Arcs, plasma torches and applications

IEEE Conference Record - Abstracts. 2002 IEEE International Conference on Plasma Science (Cat. No.02CH37340), 2003
Summary form only given, as follows. The applications of arcs and plasma torches can be roughly classified in two domains: electrical engineering and thermal (or chemical) processes. In the first category we can consider circuit-breakers, arc lamps and some aspects concerning lightning. In the second category, we can distinguish metallurgical processes

The RF Plasma Torches

2016
The basis of the physical processes in the RF plasma torches and parameters of the RF plasma torches will be considered in this chapter. They are based on the two models—equilibrium and nonequilibrium plasmas, as well as the experimental results.

Inductively Coupled Plasma Torches

2013
We investigate in this chapter another type of application using eddy currents. An Inductively Coupled Plasma torch (commonly referred to as ICP) is a technical device used to analyze a given sample (gas, solid or liquid prepared as an aerosol) by injecting it in a plasma (generally made of argon) (see Fig. 10.1).

Electrode erosion in plasma torches

Plasma Chemistry and Plasma Processing, 1992
Cathode erosion rates are reported (or copper electrodes in a simulated plasma torch operating at atmospheric pressure. The are current was 100A (or most experiments; the magnetic field used to move the arc varied between 0.001 and 0.15 T. Different plasma gases were used (Ar, He, air, N2, CO, and mixtures of the noble gases with O2, N2, CO, CH4, Cl2 ...

Diagnostics of a DC plasma torch

SPIE Proceedings, 1991
Optical emission spectroscopy, Langmuir probes, and calorimetric techniques have been used to characterize the plasma jet in a DC plasma torch diamond deposition apparatus. The experimental data are compared to calculations based on a thermodynamic equilibrium model.

Supersonic Flow Ignition by Plasma Torch and H2/O2 Torch

Journal of Propulsion and Power, 2004
The effectiveness of an H 2 /O 2 torch igniter, which injects H 2 /O 2 combustion gas, and a plasma torch igniter in promoting ignition of an H 2 /air mixture within a supersonic combustor was investigated analytically and experimentally. First, bulk temperature and bulk radical concentration in an O 2 plasma torch igniter were estimated by ...

Arc plasma jets of a nontransferred plasma torch

IEEE Transactions on Plasma Science, 1996
The plasma flow of a nontransferred plasma torch used for thermal plasma processings is produced by the arc-gas interactions between a cathode tip and an anode nozzle and expands as a jet through the nozzle. In this work, numerically calculated images of the are plasma characteristics are found over the entire plasma region, including both an arc-gas ...

Induction-Coupled Plasma Torch

Journal of Applied Physics, 1961
A new method of generating a stable plasma at atmospheric pressure using inductive coupling at a frequency of several Mc is described. Methods of starting and operating this plasma in argon, and mixtures of argon with helium, hydrogen, oxygen, and air are discussed.
