Abstract
A diffuser assembly is configured to support a fluidizable medium on a fluidized bed. The diffuser assembly includes a diffuser board which is permeable to air and impermeable to the fluidizable medium, and a metal plate coupled to the diffuser board. The metal plate is formed to include a plurality of apertures therein to permit air to pass through the metal plate. The metal plate has an outer perimeter edge. The plurality of apertures are spaced inwardly from the outer perimeter edge of the metal plate by a predetermined distance to define a solid border configured to block air flow through the metal plate adjacent the outer perimeter edge.
