Spark-Limiting ESP Controls

Spark-Limiting ESP Controls

TR Set-revised

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.

Optimizing SO3 Systems in Multiple-Unit Plants

Duke Energy Beckjord: SO3

Installing separate SO3 flue gas conditioning systems on two units at Duke Energy's Beckjord Power Plant fixed ongoing struggles to maintain acceptable stack emission levels. Neundorfer provided one of the SO3 systems, and helped Duke Energy save mon ...

"The greatest benefit is that we can now prevent emissions from ever exceeding established opacity limits, and it does not require our round-the-clock attention."
