METHOD FOR REMOVING NITROGEN OXIDE BY USING OZONE AND AMMONIA

摘要

PURPOSE: A method for removing a nitrogen oxide is provided to remove the nitrogen oxide by inducing an oxidation of NO with injecting the ozone as oxidizer into exhaust gas and making a nitric acid chloride using the ammonia at the same time, and to reduce the operating power. CONSTITUTION: Nitrogene is oxidized by injecting an ozone generated in a generating device of the ozone the same as the concentration of NO needed to be converted into exhaust gas in the ratio of 1: 1 to process a nitric acid chloride of exhaust gas using the ozone and the ammonia. And the NOx(NO+NO2) is reduced by reacting with injecting the ammonia into the NO2 generated by oxidizing with the ozone in the range of 0.6 - 1.0.
