Effect of Dust Grains on the Electrical Properties of Torch Discharge

Abstract

Measurements of capacitance and active resistance of the high frequency torch discharge burning in the air while it had been polluted by the dust of dielectric and conducting materials were made. Increasing of active resistance of the torch discharge while it had been polluted by the dust of nickel was determined. The coefficient of conversion of electromagnetic energy into thermal energy was calculated. It has been shown that the maximum coefficient of conversion of the electromagnetic energy into thermal energy can be observed when the degree of dust pollution is 6·10{−6}.
