Precision Flame Shaping and the Effect on Emissions

Accurate flame fit within the chamber enclosing the heat release zone is essential to reduced emissions. This paper presents generalized relationships between NOx and flame fit, CO and flame fit, NOx and flame temperature, CO and excess air and NOx and excess air. These analytical advancements in flame shaping have been developed for dual fuel applications, and are equally valid for single fuel burners. Many new and retrofit installations where this technology has been applied are benefiting from simultaneously low levels of all regulated pollutants. The precision flame fit analytical methods have now been confirmed repeatedly in validation testing and field operations on single and multi-fuel burners.
