The effect of geometry parameters and inlet temperature on NOX emission at Micro Combustors

The present study investigated on numerical modeling of flame temperature and pollutant emissions of H2-air mixture combustion in a series of chambers with same shape but various diameters and length of combustion chambers under different inlet temperature and adiabatic wall condition. The simulation results indicate that increasing the flame temperature by adding diameter and length of combustion, decreasing the NOX emission by depleting chamber size and inlet temperature totally. Also, the zero emission of the prompt NOX emission by using hydrogen as fuel in all combustors is achieved
