Radiation power emitted from Ar torch short plasma as a function of in-put power in several kW

摘要: Abstract When the waste would be reduced by arc plasma, radiation power should put down, because it is a great deal of loss. On other hand, we can use as clean source for heating materials in vacuum chamber. In this case, expected that becomes greater. both cases emitted from plasmas has to precisely controlled. We measured plasma torch function electric in-put power. The was 200–700 W an 2–4.4 kW and increased proportion 1.8th current or near 1.6th Therefore, increases steeply with efficiency wall-stabilized model 31% condition 2 cm appearance length, 100 A 4400 An equipment using chamber treatment hazardous wastes due proposed.
