A DC steam plasma torch includes front, middle and rear sections. The front section includes a first amount and a first electrode attached to the first amount, thus defining co-axial first internal and external coolant channels. The middle section includes a second mount and a second electrode co-axially connected to the second mount, thus defining co-axial second internal and external coolant channels. The rear section includes an insulating transient element connected to the second electrode, a window frame connected to the insulating transient element and a window provided in the window frame. A first swirl generator is provided between the first and second sections to receive primary working gas and generating a swirl in the same. A second swirl generator is provided between the middle and rear sections to receive auxiliary working gas and generating a swirl in the same. |
