The report gives results of an extensive testing program performed on a fabric filter baghouse operating on a small coal-fired utility boiler. Total mass loadings were obtained by sampling upstream and downstream using Method 5 techniques; particulate size distributions were obtained with instack impactors. A condensation nuclei counter/diffusion denuder system was also used for submicrometer sizing analysis, but the instrumentation was found to be difficult to work with and very sensitive to the static pressure of the sample stream. The results of 22 tests indicated a mean mass efficiency of 99.84 percent. Eleven tests were run at normal baghouse operating conditions and eleven were run at abnormal operating conditions. Statistical analyses show no significant influence of the abnormal operating conditions on particulate penetration.
