Stringently regulated ozone nonattainment air quality regions will require the implementation of ultra-low-NOx systems. Currently, only costly Selective Catalytic Reduction (SCR) systems can achieve very high levels of NOx reduction. Inexpensive low NOx burners, that can meet the regulations without SCR, are urgently needed by industry. Recently, progress has been made towards developing a sub-9 ppm NOx gas-fired burner. However, the flexibility of this porous matrix surface burner is very limited, and its wide use is not expected.

Altex Technologies Corporation has identified the Multiple Flame Burner that has the potential to achieve very low NOx, while maintaining the flexibility needed for widespread use of the burner. The burner uses the interaction of several flames to control emissions and enhance burner flexibility. To show the feasibility of this burner under the Phase I program, analyses will be used to refine the burner concept for an application of interest. A preprototype of the burner will then be fabricated and tested, under conditions simulating the application of interest. Lastly, the results of the analyses and testing will be used to evaluate the burner performance and costs, relative to existing burners with and without SCR.
