This study analyzed the particle collection characteristics of an electrostatic precipitator (ESP) based on three performance-influencing parameters: applied voltage, volumetric flow rate, and collection plate type. We employed the flat, tilt, half-tilt, and expand type collection plates. Compared with the flat type, the tilt and half-tilt type exhibited enhanced corona discharge. The half-tilt type exhibited a 9 % higher collection efficiency than the flat type at φ = 12 kV and Q = 0.15 m³/s. Additionally, the expand type exhibited the same electric-field trend as the flat type; however, it developed a separation region in the flow-velocity distribution. Consequently, its efficiency was higher under φ = 9 kV than that at φ = 12 kV because the separation region prevented the particles from attaching to the collection plates. Using the results, we developed an prediction model with a single hidden layer comprising 18 neurons. The predictions agreed well with the numerical simulation results, exhibiting errors within ±10 %.
