Abstract
Radiative heat transfer in a turbulent pulverized coal combustor is analyzed using the Discrete Ordinate Method (DOM). Various combustion gases, coal particles and soot as absorbing-emitting-scattering medium, involved in the combustor play a significant role in the thermal radiation. In this paper, the effect of particle radiative properties on temperature field is investigated. The results have shown that the soot particles have a great influence on the wall radiative heat flux and the temperature field in the furnace. However, the effects of the difference of scattering phase functions by pulverized coal particles on the temperature field are found to be insignificant.
