Propane Oxidation in a Plasma Torch of a Low-Current Nonsteady-State Plasmatron 在有低电流非稳态等离子体The electrode system of plasmatron outwardly resembles that for classical arc plasmatron, which is powered from dc voltage V0. However, the average discharge current is limited by a ballastresistorR atalevelof0.2A.With such a low current,the steady-state arc is not able to be sustained so that the discharge burns in a specific nonsteady-state regime. This is the reason why we refer to our device as a nonsteady-state plasmatron 等离子体发生器的电极系统类似于经典的电弧等离子体发生器向外，这是从直流电压V0供电。然而，平均放电电流是由一个镇流电阻器让i=0.2A控制有限。这样低的电流，稳态电弧是无法持续的以至于放电燃烧用一个特定的方法非稳态方法。这就是为什么我们把设备作为一个非稳态等离子体发生器 IEEE TRANSACTIONS ON PLASMA SCIENCE, VOL. 40, NO. 2, FEBRUARY 2012 （IEEE等离子体科学，40卷，2号，2012二月） 等离子体火炬（亦称等离子体发生器或等离子体加热系统）就是依据这一原理研制的专门设备。等离子体火炬通过电弧来产生高温气体，可在氧化、还原或惰性环境下工作，可以为气化、裂解、反应、熔融和冶炼等各种功能的工业炉提供热源 Abstract—This paper describes the plasma-assisted combustion system intended to generate a torch flame with a high power density per unit area. In the system, a kind of hybrid concept is proposed. A primary unit for combustion sustaining is a low-current nonsteady-state plasmatron with a low level of electric power. The plasmatron activates an air/hydrocarbon mixture and sustains the oxidation processes in the plasma torch. In turn, the heat power of the torch sustains the main burning process in the torch flame. The results of experiments on propane oxidation in the plasma torch of plasmatron in a wide range of equivalence ratio are presented. As applied to the combustion system design, the plasma torch can provide both the complete and the partial propane oxidation with syngas generation. 摘要:本文介绍了等离子体辅助燃烧系统来产生每单位面积的高功率密度火炬的火焰。在该系统中，提出了一种混合动力概念。燃烧持续的基本单元是一个有低功率的低电流非稳态等离子体发生器。在等离子体炬中等离子发生器激活空气/烃混合物和维持氧化进程。相应的，火炬的热能维持在等离子体炬火焰主要燃烧过程。在含等离子发生器的等离子炬的丙烷氧化实验结果中许多的等值比被提出。适用于燃烧系统设计，等离子炬能让完整的和含合成气的部分丙烷氧化。 等离子体发生器：用人工方法获得等离子体的装置CONSIDERABLE interest has recently been generated in atmospheric-pressure low-current discharges in a ga
