“…These results will be reported in subsequent papers of this series. 14 " 15 Much the same information can be gleaned from the afterburner data pre-sented in Figure 14-17 and Table VI. Although taken on the same day, the afterburner measurements were not obtained simultaneously with the kiln measurements because of our concern of sample aging (previously discussed).…”

A multlfaceted experimental and theoretical program directed toward the understanding of rotary kiln performance Is underway. University, Industry and government participation Is Involved. This paper, the first In a series, presents a general discussion of the overall programmatic goals, followed by a brief description of the sub-programs 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 klln-slmulator studies; and incinerator modeling efforts. Water-cooled probes have been used to obtain gas samples from the kiln and the afterburner of an Industrial-scale facility. The samples were analyzed using GC and GC/MS techniques. We include In this communication a report on these preliminary measurements.The United States now generates more than 265 million metric tons of hazardous waste per year. Of this amount, approximately 63 million metric tons are treatable by thermal destruction. 1 Because incineration can, in most cases, literally destroy the organic waste constituents and provide a substantial reduction in waste volume where total destruction is not realized, and because it provides a means for energy and material recovery, it has emerged as a preferred method of treatment.Oppelt has reviewed the state-ofthe-art of incineration techniques. 1 Although most existing hazardous waste incinerators have generally been found to comply with recently imposed federal guidelines, and have for several decades operated with proven performance, there is considerable public skepticism about whether incineration is truly an environmentally benign waste-treatment strategy. An improved understanding of incinerator performance is a necessary prerequisite for more informed public comment on future site location. A better understanding of the chemical and physical phenomena that underlie the operation of existing and currently planned units is also needed for the development of a new generation of incinerators. We have, therefore, initiated a multifaceted experimental and theoretical program directed toward the development of a rudimentary understanding of and predictive capability for rotary kiln and afterburner incinerator performance, as influenced by basic design and operational parameters. Presently, these are related largely through empirical guidelines developed from operational experience. The program we have initiated involves university, industry, and government participation.A series of papers discussing individual components and aspects of this overall kiln study will be presented. This communication is the first of that series. In this paper, we present background information followed by a brief description of the overall program goals and objectives along with our general approach to the problem, including a description of defined subprogram objectives. We conclude this paper with a presentation of preliminary results obtained from one unique sub-program of the experimenta...

“…19 ' 20 ' 24 In many cases, particularly boilers, these ROSEs might be more correctly considered metastable reaction intermediates whose further reaction has been kinetically limited by cooling. Recent studies 20 of a rotary kiln fired with natural gas and being fed liquid CCI4 suggest that blending of product gases to produce an H/Cl ratio greater than unity (about 5.0 during the test) may not have been accomplished in every case. The authors of that study noted spatial nonuniformities of both temperature and composition in the kiln, but attributed the persistence of CC1 4 into the afterburner section solely to the lower temperatures during that test.…”

“…Cundy, et al [1][2][3] have measured the temperature and concentration levels at different locations in a full-scale rotary kiln incinerator burning liquid carbon tetrachloride (CCI4) with a methane/air flame. The sampling locations were at the kiln exit, afterburner exit, and in the stack.…”

“…The leak air locations and flowrates, as well as the heat flux at the kiln walls are varied to study their effects on the kiln operation. A comparison is made with full-scale kiln data [1][2][3], and good qualitative agreement is reached. The issue of grid dependence is addressed but not resolved.…”

A computational modelling study is performed for a full-scale rotary kiln incinerator, using the commercial fluid mechanics code FLUENT. The coordinate system is three-dimensional, and turbulence and buoyancy are also modelled. A global one-step reaction is used for methane combustion. Heat transfer modelling is limited to conduction and convection. The leak air locations and flowrates, as well as the heat flux at the kiln walls are varied to study their effects on the kiln operation. A comparison is made with full-scale kiln data [1][2][3], and good qualitative agreement is reached. The issue of grid dependence is addressed but not resolved.
