The report gives results of a detailed study of fabric filter cleaning mechanisms. A highly instrumented, pilot plant system was built to operate as a single- or multiple-bag unit for the investigation of cleaning by mechanical shaking, pulse jet air, and reverse flow air. Four woven bag types (cotton and Dacron) and two felt bag types (wool and Dacron) were evaluated with resuspended fly ash and talc dusts. Analysis of cleaning by both mechanical shaking and pulse jet air indicated that the tensile forces generated by bag acceleration were the main cause of dust removal; aerodynamic re-entrainment played only a minor role. Residual fabric drag, fabric holding capacity, and dust penetration characteristics were predictable, based on such cleaning parameters as shaking frequency, amplitude, pulse jet pressure, and rate of pressure rise.
