The surface combustion characteristics of a methane-air mixture on a porous ceramic plate in a cylindrical furnace were studied. The flammability region not only expanded but also the surface temperature of the ceramics rose due to the recirculation effect of thermal radiation from a furnace wall, compared with the case of the open atmosphere. The peak of the surface temperature shifted to a lower equivalence ratio or a higher heat load than that for the open. It is suggested, however, that the structure of the surface combustion in the furnace would be similar to that in the open atmosphere. The influence of input heat loads on the surface temperature was described by a function of the ratio of the net radiant heat loss on the surface to the load. The bottom surface temperature of the ceramics was reduced with increase in the heat load.
