Abstract :
An experimental investigation has been conducted to reduce NOx from natural gas combustion flue gases by means of corona discharge activated ammonia/methane radical injection methods. The multi-hole type corona radical injectors are used in the present investigation. Experiments are conducted for the simulated natural gas combustion flue gas (N2:O2:CO2:NO=83.96:8:8:0.04) flow rate from 1 to 200 l/min., activation voltage (DC or pulse) from 0 to 40 kV and Ar-ammoniathe or Ar-methane mixture gases flow rate from 0 to 200 ml/min. The results show that the NOx reduction increases with increasing activation voltage and nonmonotonically depends on ammonia/methane stoichiometry
