<p>An arc reactor device for producing nitrogen oxides by an arc discharge process includes an electrically conductive casing, defining an arc discharge chamber therein, and an electrically conductive discharge electrode electrically insulated from the casing and extending into the chamber. An arc discharge potential is applied between the discharge electrode and the casing to produce electrical arcing. A starter electrode extends into the chamber and is movable from an extended position in which it contacts the discharge electrode, to a retracted position, in which the starter electrode is out of contact with the discharge electrode. A means for moving the starter electrode from the extended position, at initiation of operation, to the retracted position and maintaining the starter electrode in the retracted position during operation of the arc reactor device includes a solenoid actuator. Air is supplied to the electrically conductive casing from several manifolds which surround the casing. A plurality of orifices extend between manifold chambers, defined by the manifolds, and the discharge chamber with the orifices producing a nonturbulent spiral flow of air in the discharge chamber.</p> |
