Abstract

An analysis has been carried out to determine the performance of porous radiant burners (PRB) as a function of fiber size. PRB made with silica or alumina fibers were considered. The radiative properties of the fibers were determined using the electromagnetic wave scattering theory for two different characteristic temperatures, 1000°C and 1500°C. The properties were used in a combined-mode heat transfer model to calculate the amount of energy radiated by the PRB. It was found that fibers smaller than order of one micrometer in diameter produced significantly higher radiant output. For a characteristic temperature of 1000°C, in some cases, the increase in output was as high as 63 and 109 percent for silica and alumina fibers, respectively.
