摘要

已知传统的线性直流等离子体火炬具有相对较长的尾焰,其中可以进行高温化学反应或等离子体可以作为传热介质。将固体颗粒引入这些等离子体火炬通常会使等离子体不稳定,并可能对阳极造成广泛的侵蚀,从而大大缩短火炬的工作时间。在这种火炬固体颗粒暴露在电弧温度,而不仅仅是尾焰温度。这种火炬使人们能够在非常接近等离子弧的地方引入固体粒子,如果粒子速度优化,粒子甚至可以穿透电弧。本文介绍了一种v型等离子体系统的设计和典型工作参数,并讨论了该系统的优缺点。

A thermal non-transfer arc V-type torch plasma
Conventional linear DC plasma torches are known to have a relative long tail flame wherein a high temperature chemical reaction can be performed or where the plasma can act as a heat transfer medium. Introducing solid particles into these plasma torches generally destabilizes the plasma and may cause extensive erosion on the anode, thus shortening the torch operational time significantly. In this torch the solid particles are exposed to the arc temperature and not only the tail flame temperature. This torch enables one to introduce solid particles in very close proximity of the plasma arc and if the particle velocity is optimized, the particles may even penetrate the arc. This paper presents the design and typical operating parameters of a V-type plasma system, and discuses the advantages and disadvantages of such a system.
