A multifaceted experimental and theoretical program directed toward the understanding of rotary kiln performance is underway. Following a general overview of the program, we describe in more detail the program components including: In-situ measurements from an industrial-scale rotary kiln located at the Louisiana Division of Dow Chemical USA in Plaquemine, Louisiana; laboratory-scale desorption characterization and kiln-simulator studies; and incinerator modeling efforts. Using water-cooled probes, hot-zone samples have been obtained from both the full-scale rotary kiln and the afterburner and have been analyzed subsequently using GC and/or GC/MS techniques. We report on these preliminary measurements in some detail.

With landfill costs increasing and regulations on landfilling becoming more stringent, alternatives to conventional hazardous waste treatment strategies are becoming more desirable. Incineration is presently a permanent, proven solution for the disposal of most organic contaminants, but also a costly one, especially in the case of solids that require some auxiliary fuel. The goal of this research is to develop an understanding of the phenomena associated with the evolution of contaminants from solids in the primary combustor of an incineration system. A four-fold approach is being used. First, a bench scale Particle Characterization Reactor was developed to study the transport phenomena on a particle basis, where the controlling processes are mainly intraparticle. Second, a Bed Characterization Reactor was built to examine the controlling transport phenomena within a bed of particles, where the processes are primarily interparticle. The results of these studies can be applied to any primary combustor. A pilot-scale rotary kiln was developed to study the evolution of contaminants from solids within a realistic temperature and rotation environment. Finally, in-situ measurements are being obtained from a full-scale rotary-kiln.
This paper describes results obtained in a study using a commercial sorbent contaminated with toluene. The data are from the Particle Characterization Reactor and the Rotary-Kiln Simulator. The results show that the method of contamination and charge size does not have a large effect on desorption, while temperature and contaminant concentration are important parameters in the evolution of contaminants in a rotary kiln.

Temperature and stable species concentration data are presented from various locations within a full-scale rotary kiln firing natural gas/carbon tetrachloride/air. The data are being collected as part of a cooperative program involving university, industrial and government participation. The overall goal of the program is to develop a rudimentary understanding of and a predictive capability for rotary kiln and afterburner performance as influenced by basic design and operation parameters. The data clearly demonstrates that severe non-uniformities exist at the kiln exit under certain operating conditions. Even so, the data further indicate that high destruction efficiencies were achieved through adequate secondary combustion processing. The data further show that flow perturbations from within the kiln can persist well into the afterburner section and even into the stack.
