The paper describes the performance of the Acurex ceramic bag filter operating at temperatures up to 880C and pressures up to 930 kPa on particulate-laden flue gas from a pressurized fluidized-bed coal combustion (PFBC) unit on a slipstream of gas taken after the second stage cyclone. Particle concentrations before and behind the filter, filter face velocities during the tests, and the pressure drop across the filter before the start of the cleaning cycle and immediately after the cleaning cycle were described. Three western and midwestern coals were used. Tests, ranging from 4.5 to 17 hours, in general showed that the filter could achieve high efficiency collection and was able to stabilize pressure drop with the cleaning cycle. This significant achievement in the high-temperature, high-pressure environment indicates that the ceramic fiber filter concept should receive further study to investigate longer term performance and scale-up for potential application as the final cleanup device for PFBC.
