Abstract

The present invention is a plasma jet generating apparatus that includes a cathode module having a cathode, an anode module having a first passage therethrough and an intermediate module positioned between the cathode and the anode module. The intermediate module includes at least one insert electrically isolated from the anode and cathode modules and defining a second passage in fluid communication between the cathode and the first passage. The first passage can initially converge and then, optionally, diverge in a direction away from the intermediate module. Also or alternatively, the second passage can optionally diverge in a direction toward the anode module. A pilot insert can be positioned between the anode module and the interelectrode insert for the purpose of initiating an electrical arc. A feeding module can be positioned to feed material adjacent the end of the anode module opposite the intermediate module for treatment by the plasma jet.
