Simulation of temperature field of rotary kiln burner based on finite element method
In order to realize the visualization of the temperature distribution inside the rotary kiln during operation,the numerical simulation method is used to study.Numerical simulation of rotary kiln burners was carried out based on the finite element method.The weak form of fluid heat transfer equation was derived by the Lagrange function of the finite element method Galerkin method.The mesh division quality was compared,and the combustion simulation of the casing burner was realized by using the COMSOL finite element software.The temperature is kept at 1400-1800K,and the temperature in other areas is about 1100K.The simulation results are consistent with the actual situation.The polynomial fitting of the relationship between gas,air intake and temperature distribution shows that the intake velocity is linearly related to the average temperature in the kiln,and is related to the fluctuation of the maximum temperature in the flame zone.The temperature field simulation of rotary kiln burners provides a scientific basis for improving the roasting efficiency of steel mills,and provides a template for other scholars to use COMSOL software for simulation research.
