アンモニアを燃料とした層流予混合火炎の基礎燃焼特性

抄録

Ammonia is regarded as one of the alternative fuels because of the physical properties of Ammonia are suitable for transportation and storage as the “hydrogen carrier”. On top of those preferable characteristics, the high amount of mass productivity can be achieved through Haber-Bosch process. However, there are some issues of ammonia fuel based on the combustion characteristics to be solved for appling ammonia to the industrial combustion furnaces, such as the low laminar burning velocity, the low flux of radiative heat transfer and also the large amount of Fuel NOx formation. These features of ammonia fuel may lead on the instability of the system operation, and quality of the material in the industrial combustion furnaces. Therefore, it is necessary to know the fundamental characteris of ammonia flame and to find the way how to improve those issues and how to apply ammonia as the fuel in the industrial combustion furnaces. In terms of those requirements, the fundamental characteristics of ammonia/N₂/O₂ laminar premixed flame and the effects of oxygen enrichment were experimentally investigated.
