Thermal Plasma Generators with Water Stabilized Arc

Thermal Plasma Generators with Water Stabilized Arc

Electric arc stabilized by a vortex of liquid, mostly water, is used in a special type of plasma torch for generation of thermal plasma jet with extreme plasma parameters. The paper presents analysis of properties and processes of water stabilized arcs and discusses differences from common gas stabilized arcs. Plasma torch utilizing stabilization of arc column by combination of gas flow and liq...

Non-thermal Arc Plasma for Ethanol Reforming and Hydrogen Production

Non-thermal plasma, also called non equilibrium arc plasma, is a kind of low temperature plasma. Thermal arc plasma is usually driven by a high power supply and characterized by a high current (several amperes to tens of amperes) and a small low voltage (tens of voltage). It is a kind of strongly self-sustaining high-temperature discharge. Unlike thermal plasma, non-thermal arc plasma is usuall...

Effect of Arc-anode Attachment on Thermal Plasma Jet

An interaction of plasma flow with an arc-anode attachment in a dc arc plasma torch was investigated. Statistical processing of the photographic images of plasma jet was used for analysis of an effect of the anode attachment on structure and stability of plasma flow. Deflection, flattening and flutter of the plasma jet was found to be caused by disturbing effect of the arc-anode attachment.

Combustion Enhancement via Stabilized Piecewise Nonequilibrium Gliding Arc Plasma Discharge (postprint)

A comparative numerical study of hybrid-stabilized argon-water electric arc

The so-called hybrid stabilized electric arc utilizes a combination of gas and vortex stabilization. In the hybrid argon-water plasma torch, the arc chamber is divided into the short cathode part, where the arc is stabilized by tangential argon flow, and the longer part, which is stabilized by water vortex. This arrangement provides not only the additional stabilization of the cathode region an...
