ABSTRACT
Although electrostatic precipitators have been employed almost for a century to remove particulates, fumes, and mists from a wide range of industrial processes, the main approach for assessing the size and design of a new plant has been based on measurements from units operating under similar conditions. Recent developments using computerized ˜uid dynamics approaches have enabled the physics to be theoretically studied in greater detail, which leads to an improved understanding of precipitation. In this chapter, the precipitator operation is reviewed from theoretical and practical aspects and some of the gas and particulate characteristics, which have to be considered when designing a precipitator for a speci”c duty,
