Abstract

This paper investigates the effect of inclined angle of fuel jet on concentration of NO_x emission in high temperature air combustion furnace. Computational Fluid Dynamics (CFD) modeling was implemented to investigate the combustion process and NO_x formation in the furnace. The CFD model presented in this paper is validated by comparing the modeling results with measured data. The results show that the concentration of NO_x emission decreases by increasing the inclined angle of fuel jet. Besides, the concentration of NO_x emission drops with the decrease of oxygen concentration. Moreover, the effecting degree of inclined angle on NO_x formation increases with the increase of oxygen concentration.
