The effect of discharge-electrode interval on corona current

Publisher Summary This chapter presents the effect of discharge-electrode interval on corona current. According to the researches on characteristic of the distribution of electric field between wire-plate electrodes different discharging interval will greatly affect the homogeneous degreases of electric field. Thus, it produces the remarkable change to the unit corona current and the total current. Depending on a series of experiments and formulae analysis, the optimum value of corona current achieved through different interval of wire-plate electrode under natural conditions is defined. The surface current and the line current are discussed though two groups of the given data. The dust collection efficiency of a precipitator is mainly determined by surface current and the effective total energy of a precipitator is mainly determined by line current. The chapter also offers certain theoretical direction for the optimum design of electrostatic precipitator of wire-plate electrode.
