OPERATIONAL PARAMETERS OF THERMAL WATER VAPOR PLASMA TORCH AND DIAGNOSTICS OF GENERATED PLASMA JET

摘要

The operational characteristics of the experimental direct current plasma torch with water vapor stabilization of the arc discharge and diagnostics of generated plasma jet at the nozzle exhaust of the torch were studied in this research. The operation parameters of the torch are presented in terms of generalized thermal and electrical characteristics, which were compared with equations for steam plasma generators. Optical emission spectroscopy (OES) method was used as an important diagnostic tool to investigate the composition of generated plasma jet. The rotational and excitation temperatures of species from the emission spectra were calculated roughly.
