces remain therebetween, which spaces are closed during operation as a result of thermal expansion of the members under the action of high working temperatures. Bracing element or elements may be provided which urge the members toward one another.
