Incineration of Liquid Hazardous Wastes: Vaporization Combustion of Droplets of Chlorinated Hydrocarbons

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 C2H2Cl4.
