Incineration of Polychlorinated Biphenyl Using a Fludized-Bed Incinerator

摘要

A trial burn of polychlorinated biphenyl (PCB) transformer fluid in a fluidized bed incinerator has been completed at Rocky Flats Plant (RFP). Extensive sampling procedures were used to assess the efficiency of the burn; analysis by Rocky Flats Plant laboratories of the samples collected gave a 99.99992 percent PCB destruction efficiency. This compares well with the independent EPA analysis indicating that 99.9999 percent of the PCB was destroyed. The fluidized bed incinerator utilizes a chromic oxide catalyst to achieve destruction at the relative low operating temperature of 600 exp 0 C and a primary bed of Na sub 2 CO sub 3 to neutralize combustion-generated HCl into NaCl. A low operating temperature permits an all-metal system to be used and the dry off-gas system negates the need of a water or caustic-filled scrubber. (ERA citation 06:035277)
