项目摘要
In this fiscal year, research was smoothly progressed.First, experiments on turbulent flame propagation and extinction on pure ammonia combustion and particle cloud/ammonia co-combustion were separately conducted.Second, comparison between pure ammonia combustion and co-combustion was finished. It was found that volatile matters from particles have an important effect on turbulent flame propagation and extinction of co-combustion. When ammonia equivalence ratio is lower than unity, the volatile matter enhances flame stability. However, in ammonia rich cases, it has negative effect.Third, turbulent flame propagation and extinction mechanisms were proposed to understand the phenomena.
本财政年度,科研工作进展顺利。首先,分别进行了纯氨燃烧和颗粒云/氨共燃烧湍流火焰的传播与熄灭实验。其次,对纯氨燃烧和共燃烧进行了比较。研究发现,颗粒中的挥发物对共燃烧湍流火焰的传播和熄灭有重要影响。当氨当量比小于1时,挥发分的火焰稳定性增强。然而,在氨丰富的情况下,它有负面影响。第三,提出了紊流火焰的传播和熄灭机制来理解这一现象。
