The report describes a computerized mathematical model that can be used to estimate the collection efficiency of electrostatic precipitators (ESPs) of different designs, operating under various conditions. (ESPs are widely used to control emissions of fly ash and other dusts from industrial sources.) Mathematical expressions based on theory are used to calculate electric fields and dust particle charging rates. Empirical corrections are made for non-ideal effects such as a non-uniform gas velocity distribution. The model is expected to aid in improving ESP design and in selecting optimum ESP operating conditions.
