An electrostatic precipitator using substantially planar screens of similar charge positioned perpendicular to the gas flow direction. The screens have a similar charge of the same polarity, and particles flowing through the screens are charged, agglomerated and either collected on the screens or fall downwardly into collecting hoppers below the screens. The screens preferably have openings smaller than 3 millimeters and are spaced apart less than 10 millimeters. In an alternative embodiment, the screens have alternating polarities and are spaced about an inch or more apart to prevent sparkover.
