Westinghouse Standleg Moving Granular Bed Filter (SMGBF) development for hot gas cleanup and other applications
- Westinghouse Electric Corp., Pittsburgh, PA (United States). Science and Technology Center
A novel Standleg Moving Granular Bed Filter (SMGBF), having inherent advantages over the current state-of-the-art moving granular bed filter technology, has been developed at Westinghouse for high-temperature and high-pressure applications at operating conditions of PFBC, IGCC, and DCFT. The technology is potentially competitive with ceramic barrier filters and its development program is complementary to the existing Westinghouse development program in ceramic barrier filters. The technology details and the experimental results from large-scale test facilities are reported. Its potential applications in other areas are also discussed. Westinghouse`s SMGBF technology is a simple, compact, and reliable design. The SMGBF, illustrated in a figure, makes use of a short straight standleg to allow intimate contact between the flowing gas stream and the moving granular bed. Gas is then allowed to flow out over the surface of the bed formed naturally below the standleg. Simultaneously, the particulates in the gas stream are trapped and retained by the moving granular bed. With a standleg height of 0.91m (the design for the standard module), the particulate collection efficiency has been found experimentally to be up to more than 99.9%. The simple design and known scaleup criteria for a moving bed in a vertical standleg minimize uncertainty about scaleup to larger sizes and elevated temperatures and pressures.
