ABSTRACT:
A distributor for distributing a fluid into the volume of a fluidized bed contained in a vessel comprises a base member in which are mounted upstanding nozzles having outlets for directing the fluid horizontally away from the nozzles into the volume of the bed, the outlets of some nozzles being arranged at a lower level than the outlets from other nozzles so that fluidizable bed material will be fluidized above a contour substantially defined between the outlets of the nozzles. Thus, there will be a "well" or depression in the countour around each nozzle, and the countour will extend to just below the outlet of each nozzle. The contour may be formed by the upper surface of unfluidized fluidizable material (e.g., from the bed) or by the upper surface of non-fluidizable material (e.g. blocks of refractory cement or metal sheeting) which may constitute at least part of the base member. Another fluid may be passed into the volume of the fluidized bed by providing conduits which extend horizontally beneath the countour (e.g. for protection from the fluidized bed) except for one end which extends into the volume of the wells or depressions. The other end is preferably outside the distributor and the conduits are preferably straight and withdrawable from the distributor.
