Numerical Simulation Analysis of Combustion in a Jet Ladle Baker

Abstract The combustion characteristics of the jet ladle baker were simulated and analysed using Fluent software for different burner configurations. Firstly, a coupled mathematical model of combustion, radiation and convective heat transfer in the jet ladle baking process was constructed using the energy equation, standard k-ε turbulence model, DO radiation model and component transfer model. Then numerical simulations were carried out for the effects of the angle of the obturator, the gap between the obturator and the gas pipe, the length of the gas pipe in depth, and the diameter of the combustion chamber in the baking process for the jet ladle baking burner model. The results demonstrated that the optimal combustion condition was achieved when the angle of the obtuse body was 60°, the gap between the obtuse body and the gas pipe was 20 mm, the length of the gas pipe extending into the combustion chamber was 50 mm, and the diameter of the combustion chamber was 300 mm. The simulation and analysis results can provide reference value for the design of jet ladle baker.
