Combustion in boiler and fluids heaters consumes approximately 5 TCF of gas per year and generates approximately 350,000 tons of NOx. To meet ambient air quality standards, particularly those for ozone, low-cost ultra-low NOx burners are needed for these applica-tions. This will reduce the costs and increase the competitiveness of industry that might otherwise be forced to use the expensive Selective Catalytic Reduction (SCR) NOx control techniques.

Altex has identified and ultralow NOx burner for fluids heating, called the ULNB, that has the potential to reduce NOx to 5 ppm. The burner does not require flue gas recirculation, steam injection or exotic materials and is projected to have a pollution control cost of approximately $320/ton of NOx removed. To show the feasibility and benefits of this burner under the Phase I program a burner will be fabricated and tested under conditions characteristic of a watertube boiler. Results of analyses and testing will be used to evaluate the burner performance and costs relative to conventional and low NOx burners and SCR.
