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.
As today’s global regulatory environment places more stringent limitations on NOx emissions (with pending NOx limits in the range of 30-200 mg/Nm3), operators of both utility and industrial boilers are facing new challenges which require innovative solutions to increase NOx control and combustion efficiency. The solution lies with developing innovative strategies which embrace a step-wise, layered approach that will result in the lowest cost options for NOx control. A comprehensive engineering analysis often requires CFD modeling, piping and windbox analyses, and finite element analyses to define the best options for specific boilers and targeted fuels. These methods, combined with the capability to provide innovative hardware and equipment modifications, form the key elements in developing a holistic NOx control strategy.

Step-wise NOx reduction is only part of an effective approach to reducing NOx emissions and increasing combustion efficiency. Direct NOx reduction methods including low-NOx coal, gas and oil burners, overfire air, flue gas recirculation, windbox modifications, and fuel/air balancing all are optimized in establishing lowest cost options. Application of post combustion techniques such as SNCR and SCR complete a fully phased approach but the degree of NOx reduction must be evaluated versus capital and operating costs to define any compliance strategy.
In this informative webinar, Robert Santangeli, Technical Director at STEP Combustion (a division of EES, Inc.), will review key elements and engineering aspects for implementing a step-wise approach to NOx control. Topics presented 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
Additionally, one or more select NOx reduction case studies will be discussed in detail.
Attendees are encouraged to ask questions which will be answered during the Q&A session of the webinar.
