Abstract LOMA-MLB hot gas generator is suitable for blast furnace gas. Through computer modeling and mesh division, the combustion of blast furnace gas in the hot gas generator is numerically simulated by using Fluent software to verify the air-fuel ratio and flue gas temperature reference value required for air distribution during hot gas generator commissioning. The simulation results show that the combustion reaction mass transfer process is basically completed, the experimental data is slightly higher than the heat value calculated by the simulation data, and the simulated combustion burnout rate is high. The maximum temperature of the combustion flame center is 1 595K, and the NOx content at the outlet is only 0.008 6ppm. The design of the bluff body of the gas burner is conducive to the mixing of fuel and air and the continuous stability of the flame.
