ULTRA LOW-NOX BURNER FOR BOILER AND PROCESS HEATER APPLICATIONS

Combustion in boiler and fluids heaters consumes approximately 5 TCF of gas peryear and generates approximately 350,000 tons of NOx. To meet ambient airquality standards, particularly those for ozone, low-cost ultra-low NOx burnersare needed for these applica-tions. This will reduce the costs and increase thecompetitiveness of industry that might otherwise be forced to use the expensiveSelective 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 fluegas recirculation, steam injection or exotic materials and is projected to havea pollution control cost of approximately $320/ton of NOx removed. To show thefeasibility and benefits of this burner under the Phase I program a burner willbe fabricated and tested under conditions characteristic of a watertube boiler.Results of analyses and testing will be used to evaluate the burner performanceand costs relative to conventional and low NOx burners and SCR.
