Abstract
In recent years calculations showed that the emissivity of the furnace refractory can have an influence on heat transfer, because of banded properties of gas radiation. Some aspects of this phenomenon have been studied using a spectral well-stirred furnace model of a combustion compartment. The influence of spectral lines in the emission bands has been examined. These lines have been found to increase spectral effects considerably. Further, a discrepancy that exists between grey and spectral calculations has been explained in terms of the definition of gas emissivity. The spectral properties of the refractory appear to raise the heat flux to the load when compared with a grey refractory.
