Abstract

Electrostatic precipitators (ESPs) have undergone tremendous changes and have been modernized over the last few decades. Recently, several innovative methods of construction have arrived and the implementation has resulted in a fine response in the cleaning action leading to in reach to the goals of the organization. Through this, few modifications are made in the design of an ESP and aimed to increase the cleaning efficiency in the environment, majorly for several particles in the ranges of micro to sub micrometric sizes. Nowadays, the country is spending to implement many projects for the prevention of atmospheric particulate pollution from electricity generating plants.  Though many installations have existed in the iron and steel, cement, nonferrous, chemical processing and incineration industries, the air pollution control requirements becoming increasingly more stringent. It is necessary to have a close monitor and accurate control system to focus on the key parameters of an ESP control system. The efficient operation of an electrostatic precipitator (ESP) in practice depends upon many variables, such as charging method, particle size, gas flow, temperature, dust resistivity, etc. The efficient functioning of an ESP normally means minimizing power consumption and maximizing dust collection. Several control strategies can be adapted to meet this broad requirement. Adding electrical forces to traditional filters has also resulted in an increase in their collection efficiency for removing dust particles. This paper describes the principle of operation of an ESP and the development of an ESP in the latest era. A simple and fine working model of an ESP is demonstrated.
