The report gives results of research aimed at developing filter media performance data under simulated pressurized fluidized-bed combustion conditions for one ceramic filter media candidate. A low-solidity fiber bed, using Saffil alumina ceramic filters was selected. Dust feeding was tested at a nominal 800 C and 10 atm pressure, using reentrained fly ash which had been collected at the EPA/Exxon Miniplant. Tests were performed at three filter media face velocities: 2.5, 4.8, and 9.0 cm/sec. Each test was 200 hours long. Pressure drop and collection efficiency were determined as functions of time and filter face velocity. Off-line cleaning by reverse pulse was effective in maintaining low pressure drop (<1.25 kPa) after a cleaning cycle. Collection efficiency was high (>99.9 percent) and was maintained over the 200 hour test. Collection efficiency was also substantially independent of face velocity over the range tested. Outlet concentration was less than the most stringent requirements proposed for turbine applications (generally <1 mg/cu Nm). Outlet concentration showed a trend toward lower values at higher filtration velocity. Mechanical durability was indicated in that none of the test filters appeared to have been damaged by the 200-hour tests with cleaning at 10-minute intervals.
