  • Decomposition processing apparatus for PCB
    Patent number: 6619217
    Abstract: A decomposition processing apparatus for PCBs prolongs the staying time of the PCBs in a vertical furnace. The apparatus heats and decomposes the PCBs and includes porous staying plates through which the falling PCBs pass, to delay the progress of the PCBs through the apparatus and thus subject the PCBs to sufficient thermolysis.

  • Decomposition processing apparatus for PCB
    Publication number: 20020110506
    Abstract: A decomposition processing apparatus 1 for PCB prolongs a staying time of PCB even in a vertical furnace or the like. In the decomposition processing apparatus 1 for PCB which heats and decomposes supplied PCB 2, staying means 3 which has the affinity to PCB 2 is provided so as to guide PCB 2 and obtain a staying time during which PCB 2 is satisfactorily subjected to thermolysis.
