| Abstract: | On a double-jet plasmatron with cylindrical single-chamber electrode units, an experimental study of volt-ampere characteristics
of the electric arc is conducted at current 105–550 A, voltage 400–1320 V, total flow rate of the plasma-forming gas (air)
(0.76–9.83)∙10−3 kg ⁄ s, angle between the cathode and anode parts 45–62°, distance between the cathode and anode axes at the outlet from
nozzles 0.07–0.2 m, and outlet pressure of ~0.1 MPa. Correlations for these characteristics are obtained. |
