Abstract

Abstract: The numerical simulation of the mixing process of atmospheric gas stove is established with the help of CFD simulation software. The reliability of the numerical simulation is verified by comparing the simulation results of the primary air coefficient with the experimental data. The mixing process of gas stove under different working conditions is simulated, and the influence law of hydrodynamic parameters (primary air coefficient, mixing uniformity and Reynolds number) on performance parameters (NO_x and CO emission) of gas stove under different working conditions is analyzed, showing that reducing the mixing heterogeneity can inhibit CO emission, and the other two parameters can promote CO emission. The overall law of all parameters and NO_x emission is opposite to that of CO emission, but the NO_x emission is the lowest at half open, which is due to the fast combustion speed and short contact time between reaction products and chemicals under this working condition.
