ESP & Fabric Filter Considerations for Meeting Environmental Regulations: MATS, MACT, Regional Haze, and European BREF

image-asset (3).jpeg

This informative webinar presented by Aaron Benedict and Jeffrey Shellenberger of Amec Foster Wheeler, will examine how ESPs and Fabric Filters can effectively be integrated into a multi-component Air Quality Control System. Co-benefits of each technology will be addressed including:     

  • ESP & Fabric Filter design considerations for compliance strategies

  • Choosing the best combination of technologies based on the plant’s flue gas pollutants

  • Options for upgrading or retrofitting ESPs or Fabric Filters

  • Impact of DSI/ACI & additional PM loading on ESPs & Fabric Filters

  • Factors driving the selection of wet ESPs (PM2.5, sulfuric acid mist, plume/opacity control, etc.)

  • Considerations when converting from ESP to Fabric Filter

Below are some of the questions discussed during the webinar:

  • How would replacing conventional T/Rs with High-Frequency T/Rs affect the electrical system?

  • For future low PM emission requirements, will we have to upgrade to membrane filters?

  • What are some of the design challenges associated with high-ratio polishing baghouses?

  • What is the most reliable ash transport/handling system for a biomass (straw, wood, grass, etc.) power plant?

  • What do you feel is the "most-used" sorbent injection point? Upstream of APH or downstream?

  • Which strategy would you advise to be most suitable when converting a coal plant (with existing ESP) to full white wood pellet firing?

  • Have you had instances of ESP efficiency and operation being affected by heavy thunderstorms? Opacity issues from thunder and heavy rain—any thoughts on the root cause of such problems?

  • Can you comment on H2O quenching spray in front of the ESP, to reduce velocity and/or provide a cooler temperature for the sorbent?

  • Does the pleated P84 bag significantly increase the area of the filter fabric? Does this significantly affect the pressure drop across a compartment?

  • In a FF-only application, what do you consider to be the most efficient means of performing the required PM monitor RATAS?
