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

Keys to Sustained Performance Improvements

Midwestern Utility Precipitator Upgrade

A Midwestern utility had a problem: precipitator performance was sub-par, resulting in reduced power generation and undesirable opacity levels. Called in as a consultant, Neundorfer helped the utility identify causes and fix the problem through inter ...
