Spark-Limiting ESP Controls

Click to expand.

Modern ESP voltage controls use sparking as a gauge for maximizing the applied voltage in the collecting fields. This provides maximum ESP collection efficiencies. The controls can sense a spark and extinguish (quench) it before any damage occurs.

Optimal spark rates for specific ESPs and/or bus sections can be determined through an evaluation of voltage control data, ESP design and the process stream.

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."
