• Laboratory-scale vertical wet ESP was operated in air–water droplets flow.
• The model is in good accuracy with measurements while considering vapor content.
• Corona current decreases for high flow rates at the same applied voltage.
• Effects of geometric parameters and electric indexes on ESP efficiency are studied.
• There is an optimum wire-to-flow inlet spacing that provides maximum efficiency.
A single-stage, single-wire vertical wet electrostatic precipitator was designed and operated in air–water droplets flow to investigate its performance. The efficiency was compared with a glass micro fiber filter and proposed semi-empirical efficiency model, which was in good accuracy while considering the vapor content. Effects of geometric parameters on efficiency under different charge conditions were discussed. Due to evaporation mechanism, the corona current decreases for high flow rates at the same applied voltage. Findings indicated while developing flow is created inside the ESP, there exists an optimum wire-to-flow inlet spacing that provides maximum droplet collection efficiency.
