项目摘要

The following were measured : Lean combustion limit and temperature distribution in the combustion tube.On the limit of inflammability it was made that it brought close to the practical level to be a purpose. It was proven that the super lean combustionlimitative curve asymptotically approached usual flammability limit concentration, when the flow rate of the premixed gas increases.And, the lean combustion threshold comcentrstion lowered, when the pre-mixed gas was blown, when the injection mouth was pluralized, and the stable combustion was obtained in the wider region of flow rate.On the measurement of the temperature distribution of the combustion tube inside, the precise and high-speed measurement was abled by development on the combustion tube of diameter of 200mm.The lower end as this result, the upper and has been attcahed to the combustion tube wall on the shape of the flame by the upper part wrapper state, and it is the shape while it opened the combustion tube central part.In additin, that the flame upper end and maximum temperature division exists and that it blows and has connected it to the mouth vicinity and that the flame upper part were accompanied in spite of the position of the upper end in the flame lower end division, and it was proven that the temperature in the upper end division lowers.And there was hardly either the change on the maximum temperature in the flame upper end division as a result under the super lean combustion condition of measuring the tempareture distribution in the stationary burning. When the position and did not change.From then, it was guessed that movement of the position of the flame upper end gave the effect at a super lean combustion threshold concentration.It was clarified that construction of the mechanism teoretical model was necessary without sufficient by showing in sensitivity analysis according to the heat balance model, thiscombustor in the theoretical analysis.
测量了以下内容:研究了稀燃极限和燃烧管内的温度分布,在可燃性极限方面,力求使其接近实用水平。证明了当预混气流量增加时,超贫燃烧极限曲线渐进地接近通常的可燃极限浓度,并且当喷吹预混气时,当喷嘴多元化时,贫燃烧阈值浓度降低。在较宽的流量范围内实现了稳定燃烧。燃烧管温度分布的测量通过对直径200mm的燃烧管的开发,能够进行内部的精密且高速的测量。由此,下端部、上端部以及由上部包覆体状态附着在燃烧管壁上的火焰的形状、以及打开燃烧管中央部时的形状。此外,火焰上端和最高温度分区存在,并且其吹送并将其连接到口部附近,并且火焰上部伴随着不管上端在火焰下端分区中的位置,在超贫燃烧条件下测量稳定燃烧时的温度分布,证明了火焰上端区的温度降低,火焰上端区的最高温度也几乎没有变化。在此基础上,推测火焰上端位置的移动对超贫燃烧阈值浓度产生影响,并根据热平衡模型进行灵敏度分析,阐明了建立机理理论模型的必要性和不充分性。
