    Powder Particle Penetration into Steam-argon Plasma Jet and its Relation with Particle Parameters

  • Original language description

    Interaction of Al2O3 +3% TiO2 particles of diameter in the range 50÷63 ?m with the plasma jet generated by dc arc plasma torch with hybrid water?argon stabilization was experimentally studied. The plasma jet and particles in the feeding region were photographed by a fast shutter CCD?camera. At spraying distance the particle velocities, temperatures, and fluxes were measured by spray diagnostic system DPV?2000. Relationship between the particles injection parameters, the way of penetration into plasma jet, the particle flux, velocities, and temperatures were investigated at different feeding conditions as well as plasma jet properties. The distribution of temperatures and velocities in particle spray have similar character, the particle flux is influenced by carrying air flow rate and the way of injection. The feeding distance has substantial effect on particle velocity, at higher feeding distance the increase of argon flow rate does not increase particle velocity.

    Průnik částic prášku do proudu plazmatu generovaného z vodní páry a argonu a jeho vliv na parametry částic

  • Czech description

    Byla studovaná interakce částic prášku Al2O3 +3% TiO2 v rozsahu velikosti 50÷63 ?m s proudem plazmatu generovaným plazmatronem s hybridní stabilizaci. Volný proud plazmatu a částice v oblasti vstřiku byly fotografovány pomocí rychlostní kamery. Rychlosti, teploty a koncentrace částic byly měřeny diagnostickým zařízením DPV-2000 ve vzdálenosti typické pro provádění nástřiků. Teplota a rychlost částic v oblasti nástřiku máji podobná prostorová rozděleni. Poloha a rychlost vstřiku prášku do proudu plazmatupodstatně ovlivňuje výslednou teplotu a rychlost částic.
