A new experimental technique for investigation of plasma generated with plasmotrons in electrophysical installations
Résumé
A new experimental technique for investigating characteristics of plasma generated with plasmotrons in electrophysical installations was proposed. The technique involves a simultaneous registration of both radiation spectra and images of plasma and consequent analysis of the registered data [1]. The experimental technique proposed permits to acquire much more information about plasma characteristics compared to common techniques of separate registration of spectra and images and reveal possible correlation between spectral parameters and image features of plasma [2]. The technique proposed was experimentally realized using complex of apparatus fulfilling simultaneous registration of both radiation spectra and images of plasma generated in electrophysical installations designed for destruction of hazardous and harmful substances [3]. Analysis of the data acquired using the proposed technique permits to find both optimum operating conditions of existing plasmochemical reactors and the optimum number and spatial arrangement of plasmotrons in reactors being designed. Optimization here means attaining maximum effectiveness of destruction of the substances, increasing destruction speed, reducing consumption of electric power and consumable chemicals, and a whole number of the other positive results. It is also possible to use output signals of the registering apparatus to control plasmotrons'operating conditions in real time i.e. to build plasmochemical reactor with feedback.
