ABSTRACT:
The constriction plate of a fluidized bed incinerator is divided into a plurality of smaller perforated plate elements which are attached to an underlying frame structure with a mutual spacing corresponding to the heat expansion which the elements are subjected to during operation of the incinerator. The plate elements have bent rims so as to rest upon the support along sharp edges and are resiliently attached to the support. Attachment of the plate elements is effected by attachment means threaded through holes in the elements and embracing the bent area of the plate elements in the upper area thereof, the attachment means at their lower ends having a threaded area for screw connection to a resilient attachment piece. The attachment means may be arranged in pairs, each pair at their lower ends being attached to a common resilient attachment piece.
