Volt–Ampere and Thermal Characteristics of a Direct-Current Dual-Jet Plasma Generator

With the thermal plasma hazardous medical waste treatment as the research background, the volt-ampere and thermal characteristics of a dual-jet direct-current (dc) thermal plasma generator are studied experimentally in this paper. Based on the experimental measurements concerning the arc voltages and thermal efficiencies of the plasma generator under different operating conditions, the generalized dimensional complex equations for the arc voltage and thermal efficiency as functions of the operating parameters are determined with the specified assumptions and by applying the multiple linear regression method to the measured data. The derived generalized functions for the volt-ampere and thermal features are helpful for the design and operation of the dual-jet dc arc thermal plasma generators in actual applications.
