A plasma system includes a plasma arc torch, a cylindrical tube and an eductor. The plasma arc torch includes a cylindrical vessel having a first end and a second end, a first tangential inlet/outlet connected to or proximate to the first end, a second tangential inlet/outlet connected to or proximate to the second end, an electrode housing connected to the first end such that a first electrode is (a) aligned with a longitudinal axis of the cylindrical vessel, and (b) extends into the cylindrical vessel, and a hollow electrode nozzle connected to the second end of the cylindrical vessel. The cylindrical tube is attached to the hollow electrode nozzle and aligned with the longitudinal axis, the cylindrical tube having a side inlet and a radio frequency coil disposed around or embedded within the cylindrical tube. The eductor is attached to the cylindrical tube and aligned with the longitudinal axis.
