ABSTRACT:
A bed support, and a fluidized bed reactor incorporating the bed support, the bed support including a conical-shaped support with downwardly converging surfaces terminating in a conduit for removing tramp material and/or agglomerated material from the reactor. The downwardly converging surfaces have main air source nozzles for directing pressurized air parallel to and downwardly along the downwardly converging surfaces toward the conduit. In a first embodiment, the conduit has downwardly diverging walls. In a second embodiment, the conical-shaped support further includes an inverted cone positioned over the conduit, the inverted cone having central air source nozzles and slots in the lower portion of the cone. In a third embodiment, the conical-shaped support further includes a bar grate having central air source nozzles positioned within the conduit. The method of operating the fluidized bed reactor includes directing pressurized air parallel to and downwardly along the downwardly converging surfaces toward the conduit for fluidizing the bed and for preventing tramp material and/or agglomerated material from collecting on the downwardly converging surfaces, and removing tramp material and/or agglomerated material from the reactor through the conduit.
