Show Establish system with soil mixed soils. stability (combustion and flame pattern) with diesel oil to simulate high BTU Determine the stack particulate emissions from high-chlorine feeds; (200 1b/h equivalent chlorine) vermiculite at 600 1b/hr; and brominated sludge (mixed with soil and sodium sulfate) at 4,000 1b/hr. Perform a trial burn simultaneously with RCRA-regu1ated solids [hexachloroethane (HCE)] and liquids [carbon tetrachloride (CC1 4)] and TSCA-regu1ated polychlorinated biphenyls (PCBs-so11ds and liquids). Verification Tests After the modified system resumed operations, the MIS was required to demonstrate successful particulate emission results at 4,000 1b/hr before normal operations could be continued at this rate. In acrdition, to confirm their previous non hazardous status, de1isting analyses were also required on the four effluent streams namely: kiln ash, cyclone ash, sludge and the process water. A list of de1isting parameters and their regulatory limits are shown in Table 1. Only organic compounds are listed in this table. Analyses were also required for various metals in the effluent streams. The stack particulates during these tests were 0.04 gr/dscf, well below the regulatory limit of 0.08 gr/dscf. All effluent streams (ash solids and scrubber liquid) also met the de1isting requirements. Thus, as a result of these tests, the MIS was permitted to operate at 4,000 1b/hr of dioxin-contaminated solids. All effluents were de1isted, and hence, could be discharged as non-hazardous wastes. Feed Rate Tests It is well known that feed rate limits for a specific incineration system operating at given operating conditions depend upon the feed characteristics. The MIS SCC operating conditions are within those specified by the PCB regulatory requirements. They are also consistent with those previously demonstrated during the dioxin trial burn. For example, the SCC is operated between 2050-2200 0 F with a gas residence time of at least two seconds, etc. Various feed characteristics parameters that affect the feed rate are given in Table 2. A wide variety of feeds were processed by the mobile incinerator during the testing period. A summary of various feed rate tests results is presented in Table 3. With normal, relatively dry (less than 20% moisture) soil, it was quite easy to feed up to 5,000 1b/hr. During the hot summer months, |
