Textbook in PDF format The reader receives information on electrical gas cleaning systems as they are operated in power plants, steel works, cement works, chemical plants, CHP plants and biomass power plants. Electrostatic precipitators clean gases, especially exhaust gases, from dust and aerosols down to the smallest particle sizes. With reference to practice, the book explains the physical, constructive and electrotechnical basics. It also describes the requirements for the design and operation of these systems. The current edition deals in particular with the physics of negative and positive corona and the extended application possibilities that arise from the targeted use of positive corona. A number of references show ways to calculate and cost-effectively build a new electrostatic precipitator - or to upgrade or convert an existing one for lower clean gas values
