In this work, the effect of discharge condition on the NOx reduction performances by a superimposing barrier discharge plasma reactor is experimentally investigated. The superimposing barrier discharge plasma reactor consists of double coaxial cylinders. The outer tube is made of Pyrex glass with aluminum foil electrode which is the outer electrode. The inner tube is a glass one filled with NaCl solution which is the central electrode, and nickel wire electrode wound on the surface of central electrode is the inner electrode. Amplified AC high voltage is applied to the outer electrode and central electrode, and the inner electrode was used as a common ground. A superimposing discharge is generated by surface or silent discharge of 50Hz and changeable frequency. Experimental investigation has been conducted to reduce NO concentration by two kinds of single discharges operating mode and three kinds of superimposed barrier discharge on the changeable frequency.The results show that the reduction rate of NO at superimposed barrier discharge is higher than that of a single discharge at the same applied voltage. At the range of low discharge power, the highest reduction rate is obtained by silent discharge mode. However, the discharge power is more, the highest reduction rate is obtained by surface discharge mode.
