An experimental investigation has been conducted to reduce NO{sub x} in natural gas combustion flue gases by means of corona-discharge-activated ammonia/methane radical injection methods. The multihole-type corona radical injectors are used in the present investigation. Experiments were conducted for the simulated natural gas combustion flue gas (N{sub 2}:O{sub 2}:CO{sub 2}:NO = 83.96:8:8:0.04) flow rate from 1 to 200 L/min, the activation voltage (dc or pulse) from 0 to 40 kV, and the Ar-ammonia or Ar-methane mixture gases flow rate from 0 to 200 mL/min. The results show that the NO{sub x} reduction increases with increasing activation voltage and nonmonotonically depends on ammonia/methane stoichiometry.
