Modification of electrode of UHF plasma torch to introduce sample aerosol into plasma core.

1 Arc Plasma Torch Modeling

Arc plasma torches are the primary components of various industrial thermal plasma processes involving plasma spraying, metal cutting and welding, thermal plasma CVD, metal melting and remelting, waste treatment and gas production. They are relatively simple devices whose operation implies intricate thermal, chemical, electrical, and fluid dynamics phenomena. Modeling may be used as a means to ...

Application of Microwave Plasma Torch to Power Plant

This presentation is a pure steam-plasma torch generated by microwave energy and uses it for coal gasification in a lightweight operating system. The high temperature of the steam torch when used for fast gasification reactions of low-grade coal ensures a compact reaction system for an electrical power plant.

Dielectric Strontium Zirconate Sprayed by a Plasma Torch

Amultifunctional material, strontium zirconate, SrZrO3, studied in literatures as a dielectric ceramics, thermal barrier coating, proton-conductor, and luminescent material was sprayed by a water-stabilized plasma torch WSP 500. Stainless steel and plain carbon steel were used as substrates. Coatings with thickness of 1 to 2 mm were produced, whereas the substrates were preheated over 450 °C. T...
