Gas-dynamic and thermal processes in a high-frequency induction plasma torch with tangential stabilization of the gas flow

详细

The gas-dynamic and heat-exchange processes in a coaxial type plasma torch with tangential stabilization of the gas flow and a central inlet for feeding the raw material into the high-temperature region of plasma at atmospheric pressure were studied. The temperature range in the high-temperature zone (3500–4000 K) and near the plasma torch walls (930–1400 K) and the residence time of the reaction mixture in the high-temperature zone were estimated. The peculiarities of the gas flow motion using a feed probe were considered. The results, in comparison with the experimental operating modes of the plasma torch, make it possible to proceed to the construction of a plasma torch of higher productivity.
