Abstract

In a method and system for the combustion of ammonia, wherein a first combustion chamber receives ammonia and hydrogen in controlled proportions, and an oxygen-containing gas such as air. Combustion of the ammonia and hydrogen produces nitrogen oxides among other combustion products. A second combustion chamber receives the nitrogen oxides along with further ammonia and hydrogen in further controlled proportions along with further oxygen-containing gas such as air. The nitrogen oxides are combusted into nitrogen and water.
