Topics presented in the webinar will include:

  • Background information including the effect of fly ash on SCR catalyst and systems

  • High dust coal application design strategies – How to bust the dust?

  • SCR operational information regarding high dust environments

  • Pluggage & Erosion Test Cases of DUSTBUSTER™

  • Results from the Test Evaluating DUSTBUSTER™ vs plate catalyst

  • High dust SCR catalyst applications and regeneration 

  • Commercial application and benefits of DUSTBUSTER™ - Field data and case studies

Ash accumulation during coal power generation, especially in “high dust” environments in the flue gas, can lead to erosion and plugging of the SCR catalyst with subsequent ash build-up atop the catalyst layers. Coal-fired power plants globally utilize a range of opportunity fuels to produce the lowest cost power. These coals have varying levels of ash, which can be a detriment to a power plant’s downstream air pollution control equipment, specifically SCR catalysts used to reduce NOx emissions.

Below are some of the questions discussed during the webinar:

  • What level of velocity distribution criteria is appropriate for high dust applications?

  • What is the pressure drop across the catalyst layers for DustBuster Catalyst?

  • What are some strategies to extend the life of the catalyst with lower plant capacity factors and extended plant shutdowns?

  • On a typical honeycomb changeout, what percentage of modules are damaged? Does DustBuster have significantly different integrity?

  • With use, wouldn't honeycomb lose its ability to fully regenerate, similar to plate type catalysts?

  • Can I get DustBuster with Mercury features?

  • Is there any data on how honeycomb stacks up against plate type catalysts with respect to regenerability?
