Low NOx Commerical Burner

70848 This project will develop a high efficiency, ultra-low emissions, oil burner for large residential and commercial buildings. The new burner will achieve significant improvements in energy efficiency by incorporating fan atomization of fuel and an automotive fuel injection technology to substantially improve the firing rate modulation. The burner will also achieve dramatically improved environmental performance with reduced particulate and NOx emissions. In Phase I, larger low pressure, air atomizing nozzles will be built. These will be a simple extension of nozzles used to date at lower rates. Then, the burner head (including the air tube, electrode holders, secondary air introduction arrangement, and flame tube) will be designed, built, and combustion tested. Commercial Applications and Other Benefits as described by the awardee: Commercial sector oil consumption for this equipment was 0.9 quads in 1990, or about 6 billion gallons. This technology, along with a zero nitrogen content fuel, has the potential to eliminate over 50,000 tons of NOx emissions from the environment each year if fully deployed in the commercial building oilheat market.
