VERFAHREN UND VORRICHTUNG FUER DIE BEHANDLUNG VON DURCH POLYCHLORIERTE BIPHENYLEN VERUNREINIGTEN SCHLAEMMEN.

摘要

A method and apparatus for treating polychlorinated biphenyl contaminated sludge involves heating the sludge (14) using hot turbulent gas at a temperature in the range of 850 DEG to 2,500 DEG F. with a sludge residence time of about .5 to 2 seconds, to separate the polychlorinated biphenyls from the sludge. The particulates are subsequently removed from a PCB entraining gas stream (16, 18) and the PCB's are then burned in a multi-fuel burner (20). 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.
