Troubleshooting ESP Wire Failures

Troubleshooting ESP Wire Failures

Common wire failures in discharge electrode systems can be a very serious problem with the potential to force the shutdown of a precipitator’s complete electrical field. Common causes of wire failures include:

  • Warped plates that change the wire-to-plate distance
  • Overvoltage
  • Metal fatigue
  • Chemical attack
  • Mechanical failure
  • Eroded wire frames
  • Full hoppers
  • Improper weight sizes
  • Oscillation
  • Swinging lower wire frames
  • Corrosion
  • Improper rapping

Holnam Cement

Following a kiln outage in early 1997, a fire destroyed four precipitators at Holnam Cement in Clarksville, Missouri. Within two days, Neundorfer and Holnam had a plan for replacing ESP components. Eighteen weeks after the fire, the rebuild was compl ...

"The silver lining of the cloud caused by the fire is that now Holnam is able to shut off any one of the precipitator units for maintenance while continuing production, which had previously not been possible."
