Show INCINERATION OF LIQUID HAZARDOUS WASTES: V APORIZA TION AND COMBUSTION OF DROPLETS OF CHLORINATED HYDROCARBONS· by R. R. Steepert,N. W. Sorbott, D. P. Y. Changtt, and C. K. Lawtt tCombustion Research Facility, Sandia National Laboratories, Livermore, CA 94550 ttuniversity of California, Davis, CA 95616 ABSTRACf Experiments have been conducted with chlorinated hydrocarbons to investigate the combustion characteristics of liquid hazardous wastes. Single droplets of alkanes, monochloroalkanes, and tetrachloroethane (C2H2C4) are injected into the post-combustion region of a flat-flame burner with either 0% or 18% excess air. The vaporization and burning rate constants defined by the D2_1aw are calculated and compared. The data show that C2H2C4 does not burn at typical incinerator conditions. However, it combusts readily when combined with only a small quantity of regular hydrocarbon fuel. Combustion is enhanced when the hydrocarbon additive is less volatile than the C2H2CLt • For presentation at the American Flame Research Committee International Symposium on Incineration of Hazardous, Municipal, and Other Wastes, Palm Springs, CA, November 2-4, 1987. |
