Abstract This work documents a series of time-averaged local gas species measurements made throughout the centerline profile of 30 cm methanol, ethanol, and acetone pool fires steadily burning in a quiescent environment. All gas species measurements were obtained using extractive sampling, then analyzed using a gas chromatograph equipped with a mass spectrometer detector (GC/MS). The volume fraction of each species was calculated via the number of moles identified by the GC/MS at each location along the fire's centerline. Soot mass fractions were also measured during the gas-sampling process. The gas species and soot mass fractions were compared at different locations for fires burning three fuels.

中型液池火灾的化学结构

摘要 这项工作记录了在 30 cm 甲醇、乙醇和丙酮池火在静止环境中稳定燃烧的中心线剖面上进行的一系列时间平均局部气体种类测量。所有气体种类测量均使用萃取采样获得，然后使用配备有质谱检测器 (GC/MS) 的气相色谱仪进行分析。每个物种的体积分数是通过 GC/MS 在火灾中心线的每个位置确定的摩尔数计算出来的。在气体采样过程中还测量了烟尘质量分数。对于燃烧三种燃料的火灾，在不同位置比较了气体种类和烟尘质量分数。
