Abstract

Plasma quenching efficiency by ablated vapor of polymers containing nitrogen atom was numerically investigated for the inductively coupled thermal plasma technique. Polyamide66 (PA66), which contains nitrogen atoms, was used for polymer materials, and it is injected into Ar thermal plasma in the numerical simulation. The simulation model considered heating, melting and evaporation of polymer powders, and then plasma quenching phenomena due to polymer ablation. Thermodynamic and transport properties of ablated vapor were also taken into account. It was found that PA66 vapor has a high plasma-quenching efficiency than other polymer materials of PTFE, POM, PMMA and PE. The calculated results were confirmed to be valid comparing with experimental results in terms of ablated vapor distribution and powder velocities.
