Modification and numerical simulation analysis of low NOx burner
Based on the ultra-low nitrogen retrofit project of 10 MW gas burner for organic heat carrier furnace in active service in a chemical fiber company,the ultra-low nitrogen retrofit scheme of organic heat carrier furnace,the flame changes in furnace before and after retrofit and the amount of nitrogen oxides produced were sorted out and analyzed,and the retrofitted burner was properly simplified and then modeled.Numerical simulation is carried out by fluent software,and the formation law of nitrogen oxides with the change of load of organic heat carrier furnace is analyzed,which provides theoretical and experimental support for the ultra-low nitrogen burner and its use,and provides reference for further optimization and transformation of ultra-low nitrogen burner.
