Show PCB TRIAL BURN IN A MODULAR. MOVABLE INCINERATOR Prakash Acharya ENSCO Environmental Services (ENSCO) White Bluff. TN 37187 ENSCO conducted a trial burn from March 11-13, 1986, in El Dorado. Arkanasas, of an MWP-2000 Modular Incinerations system to destroy PCB liquids, PCB items and PCB-contaminated solids in conformance with TSCA requirements. MWP-2000 has 4 main process modules--Rotary kiln. capable of destroying liquid PCBs and PCB-contaminated dirt: secondary combustor. capable of destroying high-level PCB liquids; heat recovery system, generating steam to drive the system's prime mover; and pollution control system that removes acid gases and fine particulates from the gas stream. The trial burn consisted of 5 separate tests . The first 3 tests were replicate tests. In these tests PCB-contaminated soils, having a PCB content of 1.8%, and PCB-contaminated fuel. having a PCB content of 2.9% were burned in the kiln, while high level PCB liquids having a PCB content of 60%. were burned simultaneously in the , secondary combustor. In the fourth test, PCB liquids. having a PCB,' content of 61%. were burned in the secondary combustor while the kiln was not operated. In the fifth test. pre-shredded capacitors having a PCB content of 18% were fed to the kiln and PCB liquids having a PCB concentration of 64% , were fed to the secondary combustor. Trial burn results clearly demonstrate that a OREs of 99.999999% were achieved. HCl removal efficiencies of 99 .9% were achieved. Total particulate emissions of 0 .01-0.02 gr/DSCF were achieved. PCB contamination in the kiln ash and effluent residuals of <2 ppm were achieved . TRIAL BURN PLAN The demonstration burn plan (trial burn plan) consisted of five separate tests . The first three tests (trial burn #1) were replicate tests! In these tests PCB-contaminated soils. having a PCB content of approxiamtely 5.5%, and PCB-contaminated fuel. having a PCB content of approximately 4.5%. were burned in the rotary kiln (Fig. 1), while high-level PCB liquids, having a PCB content of approximately 46%, were burned simultaneously in the secondary combustor. The purpose of these three tests was to demonstrate the capability of the system to (1) achieve 99.9999% PCB destruction and removal efficiency (DRE); (2) handle solid and liquid wastes in the kiln and liquid wastes in the secondary combustor: (3) remove PCBs from contaminated soils; and (4) produce a scrubber effluent having less than 2 ppm PCB. In the fourth test (trial burn #2), high-level PCB liquids, having a PCB content of approximately 46%, were burned in the secondary -2- |
