Nationwide+Boiler+Logo.jpg

Specific topics addressed will include:

  • An overview of current and future anticipated NOx emissions regulations

  • Understanding NOx reduction control strategies and comparison of control technologies

  • Understanding “next generation” SCR design and performance expectations

  • NOx technology options utilizing alternative reagents

  • Operating conditions and their effects on SCR sizing, design and lifecycle costs

  • Case studies:

    • Midwest Refinery NOx and Efficiency Project

    • Northern California “New” SCR Retrofit

In this informative webinar, Sean McMenamin, Nationwide Boiler’s Director of Operations and Environmental Solutions, will discuss key considerations in making smart decisions for your SCR design.

Below are some of the questions discussed during the webinar:

  • What are the typical materials used for the construction of the structural components of the system?

  • If an SCR is implemented, is there a benefit in utilizing in-furnace NOx reduction methods such as Low NOx Burners (LNBs) or Flue Gas Recirculation (FGR)? Is there a substantial return on investment (ROI) in reduced ammonia consumption?

  • When selecting the best ammonia distribution system for your plant (Anhydrous Ammonia, Aqueous Ammonia, or Urea to Ammonia), what are the plant considerations?

  • What is the impact of adding an SCR to a natural draft fired heater? Is there a loss of capacity?

  • What additional draft or pressure is needed to retrofit an SCR to avoid losing draft or capacity?

  • Do you have experience solving problems with low-temperature corrosion after the SCR catalyst due to the high conversion rate of SO2 to SO3, which harms the operation of flue gas ducts and ESPs?

  • What is the impact of ammonia slip on downstream equipment in power plants, and how is it measured?

  • Is a catalyst sootblower ever needed for oil-fired units?Have you seen SCRs downstream of economizers?What are the effects of urea that is not converted to ammonia in the catalyst?

  • Can you guarantee the life of the SCR catalyst in the presence of toxic metals in the flue gas?

  • What is the typical time required to erect the entire equipment for a supercritical power plant (800 MW)?

  • Would the byproducts of SCR have any impact on ash properties?
