Outline of Research at the Start	The control of NOx emission from ultra-lean ammonia-hydrogen flames using a novel strategy targeting N2O emission control will be studied. Efforts will be spent to improve the flame stability, then characterize and control emissions from the flames using numerical simulations and experimentation.
