PCB Trial Burn in a Modular, Movable Incinerator

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.
