Comparison of NOx Removal Performance from Simulated Diesel Exhaust Gas by Townsend Type Barrier Discharge and Filamentary Type Barrier Discharge
نویسندگان
چکیده
NOx (Nitrogen Oxides) and PM (Particular Matter) emitted from diesel engines are one of the causes of air pollution. In this research, NOx removal performance from simulated diesel exhaust gas by Townsend type DBD (Dielectric Barrier Discharge) and filamentary type DBD was investigated. As the results, it became apparent that (1) NO concentration decreased with the increase of specific input energy of by both FD (Filamentary Discharge) and APTD (Atmospheric Pressure Townsend Discharge) modes. However, the decrease of NO concentration by APTD mode was lower than that by the FD mode at the same specific input energy. (2) The maximum energy efficiency were 25 g(NO)/kWh in case of FD mode and 16 g(NO)/kWh in case of APTD mode respectively. As a conclusion, the filamentary type DBD is better than the Townsend type DBD to remove NOx.
