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

Creative Approach, Thoughtful Analysis Saves Two Coal Plants

Power producer, Emissions Compliance Success Story

When the plant's initial assessment indicated MATS compliance would require high-cost upgrades, the future of two plants was uncertain. By modeling improvements over the entire process, Neundorfer identified a low-cost compliance program that would ...
