Recent tests at The University of Tennessee in Knoxville (UT) have demonstrated improved fluidization performance in a mockup of the Oak Ridge Y-12 Plant fluidized bed with a modified gas distributor. Combining the modified distributor with the recently developed fluidization intensity module is expected to result in substantial operational improvements for the fluidized beds in Building 9212 at Y-12. Important additional benefits coming from the improved operation of the Y-12 fluidized beds will be a reduction in the consumption of reactant gases, a reduction in scrubber waste production, and a reduced need for manual cleaning of the particulate removal system. UT tests have also demonstrated that the tapered wall design traditionally used for the Y-12 fluidized beds does not provide a sufficient improvement in fluidization quality to justify the continued use of this design in place of a more conventional straight-wall configuration. The straight-wall design for replacement beds is expected to result in substantial equipment cost savings. Other operating scenarios that could potentially be used to reduce reactant gas consumption and scrubber waste production have also been considered. These scenarios are documented here for future reference.
