Electric arc stabilized by a vortex of water is used in a special type of plasma torch for generation of thermal plasma jet with extreme plasma parameters. Extremely high plasma enthalpy and plasma temperature and very low plasma density result in very high efficiency of utilization of plasma enthalpy for heating of material injected into plasma. Plasma torches with Gerdien arc are used in industrial scale for plasma spraying, other plasma chemistry applications like waste treatment or gasification of biomass for syngas production are being investigated. Gasification of polyethylene, plastic waste, wooden pellets and saw dust were studied for arc power 100 - 140 kW. Syngas with high content of hydrogen and carbon monoxide and very low content of carbon dioxide was produced.
