An analysis of the electric field strength distribution in the electrostatic precipitator (EP) is necessary in order to develop the more efficient, lower cost and smaller EP than usual ones. The analytical method of the electric field strength in the industrially used EP has been experimentally achieved, but a general method of calculation of the electric field strength is not established at present. Our present study is devoted to the establishment of a calculation method for the electric field strength distribution in EP with any electrode structure. In our previous paper, in the case where the space in cylindrical EP is filled with clean gas, a good agreement was obtained in the comparison of the calculated values by means of the method of successive approximative theoretical equation derived by Uhlman and Mayer. In this paper, we made this calculation method better and further tried to calculate the electric field strength distribution in EP involved dust gas with the method of successive approximation. At the first, we measured the radius of ionization region by taking photographs of corona glow points and determined electric field strength of the boundary between ionization and space charge region. Then, the approximate boundary condition of space charge density on discharge electrode was determined by using this electric field strength and the calculation of electric field strength distribution was performed on cylindrical EP. The propriety of this calculation is criterized by same means of Steel Ball Dropping method at our previous paper. The field values calculated by means of the method of successive approximation making use of the approximate boundary condition agree well with the measured values within 4.9% error (average 2.8% error). As the result, it might be concluded that this calculation method is applicable to the analysis of the electric field strength in any other complicated system of EP.
