Abstract

This numerical study investigates the impact of four proposed porous burner designs, which are based on a diamond lattice structure similar to what could be obtained with additive manufacturing technology, on H 2/CO syngas production. The performances of all the burners were compared, and the results showed that for a given porosity, the recir- culation efficiency increased with increasing the pore density. Decreasing the porosity by a factor 2 increased the recirculation efficiency thanks to the presence of higher thermal inertia and local temperature, which allowed to achieve a 53% fuel conversion. Promising results were obtained with the new linearly varying pore diameter matrix, with an observed conversion efficiency of 63% and a reduction in the soot precursor production. This latter behavior itself resulted from an increase in the size of the reaction zone, where elevated temperatures led to high concentrations of H 2 and to the partial oxidation of C 2 species.
