MICROWAVE PLASMA BURNER

摘要

A microwave plasma burner is disclosed in which a high temperature plasma is generated. The microwave plasma burner includes a wave inducing tube (210) for receiving and guiding microwaves from an antenna (110) of a magnetron (100) within a wave guide resonator (200), so as to generate a high temperature plasma by causing vibrations of an injected gas by the help of the microwaves while discharging the injected gas. The microwave plasma burner according to the present invention gives the following effects. A strong high temperature plasma can be generated with a structure not involving vacuum. The flames are generated by the heat which is generated by the vibrations of air, and therefore, a separate igniting device is not required. High temperature flames are generated, and therefore, the burner of the present invention can be used for welding and cutting. A complete combustion occurs due to the heat which is generated by the vibrations, and therefore, any air pollution can be prevented. A desired gas can be selected, and therefore, any oxidation can be prevented during a welding.
