“…Reactor is built by two chambers. The first one contains the electrodes and there, the highest temperature is reached in the nearest region of the electrodes [11]. The second chamber contains the thermocouple, which senses temperatures up to 425.15 K (it is a lower temperature compared to higher ones reached by thermal plasma [22].)…”

“…Beyond this point, the energy obtained by the supply can no longer sustain the equilibrium phase of the gliding arc, and the electrical conductivity in plasma channel decreases (meanwhile the arc length increases) until the discharge finally extinguishes. Then, a restrike appears, leading to a new periodic cycle [10], [11]. A mobile unit for treating wastes in situ was the study site.…”

This paper describes: 1) the implementation of one system for controlling and monitoring physical variables involved in starting and sustaining a three-phase centrifuged gliding-arc (TPCGA) discharge called gliding centrifugal thermal plasma (GCTP), and 2) the analysis of data collected in spreadsheets by a virtual instrument (VI) to explain plasma behavior. The goal of this work was to program a VI through LabVIEW™ for establishing a central unit to control the performing of the GCTP, and for recording the measurements of the analog signals involved in the process. Data are used to support the analysis and diagnosis steps. In addition, it could also help to propose a closed loop control design, because of the identification of extreme values. Instrumentation also considers the installation of an AC voltage source, gas flow valves, data acquisition cards, and current, pressure, and temperature sensors. For security reasons, a remote interface version of the VI was uploaded to internet. It can be approached when toxic gases are treated.
