Abstract

The torch plasma generated by the plasma torch has the characteristics of high temperature and highly intense radiation. We focused on the radiation that has been ignored as a loss to treat the materials, especially hazardous wastes. The radiation power was 1540 W when the input power was 7000 W and the appearance plasma length was 2 cm at 1 atm. And then, the temperature of the radiation spot concentrated from torch plasma by a lens was measured. The increasing temperature of the radiation spot was 8.2 K. If all the radiation can be focused on the spot, this would lead to thousands of degrees in the temperature rise
