The present study aims at comparing the pressure drop behavior of three different needle-punched polyester conductive materials, viz. PTFE coated media, stainless steel fibre blended with PET media and stainless steel fibre scrim media. This comparison is done on a laboratory-based electrostatically assisted pulse-jet flat media test rig with the pilot filter unit, which is closer to the industrial set-up. The materials are investigated using fly ash aerosol, pre-charged at three different levels of charge, viz. 4 kV, 8 kV and 12 kV. The interpretations reveal that the flat media test rig is observed to exhibit lower residual pressure drop for all the investigated materials.

Abstract


The present study aims at comparing the pressure drop behavior of three different needle-punched polyester conductive materials, viz. PTFE coated media, stainless steel fibre blended with PET media and stainless steel fibre scrim media. This comparison is done on a laboratory-based electrostatically assisted pulse-jet flat media test rig with the pilot filter unit, which is closer to the industrial set-up. The materials are investigated using fly ash aerosol, pre-charged at three different levels of charge, viz. 4 kV, 8 kV and 12 kV. The interpretations reveal that the flat media test rig is observed to exhibit lower residual pressure drop for all the investigated materials.
