Factors affecting flame propagation through dust clouds 影响火焰通过尘埃云传播的因素

The Malard-Le Chatelier picture of the combustionwave is amended by adding a term for radiant heat transfer. On introducing the rate of oxygen diffusion toward individual particles an expression for the burning velocity in dust clouds is obtained, representing its dependence on thermal conductivity, burning and ignition temperatures, radiation characteristics of the dust cloud, dust concentration and particle size.

This serves as working hypothesis in conductingexperiments on the effect of those factors upon stationary dust flames and flames traveling through quiescent dust clouds.

Results obtained with atomized aluminum are:o

  1. 1.

    On the lean side of the stoichiometric ratiothe burning velocity increases with increasing concentration.

  2. 2.

    The burning velocity increases with decreasingparticle size in the range studied.

  3. 3.

    The failure to produce stationary dust flames with burner tubes smaller than 1/2-inch diameter indicates an effect of “radiation quenching” close to the rim in high temperature dust flames.

  4. 4.

    A striking increase in the flame velocity ofclosed end ignited dust flames is attributed to turbulence.

The experimental results are in qualitative agreementwith theoretical expectations.

马拉德-勒夏特列燃烧波图通过增加辐射传热项而得到修正。通过引入氧向单个粒子扩散的速率，得到了尘埃云中燃烧速度的表达式，表示其与热导率、燃烧和点火温度、尘埃云的辐射特性、粉尘浓度和粒径的关系。这可以作为进行这些因素对静止粉尘火焰和穿过静止粉尘云的火焰的影响的实验的工作假设。雾化铝得到的结果是:1。在化学计量比的偏侧，燃烧速度随浓度的增加而增加。在研究范围内，燃烧速度随粒径的减小而增大。直径小于1/2英寸的燃烧器管不能产生固定的粉尘火焰，这表明在高温粉尘火焰中，在靠近边缘的地方存在“辐射淬火”效应。闭端点燃粉尘火焰火焰速度的显著增加归因于湍流。实验结果与理论预期在定性上是一致的。
