In order to calculate the collection efficiency in an Electrostatic Precipitator (EP), it is necessary to take into account the effect of gas-sneakage which pass through the upper and down side of effective collection space. There have been reports on the calculation of the collection efficiency with the effect of gassneakage. However, since the calculation method used in these reports is relatively complicated and needs to input the dust particle-size distribution, in practice it is difficicult to apply the method easily. In this paper, the effect of gas-sneakage on the collection efficiency in EP is calculated on the base of new corrected formula of Deutsch's equation, which gives collection efficiency over the wide range of specific collection area (SCA), by using the apparent migration velocity of dust particle for parameter. The results of calculation are graphed and the several impotant characteristics related to the effect of gas-sneakage on the collection efficiency are explaned by the examination in these graphs.
