Abstract

The paper presents the results of a study of the effect of the flow rate and pressure of a plasma-forming gas (nitrogen) on energy losses in the form of radiation in the chamber of a three-phase plasma torch with refractory electrodes. An increase in energy losses due to radiation over the entire spectral region with increasing pressure is shown. The dependences of the current-voltage characteristics of the discharge, the fraction of radiant losses, and the efficiency of the plasma torch on the nitrogen flow rate and pressure in the chamber are given.

带有末端电极的三相单室等离子炬的传热过程研究

摘要

本文介绍了在带有耐火电极的三相等离子炬室中，等离子体形成气体（氮气）的流量和压力对以辐射形式产生的能量损失的影响的研究结果。示出了由于压力增加而在整个光谱区域上的辐射引起的能量损失的增加。给出了放电的电流-电压特性，辐射损失的比例以及等离子炬效率对室内氮气流量和压力的依赖性。
