This work has been carried out towards a low emission, high energy density combustion burner that does not operate with free flames. The entire combustion takes place in a porous matrix. A one dimensional model is used to solve the governing equations for porous medium and gas flow. Combustion in the porous medium is modeled as a spatially dependent heat generation zone. In order to analyze the transient thermal characteristics of porous burners, the coupled energy equations for the gas and porous medium based on two–flux radiation model are solved numerically and the effect of various factors on the performance of porous radiant burners are determined. Comparison between the present results with those obtained by other investigators shows a good agreement.
