When an SCR system is underperforming, the first thought is a problem with the catalyst. This webinar will explore how issues throughout the entire SCR system can affect performance and what your plant can do to reduce ammonia consumption, extend the life of your catalyst, avoid ammonia injection grid (AIG) plugging, and more efficiently manage fast starts and varying/low loads.


1. Understand areas of an SCR system that can cause performance issues.
2. Understand the mechanics of ammonia injection grids and how to avoid plugging.
3. Understand impacts of load changes and frequent starts on SCR performance and how to address it.
4. Learn from in-depth case studies where AIG upgrades improved SCR performance.
