Thermal and power characteristics of plasma torch with reverse vortex

Resumo

The results of experimental investigations of electrical and thermal characteristics of a vortex plasma torch with a reverse vortex, generated in a hollow blind-end electrode, are presented. It is shown that the reverse vortex essentially improves the performance of the plasma torch and contributes to an increase in the thermal efficiency and enthalpy of the plasma jet. © 2009 IOP Publishing Ltd.
