Experimental study of treating discarded circuit boards by using the converging - extended anode channel plasma torch

摘要

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, SO_2,O_2) was reported, showing a good prospect on treating electronic waste with using the plasma torch.
