Abstract

The electrical characteristics and particle collection efficiency of a wide-plate spacing electrostatic precipitator are numerically investigated, and the results are compared with those obtained experimentally. The electric potential and field strength near the collection plate increase with increasing the plate spacing. The electric field strength of a discharge electrode of a twisted pin type is larger than that of a rectangular type. As the roughness factor of the discharge electrode wire becomes small, or the plate spacing becomes narrow, the corona current of the precipitator increases. The numerical results agree well with those obtained from experimental method.
