Abstract:
There is a concern about the effect of gas temperature on the entrance of electrostatic precipitators (ESP) in relation to the efficiency of particulate collection. Thus, a review was carried out in the bibliography related to the subject, evaluating how the temperature would interfere in the efficiency of the ESP. It was observed that several variables would influence the efficiency of this equipment, especially some parameters, including electrical (current and voltage), those related to the matter (particle size and electrical resistivity) and process (gas velocity). Although temperature influences flow parameters, its most significant interference occurs in resistivity, which is also affected by other factors, including the particulate characteristic. Actions to adjust the temperature must therefore observe the overall behavior of resistivity, to drive actions.
