The objective for this quarter was to test the advanced hybrid particulate collector (AHPC) in real flue gas conditions. The initial tests were performed on the particulate test combustor (PTC) firing Absoloka subbituminous using two types of bags: PTFE and graphite-impregnated PTFE. Both bag types were evaluated in the on-line and off-line cleaning modes. Findings showed only a small difference in performance between the PTFE and graphite-impregnated PTFE. In the on-line cleaning mode, both the PTFE and graphite-impregnated PTFE bags maintained pressure drop across the bags of between 8.0 and 6.0 in. W.C. In the off-line mode, the pressure drop across both bag types ranged from 8.0 to 5.5 in. W.C. Dust-loading efficiencies averaged 99.986% over all the tests. The objective of the project is to develop a highly reliable AHPC that can provide > 99.99% particulate collection efficiency for all particle sizes from 0.01 to 50 {micro}m, is applicable for use with all US coals, and is cost-comparative with existing technologies
