Abstract

A comparative study of numerical and analytical results for a porous radiant burner (PRB) is presented. It is shown that the analytical method captures all the features of the system and can be used for quantitative applications. Two solutions are found, one is located close to the inlet of the burner and the second one is close to the outlet. The effects of the molar flow rate, the interphase heat transfer coefficient (hs) and the location of the flame in the matrix, on the radiation efficiency (RE) of the burner are studied. Local maxima in the RE vs. hs curves indicate that intermediate values of hs will be the optimum choice. Other trends are also analyzed and some recommendations are made.
