Abstract
Measurements and calculations of radiative energy emitted and scattered by a hot suspension of calibrated alumina and two industrial samples of fly ash are presented. Excellent agreement was observed for alumina when using the available data of refractive index. For ash, the results are very sensitive to both carbon content and size distribution. The results suggest that carbon, even in low proportion, is a major constituent of fly ash regarding radiative heat transfer in pulverized coal furnaces. On the other hand, when scattering is significant, very reliable information concerning particle concentration and size distribution is required in order to predict accurate radiative fluxes.
