Description 19-26
Present study embodies filtration characterization of two nonwoven needle-felt polyester filter materials, viz. PTFE
coated and without coated media. The materials have been assessed using flyash aerosol under varying time intervals
(6, 9 and 12 min) at different inlet dust densities (50, 90 and 150 g/m3). The flyash particles are charged prior to their
deposition over the filter media using a three phase parallel plate box pre-charger at two different levels of pre-charge, viz.
4 kV and 8 kV along with 0 kV. Results reveal that the filtration performance for PTFE coated material is better under all
conditions. However, an enhanced filtration performance in terms of particle emission and pressure drop is noted at
increased pre-charge level and higher cyclic interval. It may also be noted that the level of improvement in filtration
behavior for both the materials has been better at initial level of pre-charge from 0 kV to 4 kV. However, the cumulative
behavior of all the factors is also found significant.
