If you're needing that long per iteration check what hardware you're using relative to the cell count. As you add physics you're unlikely to improve the model stability, and additional physics will also put the RAM and cpu load up. 

How is the ammonia added to the burner? Ie is it a droplet spray or do you add gas/vapour to the fuel or oxidant streams?
