Abstract
Presented in this paper are the results of a theoretical study on using coatings to enhance the emittance of porous radiant burners. Consideration is given to burners made of silica fibers, and applying coatings to the fibers. Coating materials considered are silicon carbide, graphite, and platinum. The radiative properties of the fibers with and without coatings are computed using a radiation scattering theory. The radiative properties are then used in a P-3 solution of the radiative transfer equation to predict the emittance of the burners. It is shown that graphite and platinum coatings enhanced the emittance by a factor of three for a burner temperature of 1000 K, and by a factor of six for a temperature of 1500 K. It is also shown that it is possible to protect the graphite and platinum coatings from oxidation by applying a silica coating over them.
