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).

Hazardous waste incinerator and control system

Linear ignition tube suitable for the ignition of long propellant beds. The tube comprises an elongated tubular member having a ratio of interior diameter to wall thickness of at least 4. The ignition tube is provided with a plurality of ignition strands formed of an oxidizable ignition material at a density of at least 2 strands/0.001 in.sup.2 of a cross-sectional area of the tubular member. The ignition strands provide a linear ignition rate for the tube within the range of 3000-6000 ft/sec. The tube can contain from 30-50 ignition strands formed of a self-oxidizing ignition material such as nitrocellulose fibers coated with a mixture of an oxidizing component such as a mixture of ammonium perchlorate and a fuel component such as aluminum. An ignition transmission system comprises a plurality of ignition tubes which extend in a longitudinal conjoint relationship in which one tubular member at least overlaps partially another. The walls of the tubular members are sufficiently thin so that, upon ignition of the ignition strands within one tubular member, communication of the ignition reaction from the first tubular member is transmitted to the ignition strands of the other tubular member. The ignition system is useful in elongated propellant charges such as ordnance cartridges.
