Abstract
A computer model has been developed that describes the microenvironmen t of a surface cavity in a porous radiant ceramic burner. The model su ggests that these cavities generate a nearly adiabatic condition leadi ng to high concentrations of gaseous radical species. Predicted degrad ation characteristics closely resemble those seen in commercial radian t burners. From these calculated gas compositions and substrate temper atures, three different modes for burner degradation are proposed.
