Electrode Shape and Collector Plate Spacing Effects on ESP Performance
ElectroStatic Precipitator (ESP) suppliers are today conducted to reduce installation cost and due to world-wide environmental emission requirements also to improve performance. Two important and critical factors when designing high performance ESPs are discharge electrode design and collector plate spacing. Simulation and experimental results obtained in a pilot precipitator are used to investigate fundamental effects of the electrode shape for different collector plate spacing (Results-Part 1-Simulations) and to study more aggressive electrodes for 300 mm and 500 mm plate spacing (Results-Part 2-Experimental study). The ESP simulation model demonstrates, for different electrode shapes and collector plate spacing, basic characteristics of current-voltage-characteristics, current density at collecting plate, efficiency, turbulence level, strength of ionic wind, and effect of dust load. The experimental study focuses on electrode evaluation based on electrode shape and emitter orientation. An intensive study of several different electrode shapes has been carried out. ESP efficiency for wide spacing between collector plates is discussed in view of electrode shape and emitter orientation.
