A high concentration NOgas generating system including a circulating path configured by connecting a chamber, a plasma generator, and a circulating means, wherein NOis generated by circulating a gas mixture including nitrogen and oxygen in the circulating path is provided. The high concentration NOgas generating system provides a high concentration NOgenerating system and the high concentration NOgenerating method using the generating system by which NOof high concentration (approximately 500 ppm or above) required for a high level of sterilization process in such as sterilization of medical instruments can be simply and selectively obtained. In addition, since indoor air is used as an ingredient, the management of ingredients is simple and highly safe, and the high concentration of NOcan be simply and selectively prepared on demand.

By focusing on the fact that nitrogen dioxide exhibits an increased sterilizing effect among other sterilant gases including nitrogen oxide, the present invention is made to provide a sterilization method which may be suitably used for sterilizing items to be sterilized such as medical instruments which require increased reliability by using a high concentration NOgas of 5,000 ppm or above, for example. An inside of a sterilizing chamber containing an item to be sterilized is humidified, and a concentration of NOin the sterilizing chamber is made to be from 9 to 100 mg/L by filling a high concentration NOgas.

Systems for generating microwave plasma from a combustion flame. The present invention provides a microwave plasma nozzle that includes a hollow cylindrical housing through which combustible material flows, and a rod-shaped conductor disposed in the housing. A portion of the rod-shaped conductor extends into a microwave cavity to receive microwaves passing in the cavity. The rod-shaped conductor transmits microwaves along the surface thereof, and has a distal end disposed in proximity to and surrounded by a proximal end portion of the housing. During operation, a combustion flame is formed in proximity to the proximal end portion of the housing, and the microwaves transmitted along the surface heat up the flame to generate plasma in proximity to the distal end of the rod-shaped conductor.
