Research Project


This project demonstrated the performance of an ultra-low NOx burner that achieves very low NOx from boilers without the use of massive flue-gas recirculation (FGR), exotic non-durable materials, or post-combustion chemical treatment. The BACT limit of 9 ppm was achieved with 10 percent FGR, and 5 ppm was achieved with 25 percent FGR. The predicted cost of the technology is $260/ton of NOx, an order-of-magnitude less than competing technologies. The technology was first developed by Altex Technologies, Inc. of Santa Clara.
