A fuel spray mixture suffered by partial oxidation through a catalytic honeycomb was studied experimentally. The palladium catalyst supported on the cordierite honeycomb monolith was used. Kerosene vapor was introduced into the ca talytic honeycomb. The parabolic shape blue flame that was supported on the catalytic honeycomb was formed even if the equivalence ratio of the mixture was less than stoi-chiometry. To clarify a reaction process in an combustible gas between the honeycomb and the blue flame, CO, HC (C1-C7) and NO were analyzed. When blue flame appeared, CO and HC concentration were increased between the honeycomb and flame. Further, high molecular species (C8-C15) in the combustible gas were trapped by the water-cooled condenser system and they were analyzed by the gas chromatograph and mass spectroscopy. Spontaneous emission spectra from the blue flame were measured. Strong spectral peaks of OH, CH and H2O radicals were observed in it. To compare with the spectra, spontaneous emission spectra from the pre-vaporized flame of kerosene mixture were measured.
