Abstract

Provided are an apparatus for normal pressure plasma ignition and a method for normal pressure plasma ignition using the same. The apparatus for normal pressure plasma ignition of the present invention comprises a wave guide tube wherein microwaves are applied, a dielectric tube that penetrates said wave guide tube and introduces a reactant gas, and an ignition apparatus for normal pressure plasma wherein microwaves are applied in said dielectric tube to turn said reactant gas into plasma, wherein said ignition apparatus penetrates said dielectric tube and includes an ignition rod that emits thermal electrons as said microwaves are applied in said dielectric tube. The apparatus for normal pressure plasma ignition according to the present invention enables ignition to be accomplished without power, so that the problems with the prior art that requires high voltage (excessive power, stability issues) may be avoided at the same time. In addition, the normal pressure plasma ignition apparatus according to the present invention enables movement of the ignition rod inside and outside its dielectric tube so that physical damage to the ignition apparatus due to plasma heat may be prevented, and also affords the effect that the scope of metallic materials used in the ignition apparatus is significantly wider than that of the prior art.
