The antinodal rms pressure fluctuations of a ducted premixed flame has been reduced from 9 to 1.75 kPa by pulsed injection of water with heat removal of less than 3% of the total heat release of 150 kW. A corresponding benefit was the reduction in NO{sub x} emissions from 65 to 30 ppm. Several control strategies were considered and active control based on the oscillation of injection at the same phase as that of the oscillations was found to provide the best combination of attenuation and NO{sub x} reduction.
