摘要

For several years the Department of Energy (DOE) has supported the development of devices for particulate cleanup of the effluent gas streams from pressurized, fluidized-bed combustion (PFBC). These devices are: acoustic agglomerator, under development at the Pennsylvania State University; ceramic baghouse filter, being developed by Acurex Corporation; ceramic cross-flow filter, under development at Westinghouse Electric Company; dry plate scrubber, from Air Pollution Technology, Inc.; ducon granular bed filter, being developed under contract to Westinghouse; electrostatically-enhanced granular bed filter, under development at General Electric Co.; electrostatic precipitator, at Research Cottrell and Denver Research Institute; electrocyclone, under development at General Electric; magnetically-stabilized bed filter, from Exxon Research and Development Company; and screenless granular bed filter, under development by Combustion Power Company. In each device, cleaning of the gas streams takes place at high-temperature and high-pressure (HTHP) conditions. The present stage of development for each device ranges from bench-scale to sub-pilot scale. Although none of these hot gas cleanup (HGCU) devices is ready for PFBC commercialization, sufficient data do exist to estimate the potential for applying these HGCU technologies to coal gasification gas stream cleanup also. 173 references, 46 figures, 47 tables.
