Abstract
Experimental results on
energy characteristics of electric-arc plasma generator for heating
technical nitrogen with the power of up to 500 kW are presented.
The features of arc discharge glow, thermal efficiency, and service
life of the electrodes were determined under the regime
of melting the metallurgical raw material in the test plasma
electric furnace.
