The Development of a Low NOx High Intensity Burner

Tighter emission standards and rising fuel costs have created a market for high intensity burners which outperform standard turbulent flame burners. AECOmetric High Intensity Burners feature a swirling vortex which completely mixes the fuel and air to provide stoichiometric combustion efficiency and flame temperatures of about 3000 degrees Fahrenheit. The Conamara Group is engaged in a research program in conjunction with the National Research Council and Consumers Gas to reduce the NOx emissions from 100 ppmv to under 20 ppmv. Experimental results will be presented to illustrate the impact of secondary air schemes on the CO and NOx performance of the burner.
