ABSTRACT:
An electrostatic precipitator is provided utilizing an improved material for the collecting electrodes and other elements of the precipitator. The new material is a fiberglass reinforced resin with a conductive and corrosion-resistant surface layer consisting of resin containing graphite powder and one or more veils, or thin mats, of graphite at or near the surface. A relatively highly conductive, corrosion-resistant surface layer is thus provided for the electrodes while the material is also a suitable structural material for other parts of the precipitator such as the casing. Tube sheets and supports for tubular collecting electrodes may also be made of this material with provision for grounding the electrode surfaces at both the top and bottom of the tubes.
