Abstract

In one aspect of the invention, a charger (10) for use in a system for separating particles from a fluid flow is disclosed. In one embodiment, the charger (10) comprises a body including an inlet (12) for receiving the particles, a chamber (14) in which the particles are received, and an outlet (20) for discharging the particles. A rotor (18) having a generally non-permeable surface is positioned in the chamber (14) and rotated for contacting and charging the particles. In another aspect of the invention, grid electrodes (116) with elongated fingers (120) are proposed for use in novel separation system. Related methods of charging and separating particles are also disclosed.
