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).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
