Abstract:
Energy consumption is a vital aspect for any
industry considering the cost-effective aspect. The current
study embodies the power consumption during filtration of
conductive filters at different dust pre-charging levels on
laboratory-based pulse jet tubular set up assisted with precharger. Three types of polyester conductive non-woven
filter materials, viz. PTFE-coated media, stainless steel
fibre blended with PET media and stainless steel scrim
media, have been characterized at three different charge
levels, viz. 4 kV, 8 kV, 12 kV, and without charge. The
outcome revealed that there has been a significant drop in
power consumption with the rise in pre-charge level.
Energy utilization results have further been compared with
full-scale bag house condition by calculating the energy
consumed for 50 bags. The results showed that among all
the materials taken for investigation the performance of
PTFE-coated media is the best and role of material is most
significant towards the energy consumption by the filtration
system. Overall energy consumption decreases with rise in
pre-charging level. It is observed that percentage contribution of energy utilized for fan has been much higher for
full-scale bag house as compared to tubular-based set-up.
However, in case of energy consumed by the compressor,
the difference in percentage contribution is relatively less
and for energy utilized due to charge, not much variation in
contribution can be noted.
