ABSTRACT:
A method and apparatus for treating polychlorinated biphenyl contaminated sludge involves heating the sludge, using hot turbulent gas at a temperature in the range of 850.degree. to 2,500.degree. F. with a sludge residence time of about 0.5 to 2 seconds, to separate the polychlorinated biphenyls from the sludge. The particulates are subsequently removed from a PCB entraining gas stream and the PCB's are then burned in a multifuel burner. Pressurized air, fluidized PCB's, and a gaseous fuel are injected into the burning chamber at spaced points along the length of the flame in a direction generally transverse to the direction of the flame to very completely consume the fuel and PCB's.
