摘　　要：介绍了一款新型等离子体炬的结构设计和试验研究情况。在地面试验条件下,低功率非冷却直流等离子体炬能够可靠启动并长时间稳定运行,并在多种燃油、燃气燃烧器中实现可靠点火。试验发现:电流大小和工质气体成分对等离子体炬的电极使用寿命和运行稳定性影响明显。The structural design of a novel plasma torch and its experimental investigation status are introduced. The low-power uncooled plasma torch can start reliably, work with excellent stability for a long time under the condition of ground test, and realize reliable ignition in various gas and oil burners. The investigation result indicates that electric current and gas-flow components can affect service life of the electrode and stability of the plasma torch obviously.
