Abstract This paper describes results of an investigation of the effect of large amplitude resonant pulsations excited inside an EPA rotary kiln incinerator by a tunable pulse combustor (i.e., the Cello burner) upon puff emissions. Incineration tests were conducted with two surrogate wastes: toluene and polyethylene. Pulsations were excited inside the incinerator by operating the Cello burner at a frequency that equaled a natural acoustic mode frequency of the incinerator. Each test was repeated ten times, and each waste was incinerated with and without the excitation of large amplitude pulsations within the incinerator. The performance of the incinerator w as evaluated by determining the total amounts of unburned, gas phase, hydrocarbons, carbon monoxide and soot emitted during the test. Comparison of the incinerator emissions in pulsating and non-pulsating tests revealed that in the pulsations decreased the total amount of emissions (i.e., the magnitude of the puffs) in all tests. Furthermore, the pulsations reduced the soot emissions by amount varying between 30-75%, which is most significant as it is generally more difficult to incinerate the soot in the afterburner and the soot represents a higher health hazard. These analytical results were confirmed by visual observations of conditions inside the incinerator where the "atmosphere" was practically clear in pulsating tests and very smoky in non-pulsating tests. Finally, sampling line oxygen concentration measurements strongly suggest that the observed improvements in incinerator performance were due (at least in part) to the increase in mixing rates caused by the pulsations.
