    1. Thermal plasma production techniques

    There are two main techniques for producing thermal plasmas at or near atmospheric pressure: RF radio frequency torches and direct current (DC) arcs, which are either blown or transferred. The key parameters of plasma production devices are as follows.

    • Thermal efficiency of the torch ρth 

      It quantifies the power dissipated in the gas: Pgaz =ρth×Pρth=PQo/P
