Review: The electrostatic precipitator is one of the most cost-effective means of controlling the particulate emission from large industrial process plants. The most significant changes to them in recent times are the method of energizing the electrode system. Recent high-power fast switching equipment has enabled new high-frequency energization equipment to be introduced, which further improves precipitator performance, which, in turn, reduces the emission levels. Here the author first describes the process physics and the large number of gas and particle characteristics that impact on the design and operation of the precipitator and identifies the requirements of the electrical energization system. He goes on to review the history of the development of precipitator energization up to the present silicon rectifier and thyristor systems, along with the almost parallel development of automatic voltage controllers. Chapters also cover on-line monitoring, and fault-finding and identification.
