Ammonia radicals were produced in a radical injector using an intermittent one cycle pulsed power source were injected into simulation gas (NO/O_2/N_2). NO was removed efficiently by ammonia radicals which were externally generated by flowing the NH_3 gas diluted with Ar gas through a dielectric barrier discharge (DBD). In order to find optimum parameters for NO reduction and energy efficiency, the reaction temperature, the applied voltage, the NO gas concentration, and the ammonia concentration and flow rate were varied. A maximum energy efficiency of 40g/kWh at a NOx reduction of over 99% is obtained under the optimum condition.
