CFD Investigation of ejector effects on High-Pressure Atmospheric Burners in different Air/Fuel ratio

This analysis illustrates the important role of internal ejector on production of pollutants such as CO, UHC and NOx, and peak flame temperature in high-pressure atmospheric burner with using of Computational Fluid Dynamics CFD in deferent Air/Fuel ratio. The combustion is modeled using two-step reaction mechanism and standard k-ε model is used for modeling turbulence. With using of internal ejector peak flame temperature and NO production of combustion is increased and CO, UHC emissions is decreased.
