Zusammenfassung:	To stabilize an ignition position and suppress NOx generation in an ammonia combustion burner and a boiler.SOLUTION: An ammonia combustion burner related to at least one embodiment of this disclosure is an ammonia combustion burner for burning ammonia fuel by using a boiler, and includes: an ammonia injection nozzle for injecting ammonia fuel; a combustion air nozzle for ejecting combustion air from the outer side of the ammonia injection nozzle; and a flow speed distribution provision part for providing the combustion air ejected from the combustion air nozzle with flow speed distribution.SELECTED DRAWING: Figure 3 【課題】アンモニア燃焼バーナ及びボイラにおいて、着火位置の安定化やＮＯｘの発生の抑制を図る。【解決手段】本開示の少なくとも一実施形態に係るアンモニア燃焼バーナは、ボイラでアンモニア燃料を燃焼させるためのアンモニア燃焼バーナであって、アンモニア燃料を噴射するためのアンモニア噴射ノズルと、アンモニア噴射ノズルの外側から燃焼用空気を噴出するための燃焼用空気ノズルと、燃焼用空気ノズルから噴出される燃焼用空気に流速分布を付与する流速分布付与部と、を備える。【選択図】図３
