Abstract
In this work, radiative heat transfer in axisymmetric Controlled Profile Reactor, fired with a pulverized coal-combustion jet is studied. Radiation is investigated numerically by the Finite Volume Method (FVM). The developed numerical code is validated by comparing its predictions of the radiative heat flux with published experimental measurements. The non gray feature of the medium is analyzed using the Weighted Sum of Gray Gases Model (WSGG). Then the effects of the gas and particles distribution on the radiative heat flux and on the radiative source term are presented. Finally, the influence of the gas and particle distributions and of the temperature fluctuations on the radiative transfer is investigated.
