The effect of ac applied voltage phase differences on the NO{sub x} reduction from the combustion flue gases by superimposed surface and silent discharge plasma reactor is experimentally investigated. The experiments are conducted for the applied voltages from 0 to 24 kV, the flue rates from 0.5 to 2 L/min, the ammonia mixture concentration from 0.7 to 1.2 stoichiometry, and the applied phase differences from 0 to 180 degrees, where two 60 Hz ac power supplies are used. The results show that: (1) NO{sub x} reduction rate increases with increasing discharge power, gas flow rate and ammonia stoichiometry for in-phase operations; (2) NO{sub x} reduction rate for out-of-phase operations is much higher compared with in-phase operations. However, NO{sub x} reduction rate has an optimum condition on ammonia stoichiometry, discharge power and gas flow rate; (3) Energy efficiency of NO{sub x} reduction increases with increasing ammonia mixture and gas flow rate, and decreases with increasing discharge power; (4) Energy efficiency of NO{sub x} reduction under out-of-phase operations is much larger compared with in-phase operations.
