Abstract (en)

The invention relates to a method and an apparatus for generating a plasma flame jet. An ultra-high velocity and temperature plasma jet is generated by directly converting fuel gas into a plasma-forming gas. Also various temperatures and velocities of a plasma are provided by combining electrical and thermal energies. The methodes and apparatus of the present invention can be utilized in thermo-treatment, coating, cutting, welding and dehydrating, pulverizing or reducing metals, ceramics or the like, and as a plasma furnace or the like. <IMAGE>
