Description:

The objective of this study is to demonstrate that the performance of incinerators can be improved by retrofitting them with a pulse combustor which will excite acoustic pulsations within the system. Based upon evidence provided by related studies, these pulsations are expected to increase the mixing rate between the fuel and oxidizer, and the burn rate of waste; improvements which are expected to increase the incinerator output, increase the degree of destruction of hazardous substances, and reduce the required amount of excess air. The proposed studies will investigate the incin- eration of three surrogate wastes (PVC, a mixture of toluene and corncob, and a mixture of fuel oil no. 5 with corncob) in a small scale incinerator equipped with a frequency tunable, pulse combustor. Tests will be repeated under the same operating conditions with the pulse combustor oper- ated in a steady and a pulsating mode. Investigated pa- rameters will include the flow rates of the fuel and air, the type and amount of waste, and the amplitude and frequency of pulsations. The performance of the incinerator will be determined from measured time dependencies of the exhaust flow temperature, CO CO2, O2, THCs and soot concentra- tions, and the amplitudes and frequencies of pulsations in the combustor and incinerator. The effect of pulsations will be determined from comparisons or the incinerator perfor- mance with pulsations present and absent in the system.
