Material treatment apparatus
Abstract
Abstract Material treatment apparatus comprises a chamber, a plurality of first electrodes having opposed end surfaces adjacent one another to define a passage having an axis passing between the end surfaces. A second electrode structure has its end surface spaced from the first electrodes and aligned with the passage axis. Circuit means energizes the first and second electrodes to produce a high intensity electric arc condition to establish an elongated high enthalpy zone coaxial with said passage axis. Entrance port means in the chamber introduces material to be treated into the zone between the first and seconds electrode structures for flow through the passage defined by the faces of the first electrodes and the high enthalpy zone.
