Numerical Analysis on Effect of Radiative Heat Transfer on Turbulent Pulverized Coal Combustion

摘要

Radiative heat transfer in a turbulent pulverized coal combustor is analyzed using two different radiation models, Six-flux model and Discrete Ordinate method. Numerical results with and without radiation effects are compared with experimental data. The effect of particle radiative properties on temperature field is also investigated. The results have shown that the difference in temperature distribution between two models is small and the particle thermal radiation has a great influence on the pulverized coal combustion.
