APPLICATION OF PULSE COMBUSTION TO INCINERATION OF LIQUID HAZARDOUS WASTE
DeBenedictis*, C. APPLICATION OF PULSE COMBUSTION TO INCINERATION OF LIQUID HAZARDOUS WASTE. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/R-94/060 (NTIS PB94-164415), 1994.
The report gives results of a study to determine the effect of acoustic pulsations on the steady-state operation of a pulse combustor burning liquid hazardous waste. A horizontal tunnel furnace was retrofitted with a liquid injection pulse combustor that burned No. 2 fuel oil. The fuel oil was doped with surrogate principal organic hazardous constituents (POHCs). The POHCs used were carbon tetrachloride and chlorobenzene. Baseline conditions were tested when only fuel oil was burned as well as hazardous waste operations. For each test condition, the burner was operated in both a pulsing and nonpulsing mode. Large amplitude acoustic pulses were generated by adjusting the burner frequency to match the natural frequency of the combustion chamber. The combustion gases were sampled to quantify organic and particulate emissions. The results showed destruction and removal efficiency values that were greater than six nines (99.9999%) for both pulsing and nonpulsing operations. The pulse combustor for this study was equipped with a fuel vaporization unit which may have enhanced the destruction capabilities of the burner. It is not known if operating without a vaporizer or under non-ideal combustion conditions would degrade burner performance.
