Fuels Combustion Research.
Abstract
Further oxidation studies of the n-alkylated aromatics reveal insights with respect to the oxidation of the alkyl side chains. Toluene is unique in its oxidation due to the nonreactivity of the benzyl radical that forms. The higher normal alkyl aromatics all form styrene and allyl radicals during the initial stages of oxidation. Thus the oxidation of these fuels will all be similar to ethyl benzene. The first results on the oxidation 1-methyl naphthalene have been obtained. A study on the oxidation and pyrolysis of butadiene, an important aromatic intermediate and soot precursor, has been completed. More extensive experimentation on the sooting tendencies in premixed and diffusion flames has been performed. The new fuels used were the cycloalkanes, the cycloolefins, purified 1,3-butadiene and 1-methyl naphthalene. A new model for sooting under premixed conditions reveals that original fuel structure does not play a role in soot production, but the number of carbon-carbon bonds in the fuel do. Diffusion flame results confirm that fuel pyrolysis rates and intermediates determine the sooting tendency in this combustion system. The new theory of boron ignition and combustion has been improved further. Appropriate droplet generators for boron and carbon slurries have been developed. Originator-supplied keywords include: Aromatic fuel oxidation, Fuel pyrolysis, Slurry combustion, Soot formation, Boron and carbon combustion, and Turbulent reacting flow.
