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.
