摘要

利用高功率磁控管产生的915兆赫微波，在常压下产生了大型无极等离子体。与2450-MHz微波相比，915-MHz微波源基于波导诱导等离子体放大。等离子体火焰在内径为80mm的放电管中通过涡流气流维持和稳定。当注入150 l /min的空气作为等离子体形成气体时，在20 kW的功率下，其直径为6.5 cm，长度为130 cm，外观呈火柱状。

Generation of High-Power Torch Plasma by a 915-MHz Microwave System

Large electrodeless plasmas at atmospheric pressure have been generated by making use of 915-MHz microwaves from a magnetron operated at high-power source. In comparison with 2450-MHz microwaves, a 915-MHz microwave source induces enlarged plasma based on waveguide. The plasma flames were sustained and stabilized in a discharge tube with an inner diameter of 80 mm by swirl gas flows. When 150-L/min air as a plasma-forming gas was injected, its diameter and length at an applied power of 20 kW were 6.5 and 130 cm, respectively, displaying a flame pillar in its appearance.
