“…Sathe et ai. [3] reported a maximum radiant efficiency of 40 9% for these burners, however, our observation that leaner mixtures produced higher efficiencies is consistent with their work. The 21% excess radiant output measured by the FTIR was in large part attributed to the fact that the emission gases such as COz and water also radiate heat to the FTIR.…”

Abstract. The purpose of this study is to analyze two-dimensional rectangular porous radiant burners in order to investigate the thermal characteristics of this type of burners in starting time period. Since the solid and gas phases are not in thermal equilibrium, two separate energy equations for these two phases are solved numerically with alternative direction implicit scheme. The gas is considered non-radiative medium, and for computation of radiative heat ux through the solid phase, the Radiative Transfer Equation (RTE) is employed and solved using the Discrete Ordinates Method (DOM). It is obtained that, due to the dominant radiation e ects, the required time to reach the steady gas temperature is very low. Furthermore, the e ects of optical thickness and scattering albedo on the performance of Porous Radiant Burner (PRB) are investigated.

“…1). [4] The burner can be conveniently subdivided into three parts, namely the entrance zone, the porous combustion support, and the oxit zone. First, the gas combustible is injected in the porous support from the upstream (or entrance) zone while the burner ignition is performed at the porous support boundary in downstream (or exit) zone.…”
