Abstract
A bed plate for a fluidized bed defines a plurality of substantially uniformly distributed openings therein for allowing fluidizing gas to flow upwardly through the plate. The openings are divided into pairs and directed and shaped so that the gas flows through the openings of each pair are directed in converging relationship, thereby to create a resultant flow component which is directed towards a discharging position of the fluidized bed. The desired resultant flow component may be obtained by properly selecting the direction and shape of the openings in each pair of openings. The gas flows through the openings in each pair may, for example, define an angle of 60.degree. to 120.degree. therebetween.
