Case E: Broken Stainless-Steel Wires from an Electrostatic Precipitator
Introduction Gas effluents from paper plants contain fine particles which are sometimes removed by an electrostatic precipitator. In these systems thin wires are charged to several thousand volts so that dust particles from flowing gases are attracted to the wires and the surrounding dust collector plates. Periodically, the wires and plates are vibrated to remove these particles into receptacles at the bottom (Fig. 7.48). Several of these wires failed in one such precipitator in an unexpectedly short time. The wires are manufactured in c…
