Electrostatic precipitators (ESP) are used to remove particulate matter produced by various processes in the industry. As environmental regulations have increasingly become stringent in recent years, maintaining a high ESP performance is of vital importance in mill operation. This paper discusses the results of experiments conducted at different temperatures to determine how resistivity affects the performance of an ESP. The results found that ESPs perform better at higher temperatures ideally. The results also showed that, contrary to common belief, the resistivity of the material does not affect the charging of the particles directly and only affects the performance of the ESP as a result of the layer that deposits on the collection plates.
