The confidence of new technology development for NOx components elimination is obtained as conclusion based like followings; 1) The technology using PSC spark is a excellent methods for NOx components elimention above 70% without by-product pollutants. 2) Some materials like Oxgzen, Vaporized Water and Ammonia, increase the of NOx elimination by staged addition. 3) Enviromental conditions like pulse frequency and peak voltage are the important desing factors for pollutants elimination effects. 4) As the PSC technic is the up-to-date one for pollutions elinilnation the research and development must be executed continuously for the purpose of theoretical establishment. And the application field must be broaden in future.
