This report is an addendum to an earlier published EPRI contract report (EPRI CS-1846) on the evaluation of Ceramic Fiber Filters for Pressurized Fluidized-Bed Combustion (PFBC), Hot Gas Cleanup. The work presented is the result of a second test series (Test Phase II) that was conducted on the five-bag, felted-ceramic filter unit in a simulated PFBC environment. The filter was operated at higher than conventional filter air-to-cloth ratios, 10 ft/min (3 m/min), and was designed for off-line cleaning by a pulse-jet method. Results of tests are reported that suggest a decreasing performance level for the filter with continued operation and ineffective cleaning with the pulse-jet method. These results are partially attributable to insufficient capacity in the pulse-jet air supply system. Test data and results are described and discussed that reflect on both the filter bag test unit operation and the nature and evaluation of the problems encountered with the pulse-jet cleaning.
