Experimental Study of Treating Discarded Circuit Boards by Using the Converging - Extended Anode Channel Plasma Torch

In this paper, some discarded circuit boards in the plasma incinerator were incinerated by the converging - extended anode channel plasma torch, whose work principle and composition was described, and two experimental results were described, finally, the percentage of four major exhaust gas (CO, NO, SO2, O2) was reported, showing a good prospect on treating electronic waste with using the plasma torch.
