Fabric Filters

For particulate removal, fabric filters offer a flexible alternative to electrostatic precipitators (ESPs), particularly when dust characteristics are challenging or variable.

Lower than 5 mg/Nm3 particulate emissions possible, greater than 99.97% particulates removal efficiency, high PM10 and PM 2.5 removal rate

Filters up to 12 meters tall for reduced footprint and operational costs

Large fuel flexibility and ability to handle varying boiler loads

GE offers both high ratio (pulse jet) and low ratio (reverse air) options, depending on the application. Fabric filters may be used stand-alone or integrated in Dry Flue Gas Desulfurization (DFGD) solutions (NID* or SDA), for dry scrubbing in the aluminum industry (Abart*), or as the principal and polishing filters in mercury control solutions (Mer-Cure* or Filsorption*).

  • Renowned Optipulse* filtration technology with gravimetric flow and Optipow* plunger valves for efficient bag cleaning
  • Stand-alone or integrated in multi-pollutant systems
  • Latest EFFIC controller and ProMo software for superior FF performance
  • The combination of Optipow valves and EFFIC controller on a new or existing FF provides better bag life compared to other available solutions
