Fluidized bed reactor utilizing a plate support and method of operating the reactor

摘要

A bed support, and a fluidizing bed reactor incorporating the bed support, the bed support including a horizontal support surface with a centrally disposed conduit for removing tramp material and/or agglomerated material from the reactor. The horizontal support surface has fluidizing air source jet nozzles for directing pressurized air toward the area above the conduit. In a first embodiment, the conduit has downwardly diverging walls. In a second embodiment, the horizontal support surface further includes a bar grate having central fluidizing air source jet nozzles positioned within the conduit. The method of operating the fluidized bed reactor includes directing pressurized air at an angle to the horizontal support surface both for fluidizing the bed and for moving the tramp material and/or agglomerated material toward the conduit for removal from the reactor through the conduit.
