Characterization and failure analysis of ceramic filters utilized for emission control during coal gasification. Quarterly report, July 1--September 30, 1997

The research activities performed at PV A and M University in the third quarter of 1997 are summarized within. PV A and MU had performed mechanical and back pulse testing to characterize the performance of the filter and is using the process of elimination to perform the failure analysis for filters. The mechanical testing performed on the filters are categorized as follows: the acceleration testing; the vibration testing; the air jet impulse testing; and the impact testing. The major work completed in the third quarter, 1997 for filter back pulse cleaning testing included the following items: (1) the completion of the test system; (2) the procurement of particulate sample; (3) the development of a data acquisition system; (4) the filtration pressure field monitoring with the use of micro-fast pressure sensor assembly; (5) the design of a back pulse system; (6) completed a back pulse cleaning test plan; and (7) started performing parametric testing on particulate removal. The bulk of this report consists of a user`s manual for the automatic testing on instrumentation interfacing
