“…Numerous devices for thermochemical treatment of MSW have been studied, i.e., mass-burn incinerators (Kilgroe et al, 1990), gasifiers, cyclone reactors (Diebold and Power, 1988). One goal is to reduce the volume of the MSW significantly (about 70-95%).…”

We present experimentally measured devolatilization product yields from single particles of refusederived fuel (RDF), a more uniform, transportable municipal solid waste. Disposal costs and environmental concerns have stimulated interest in thermochemical conversion of this material to chemicals and fuels. The composition, reaction conditions, and particle properties were systematically varied over the range found in practice to develop quantitative measures that rank the process controllables' influence on altering the product slate. Specialized regression methods and experimental designs enhanced the accuracy in view of the feed heterogeneity and offer a general method t o extract real effects from experimental and sample "noise". The results have been verified successfully using actual commercial RDF and fabricated compositions that surpass those normally found in municipal waste to anticipate the influence of trends in recycling. The results show that the reaction conditions have a greater influence on altering fuel utilization and the relative yields of char, condensibles, and gases than does the composition over the range found in MSW and RDF.

“…Pretreatment of MSW to provide somewhat uniform moisture content and composition appears to increase reaction stability and minimize pollutants from combustors (Kilgroe et al, 1990). This has been one rationale behind commercially available densified refuse-derived fuel (d-RDF) (Ishii et al, 1987;Levie, 1988).…”

“…The high particulate concentrations encountered in electrostatic precipitators (ESPs) and fabric filters (FFs) can provide the ideal conditions for dioxin formation [86][87][88]. This is compounded by the fact that operating temperatures are typically within that required for dioxin formation (250-400°C).…”

Dioxin, the collective term for polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans, are generated during various chemical and high temperature processes. They have been shown to be toxic to humans and animals with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exhibiting the greatest toxicity. Dioxin has been shown to exhibit immunotoxicity, reproductive and developmental toxicity in several animals. Epidemiological studies on groups of humans with prolonged or elevated exposure to dioxin have indicated increased cancer rates above threshold levels of exposure. Conversely, other studies have concluded that dioxin is a net anticarcinogen. There has been much study aimed at quantifying the relative contributions of the identified dioxin sources to the environmental load. Although some data suggests that burning of vegetation produces measurable amounts of dioxin it is rather industrial process waste streams which emit the greatest amounts. Processes implicated include organic chemical synthesis, metal processing, paper pulp bleaching and incineration of organic materials. Dioxin emission reduction strategies for high temperature processes have focussed upon the minimisation of the conditions at which dioxin forms in exhaust streams. Additionally, screening of process materials has been practised as have substitution of process chemicals in the pulp and paper bleaching industry.

“…It has been well recognized that equivalence ratio, furnace temperature, residence time, and turbulence mixing are four dominant parameters to achieve stringent destmction demand in incineration process [12,13]. Among these, the former three are relatively easily to measure or control in contrast to the last one -turbulence mixing, in practice.…”

Results of flow visualization studies in a transparent cylindrical chamber are presented to advance the knowledge of three-dimensional flow structure and mixing behavior in rotary kiln incinerators. Reynolds number based on inlet air velocity and diameter of inlet port ranges from 1,700 to 13,700 and covers the laminar, transitional, and turbulent flow regimes. Results show that there are recirculation zones near the inlet corners due to sudden expansion of the chamber. A potential-like core exists in the central and entrance region of the chamber and separates viscous layers near side walls. When Reynolds number exceeds certain critical value, flow instability in the form of large eddies would be generated. These large eddies would break up to smaller eddies in the downstream, and flow becomes turbulent at higher Reynolds number. Small-scale eddies and turbulent motion appear more vigorous when chamber is partly loaded with a bed of solid materials. Effects of size and shape on the movement of single solid material in the rotary kiln are also examined.
