Keys to Combustion & Emissions Optimization: STEP-wise NOx Reduction, Fuel Switching and Combustion Optimization

image-asset.png

Webinar Topics covered will include: 

  • Understanding thermal NOx, fuel NOx, and prompt NOx mechanisms and their correlations to burner upgrades and staged combustion

  • Layering of complimentary NOx reduction technologies to meet stringent emissions requirements

  • Burner configurations and design and upgrades when switching fuels

  • Post combustion SNCR NOx reduction using SARIS = Source Assisted Reagent Injection System to maximize reagent (urea) utilization

  • SCR reactor design and catalyst management – when needed

  • Critical services for intelligent evaluations – emissions testing/combustion tuning, boiler & burner inspections, fuel/air balancing and coal mill tuning, furnace mapping

This webinar will help you make informed strategic decisions about employing a step-wise approach for NOx control to meet the specific needs for your boiler and fuel mix.

Below are some of the questions discussed during the webinar:

  • What is the recommended primary air velocity for coal at the burner exit?

  • We have a coal-fired boiler with high Loss on Ignition (LOI). What can we do to improve burnout?

  • For tangentially fired boilers, does STEP provide tilting or fixed gas burner arrangements?

  • Would STEP provide gas conversions for stoker-type boilers, and would you remove the grate?

  • Are there any limitations with over-fire-air and flue gas recirculation systems?

  • You mentioned that you have used a 40% urea solution for your SNCR systems. What is your typical concentration at the injector?

  • How do you determine where to locate SNCR injectors?
