Non-attainment air quality regions will require the implementation of ultra-low-NOx boiler burner systems. Currently, only costly Selective Catalytic Reduction (SCR) systems can achieve 9 ppm NOx emissions. Alternative and inexpensive low NOx burners, that can meet the regulations without SCR, are urgently needed by the utilities industry.

Altex Technologies Corporation has identified the Minimum Emissions Burner System (MEBS) that has the potential to achieve very low NOx at low cost. Phase I test results have shown the ability of MEBS to reduce NOx to below 9 ppm. Most importantly, these results are achieved at a much lower cost than SCR, of ultra-low-NOx burners under development. Using the Phase I test results and cost data, it was estimated that the MEBS would be 70 to 90 percent lower in cost-to-remove-a-ton-of-NOx than FGR-based burner and SCR, respectively. This substantial cost advantage will drive the commercialization of the MEBS.

With the participation of Riley Stoker Corporation, a leading boiler manufacturer, Altex will further develop the MEBS under the proposed Phase II program. During this program, the MEBS design will be refined and tested at Riley's pilot-scale combustion facility. Economic data will then be refined and the economic benefits of the burner will be quantified. Lastly, Altex and Riley will prepare a plan for burner commercialization.
