Abstract
A hazardous waste incinerator (100) includes a rotary kiln (120) with a helical flight (250) within. The kiln (120) is fed hazardous waste by either a continuous feed system (164) or a positive feed system (162). The kiln (120) is comprised of six retort sections (202, 202, 204, 206, 208, 210). The combusted waste is separated into ash and recoverable metals. The air flow is counter to the flow of waste through the kiln (120), with exhaust gases vented from the kiln entrance. Fugitive emissions are also contained by shrouds (164, 166) and containment building (160). These exhaust gases pass through the secondary combustor (130) to ensure destruction of any principle organic hazardous constituents. The exhaust gases are then treated in a spray dryer (140) to cool it and neutralize any acidic components. A baghouse (150) then removes any remaining particulate matter before the exhaust exits the stack (156). The control system includes a program-controlled processor unit (400) connected by an optical/electrical interface (402) to an optical data highway loop (404). All parametric sensors of each subsystem is connected to the data loop (404).
