Abstract
This paper reports a numerical study of the heat transfer characteristics of porous radiant burners, which have significant advantages over conventional burners. The heat transfer characteristics are investigated using a one-dimensional conduction, convection and radiation model. The combustion phenomenon is modeled as spatially dependent heat generation. It is revealed that for maximizing the radiant output from the burner, large optical thicknesses and high heat transfer coefficients between the solid and gas phases are desirable. Also, low solid thermal conductivities, scattering albedos and flow velocities, and high inlet environment reflectivities produced high radiant output.
