Experiment to Find What Works “ It’s Worth the Effort

Reverse Air Cleaning Optimization

  • Clean based on differential pressure
  • Optimize cleaning cycle (e.g. 15-30-45 seconds)
  • Achieve good compartment isolation during cleaning
  • During low loads, use default program to clean minimum one time per 2-4 hours
  • Control reverse air pressure to: 1.0:1-1.5:1 air-to-cloth area (+1.5 H2O max)
  • Acoustic horns can help reduce R/A pressure

Pulse Jet Cleaning Optimization

  • Clean based on differential pressure
  • Clean online if possible
  • Clean one row in each compartment at a time
  • Clean rows of bags non-sequentially
  • Use minimum pulse pressure needed to control differential pressure
  • Keep pulse duration short (e.g. 0.10 seconds)
  • Use clean, dry compressed air

Shaker Cleaning Optimization

  • Clean based on differential pressure
  • Minimize movement and duration of shaking
  • Use anti-collapse rings
  • Use deflation dampers
  • Acoustic horns can help reduce differential pressure

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."
