• • Wire mesh pore size of 1 mm yields the highest dust removal efficiency; smaller apertures enhance capture of fine particulates, critical for meeting stringent PM2.5 emission limits.
• • Increasing the number of mesh layers (up to 3) effectively improves efficiency at discharge voltages of 13–17 kV, providing an operational lever for optimizing performance under varying load conditions.
• • Coating the wire mesh with polyethylene or polyamide filtration materials further enhances efficiency, with both materials showing comparable performance, offering flexible material selection based on cost and durability.
• • Magnetic field enhancement significantly improves removal of high-resistivity dusts (e.g., cement ash) by suppressing back corona, which is a common failure mode in conventional ESPs, thereby extending applicability to challenging dust types.
