Electrostatic precipitator having apparatus for sensing electrostatic field strengths
An electrostatic precipitator (10) of the type having a casing (12) defining a precipitation chamber (6) wherein a plurality of discharge electrode frames (32) are disposed alternately between a plurality of collecting electrode plates (20). Paired probe devices (50) are mounted on the collecting electrode plates for sensing the strength of the electrostatic field generated by at least one discharge electrode wire (36) at at least one location on each of the collecting electrode plates (20) disposed adjacent thereto. The electrostatic field strength sensed by the paired probe devices are compared with each other to provide an indication of the degree of imbalance, if any, existing between the sensed electrostatic fields experienced by the bounding electrode plates. The existence of an imbalance and the strength of the electrostatic fields on the bounding collecting electrode plates and the degree of any such imbalance provide an indication of whether or not the discharge electrode frame is properly positioned within the assembly of collecting electrode plates.
