Modelling and Simulating the Effect of the Different Geometric Parameters on Voltage-Current Characteristics for Wire-Plate Electrostatic Precipitator with Different Collector Configurations

Evaluating Performance Indices of Electrostatic Precipitators

“…Other parameters, including electrode designs and their respective layout, can also affect the corona discharge. Verifying numerical ESP models is another common use case for I-V characteristics through direct comparison at different geometries, as shown in Figure 5 both numerically [11] and experimentally [9]. It can also be seen that varying the number of discharge electrodes has a pronounced effect on I-V characteristics.…”

“…Another method of assessing the ESP performance is comparing the effect of changing geometric parameters on the resulting corona current-voltage (I-V) characteristics of an ESP [7][8][9][10][11][12][13]. This method involves measuring the value of the corona discharge at each voltage value, where higher corona current values imply more deposition.…”

“…Changing the collecting electrode geometry can alter the performance of an ESP significantly. This is because bending the collecting plate creates a region with a highintensity electric field near the collecting plate [4,11,27,54]. Another benefit is that changing the design of the collection electrode improves the capturing process of the precipitated particles [4,27] in the case of C-and W-type collection plates, which is especially prevalent for two-stage ESPs.…”

“…Unlike the effect that the discharge wire spacing has on collection efficiency, the effect of plate-to plate spacing is much more prominent [18,19], making it one of the more important criteria when evaluating the performance of an ESP. Generally, the collection efficiency is higher for narrower channel widths (less spacing) between subsequent plates (assuming constant current density) [5,11,16,18]. The effect is especially apparent in wireplate type and transverse plate ESPs (Figures 1 and 2, respectively).…”
