In this paper, we show the experimental results on the size distribution of collected and non-collected particles in a two- stage type ESP (electrostatic precipitator). In order to reveal the collection mechanism the dust size distribution of each part of ESP was qualitatively investigated by means of the scanning electron microscope images.We used the wire-plate configuration in the charging electrode and the plate-plate configuration in the collection electrode. In charging section, the front part of grounded plates has collected particles of under 10μm and the middle and rear parts of that have collected bigger particles. In collection section, the all parts of grounded plates have collected finer particles selectively.Interactive effects of air flow, Coulombs force and corona wind play a key role in these results.
