The report describes laboratory and pilot scale testing of bag filter fabrics. Filtration performance data and mathematical modeling parameters are given for four Polish fabrics tested with cement dust, coal dust, flyash, and talc. Conclusions include: (1) The process of clean air flow, as well as the dust filtration process, are stochastic processes of the normal type. (2) For filtration Type I (laboratory scale), dust collection efficiency is an exponential function depending on air-to-cloth ration, dust covering, and type of filtration structure. (3) For filtration Type I, resistance increases parabolically with time or dust covering. Outlet concentration as a function of dust covering is also parabolic. Structurally, the fabrics are heterogeneous anistropic media. (4) Free area is presently the best structural parameter for characterizing structure of staple fiber fabrics. (5) Electrostatic properties of dusts depend on their history; charge decays with time. Dust cake formation can be influenced by specific electrostatic properties of the fabric and dust.
