Abstract
Recent trial- and test-burn data from five rotary kiln incinerator facilities were analyzed for combustion performance and metal emissions. The incinerator facilities examined included: DuPont's Gulf Coast Regional Waste Incinerator in Orange, Texas; Chemical Waste Management's Incinerator in Port Arthur, Texas; Rollins Environmental Service's Incinerator in Deer Park, Texas; Martin Marietta's TSCA Incinerator in Oak Ridge, Tennessee; and EPA's Incineration Research Facility in Jefferson, Arkansas. The analysis involved the use of a PC-based computer program capable of performing material and energy balance calculations and predicting equilibrium compositions based on the minimization of system free energy. For each analysis, the feed data of waste and fuel and the corresponding operating parameters associated with incinerator and/or afterburner operation were input to the program and the program simulated the combustion performance under equilibrium conditions. In the analysis, the field-recorded performance data were compared with the simulated equilibrium results and the incinerator performance, including the quality of the field data, the combustion efficiency, the percent excess air, the heat loss, and the amount of air inleakage, was evaluated. In addition, the field-obtained metal data were analyzed for emission rate and metal balance.
