An ammonia decomposition apparatus comprises a casing, a heating zone, a heat exchange zone, a reaction section and a heat exchange coil. The heat exchange coil is spirally wound on an outer wall of the reaction section to efficiently heat ammonia gas. The reaction section has a first reaction zone and a second reaction zone communicated successively, the ammonia gas decomposed into a nitrogen-hydrogen mixture after entering the first reaction zone, with the second reaction zone decomposing for the second time the residual ammonia gas in the nitrogen-hydrogen mixture produced in the first reaction zone, so that the ammonia gas is decomposed more thoroughly. The conversion rate of ammonia gas can reach 99.9% or more, and the residual amount of ammonia gas in the nitrogen-hydrogen mixture can be less than 1000 ppm.
