Demonstration of a Novel Ultra-Low NOx Boiler for Commercial Buildings
The project demonstrates burner technology that will reduce natural gas usage while meeting regional air quality requirements.
The ultra-low NOx burner (DSE burner) technology was successfully demonstrated and showed wide operational latitude in satisfying market needs and meeting requirements for <9, <12, and <20 vppm NOx. The DSE burner achieves comparable or slightly increased efficiency relative to other systems, such as flue gas recirculation (FGR) and high excess air (HEA) burners. The DSE burner also has lower blower pressure/power requirements compared to HEA burners, thus reducing electricity consumption and equipment cost. To bring the technology to market, GTI has partnered with Power Flame. Given the high performance of the technology and the low-cost design, the recipient is optimistic that the product could be brought to market with competitive pricing, enabling broad deployment. The final report is under review and planned for posting in the fall.
This project demonstrates a novel ultra-low-NOx burner design in a boiler for a commercial steam distribution system at Mission Linen Supply Inc. in Santa Barbara, California (the burner technology is referred to as dynamic stage entrainment (DSE)). The DSE burner offers a cost-competitive alternative to equipment currently available to the California commercial steam generation market, but not widely used. Extensive laboratory evaluation of the technology has shown the DSE burner design is capable of meeting less than nine parts per million NOx levels while operating with relatively low excess oxygen and high efficiency levels.
This technology will reduce costs of boiler operation through reduced natural gas costs. Commercial operators will also save money on costs of NOx mitigation. The DSE burner offers a cost-competitive alternative to equipment currently available to the California commercial steam generation market,
The technology aims to reduce natural gas usage which has the potential to reduce NOx levels and GHG emissions.
