  • NH3/CH4/air 予混合気の定容燃焼容器における乱流火炎伝播限界

    In this study, the flame propagation experiments of ammonia/methane/air were conducted using a fan-stirred constant volume vessel in order to clarify the effect of turbulence on the propagation limits of the ammonia/methane/air. Results show that the ammonia/methane/air mixture with a 0.9 equivalence ratio can propagate at the highest turbulence intensity and flames can propagate in larger turbulence Karlovitz number at smaller Markstein number. These tendencies are considered to be due to the diffusional-thermal instability of the flame surface.

  • Experimental study of the turbulent flame propagation behavior of pulverized coal/ammonia co-combustion in an O2/N2 atmosphere within a fan-stirred closed vessel

    This work aims to clarify the spherical turbulent flame propagation behavior of the pulverized coal particle clouds/ammonia co-combustion under different ammonia/oxygen/nitrogen equivalence ratios. Experiments were conducted under various turbulence intensities (u '=0, 0.32, 0.65, 0.97, 1.29 m/s) and in ammonia-lean conditions (ϕ = 0.4, 0.6, 0.8) with a common bituminous coal by using a constant volume spherical chamber. The result indicated propagation velocities of the luminous flame front and the reaction front in co-combustion increased with increasing turbulence intensity. The turbulent flame propagation velocity of the pulverized coal/ammonia co-combustion was higher than that of the pure pulverized coal combustion and that of the pure ammonia combustion under all conditions.

    Ammonia is considered as one of promising energy careers in the future. One of applications using ammonia as fuel is introducing ammonia in coal fired boilers. To realize the utilization of ammonia in coal fired boilers as a fuel, it is necessary to clarify the mixing combustion characteristics of ammonia and coal. In this study, the turbulent spherical flame propagation characteristics of ammonia / coal particle cloud mixture were investigated. Under the various turbulence intensity and the types of coal, the spherical flame propagation experiments were conducted. Experimental results revealed that in some conditions, the flame propagation velocity of the mixture of ammonia / coal particle cloud / oxidizer is higher than that of the mixture of ammonia / oxidizer or that of the mixture of coal particle cloud / oxidizer. This means that there is an interaction mechanism between the ammonia / oxidizer flame and the coal particle cloud / oxidizer flame. The findings from this study can be utilized for establishment of the mixing combustion model of ammonia and coal particle cloud.
