Abstract: [eng] [cze]
The ambient air is entrained intensively into atmospheric pressure thermal plasma jets. A system for shielding plasma jet has been used to improve jet characteristics and reduce oxygen content. Different gases have been applied as a shroud gas – argon, acetylene, methane, mixtures of acetylene-nitrogen and hydrogen-nitrogen. All shroud gases used in experiments affected plasma jet making the profiles of the jet characteristics flattened with higher temperatures and velocities and reduced amount of oxygen. Byl studován systém pro ofukování proudu plazmatu stínícím plynem pro zlepšení vlastností proudu plazmatu a omezení oxidace. Bylo použito několik plynů a jejich směsí. Všechny plyny ovlivnily tvar profilů charakteristických veličin proudu, zvýšily rychlost a omezily oxidaci.
