On controller integration for electrostatic precipitator

Environment protection is a provocative task in any industrial business and many investments have been made for developing the best techniques in order to minimize pollution, in all its forms. Air dedusting is a main topic in steel industry and one of the solutions used is the electrostatic precipitator (ESP). This device is based on the idea of removing dust particles from a gas flow using electrostatic charge (corona effect). The energy is thus applied only to the particles, not to the gas resulting a very efficient process regarding energy consumption. In this paper a controller is proposed to be integrated in an automation system for controlling an electrostatic precipitator and all its auxiliary equipment.
