Second-generation pressurized fluidized bed combustion (PFBC) plants promise higher efficiency with lower costs of electricity and stack emissions. A 45 percent efficiency and a cost of electricity approximately 20 percent lower than that of a pulverized-coal-fired plant with stack gas scrubbing are being projected. Foster Wheeler Development Corporation has constructed and is operating a second-generation PFBC pilot plant at the Foster Wheeler research facility (the John Blizard Research Center) in Livingston, New Jersey. Testing is under way to support the development of this new type of plant and validate commercial plant performance predictions. Carbonization tests have been conducted with several coals over a 10 to 14 atm pressure range both with and without steam injection. Ceramic barrier filters are key components of second-generation PFBC plants. This paper describes the, crass flow barrier filter test unit designed to clean the fuel gas generated by the pilot plant carbonizer. The design basis and special features of the filter system are outlined. Test experience with the carbonizer-generated fuel gas is reviewed and assessed with respect to operability, reliability, and scaleup. Test experience on the carbonizer fuel gas is compared with performance observed in other test applications.
