Expert Answer:

Yes, it is true that ammonia is not a supporter of combustion. It extinguishes a burning splint and does not burn in air. It burns only with oxygen with a yellowish-green flame.
When supply so much heat to the ammonia then it absorbed that energy and react with oxygen to give nitrogen and water vapours also heat is produced 
As the reaction is exothermic it exerts heat in the form of flame i.e., yellowish-green flame.
