Electrostatic Precipitator is the device used for controlling air pollution. This is used for cleaning of boiler process gases. Process gases contain suspended dust particles. These dust particles are collected on collecting electrodes. The effectiveness of Electrostatic Precipitators is affected by various factors. Periodic cleaning of collecting system plays a major role. Dust gets deposited on collecting electrodes and dislodged by means of vibrations of collecting electrodes. For huge volume of process gas the size of Electrostatic Precipitator will also be large. Since space is major constraints the ultimate solution will to go vertically i.e. increase the height and accordingly the collection area. Since the height is increased old methods of rapping will be ineffective and hence the new methods introduced to increase the vibration. Time is another major constraint for checking of such continuous improvements. So simulation and further physical measurement is more practical method. This paper presents FEA concept of modelling and analysis of collecting electrodes of an Electrostatic Precipitator by Implicit Transient Dynamic Analysis. Experimental testing is done for validation. The results of FEA concept and physical measurements are discussed.
