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.

Introduction Reduced power utilization has developed into a foremost priority for global industrial sectors over the years. In an estimate from various researchers, it has been predicted that overall energy utilization for different fossil fuels will have a surge of nearly 20% between the year 2015 and 2035 [1, 2]. Hence, to minimize energy consumption and attain better sustainability during filtration process there have been different systems designed worldwide [3–6]. However, there are mainly two types of system which are widely practised for aerosol collection in filtration industries, viz. pulse jet filtration and electrostatic precipitator [7–9]. Meanwhile, both the systems have certain advantages as well as disadvantages when operated individually. Pulse jet system is beneficial for capturing aerosol particles with high efficiency, but it also has to deal with high pressure drop which leads to increase in power consumption
