Abstract
When a reduction of waste and dissolution of iron are carried out by using arc plasma, we need to suppress the arc radiation power, because there are some cases of damaging the furnace wall due to the radiation. In those cases the radiation power from plasma has to be precisely controlled.<br>However there are few reports on the radiation power from the torch plasma in the past day. So, we tried to measure the radiation power from torch plasma using a power-meter. The radiation power was measured to be about 600 W for an appearance plasma length of 20 mm at 100 A and increases in proportion to the 1.8th power of current.<br>The radiation efficiency will be 34% in the condition mentioned above in the sphere model. Furthermore, the radiation efficiency for the whole plasma due to wall-stabilized arc model is 27%, and also the radiation efficiency for the torch plasma is 15%.
