| Abstract | Rotary kiln systems are widely used in industrial applications to transfer energy from high temperature flames to irregular solids. Recently these systems have been shown to be suitable for the incineration o f hazardous solid waste materials and the thermal treatment o f contaminated soils. Destruction and removal efficiencies in excess o f 99.99% have been reported for hazardous species, but the rate controlling steps o f the incineration process are not well understood. This article describes the design, construction, and operation o f a laboratory scale simulator which was developed to investigate the fundamentals o f hazardous incineration in a rotary kiln environment. This 2 ft X 2 ft refractory-lined kiln allows time-resolved characterization o f contaminant evolution and destruction. Continuous thermal and exhaust concentration measurements are used to characterize the fate o f the solid charge as a function o f residence time within the kiln. Overall destruction efficiency can be measured by subsequent analysis o f the solid phase. The initial performance o f this facility has been demonstrated by studying the combustion o f waste zirconium metal and by characterizing the thermal clean up o f solid sorbent contaminated with toluene. The rotary kiln simulator has been shown suitable for investigation o f parameters such as amount o f charge, contaminate loading, rotation speed, temperature, excess oxygen, and particle size. ’ |
