A series of tests was conducted to evaluate the performance of ceramic candle filters at elevated temperatures and pressures using the hot product of a combustion stream, laden with resuspended particulate, from a bench-scale pressurized entrained combustor. Four tests using 1 m length, grade 50/10, silicon carbide candle filters from Industrial Filter and Pump (IF P) were evaluated at three face velocities with two cleaning techniques. Tests 1, 2, and 3 were operated at nominally 1.550{degree}F, 8.5 atm, with particulate loadings of 775 to 840-ppMw. Test 4 was operated at 1,370{degree}F, 9.9 atm, with a 838-ppMw particulate loading. Gas flow rates for Tests 1, 2, 3, and 4 were nominally 43, 68, 68, and 27 actual cubic feet per minute (acfm), respectively. During steady operating conditions, the specific resistance coefficient (K{sub 2}) for each of the four tests was within the range of 16 to 22 in. H{sub 2}O{center dot}ft{center dot}min/lb. Candle filter permeability varied with face velocity and cleaning technique used. Permeability decreased with increasing face velocity when temperature and pressure were held constant, and increased with off-line versus on-line cleaning when face velocity was held constant. 6 refs., 32 figs., 10 tabs.
