Abstract

A series of experiments are conducted in a 37 cm diameter gas burner situated in a quiescent environment. Time-averaged local measurements of the temperature, velocity, soot, and gaseous species are obtained in 21kW, 34kW, and 50 kW propane fires above the burner centerline. Global measurements of the radiative fraction, flame height, soot and CO yields, and total heat feedback to the burner are also obtained. Time-averaged gaseous species concentrations are measured using a gas chromatograph with mass selectivity and thermal conductivity detectors. The time-averaged soot mass fraction is measured simultaneously via a gravimetric technique. Additional gaseous species and soot measurements are obtained in the exhaust duct via gas analyzers and laser transmission measurements, respectively. A mixture fraction analysis shows that these propane fires exhibit similar trends in which the experimental data nearly matches the idealized state relationships. Carbon monoxide concentrations obtained throughout the fire are presented as a function of mixture fraction and compared among the different propane fire sizes. The dataset provides a comprehensive picture of the mean structure of the three propane fires.

中型丙烷池火灾的表征

在静止环境下，在直径37cm的燃气燃烧器上进行了一系列实验。在燃烧器中心线以上的21kW, 34kW和50kw丙烷火焰中获得温度，速度，烟灰和气体种类的时间平均本地测量值。还获得了辐射分数、火焰高度、烟尘和CO产量以及向燃烧器反馈的总热量的全局测量。时间平均气体种类浓度测量使用气相色谱仪与质量选择性和热导检测器。时间平均烟灰质量分数是通过重量测量技术同时测量的。通过气体分析仪和激光透射测量分别在排气管道中获得额外的气体种类和烟尘测量。混合分数分析表明，这些丙烷火灾表现出相似的趋势，实验数据几乎与理想状态关系相匹配。在整个火灾过程中获得的一氧化碳浓度以混合物分数的函数表示，并在不同丙烷火灾规模之间进行比较。该数据集提供了三次丙烷火灾平均结构的全面图像。

期刊介绍： Fire Technology publishes original contributions, both theoretical and empirical, that contribute to the solution of problems in fire safety science and engineering. It is the leading journal in the field, publishing applied research dealing with the full range of actual and potential fire hazards facing humans and the environment. It covers the entire domain of fire safety science and engineering problems relevant in industrial, operational, cultural, and environmental applications, including modeling, testing, detection, suppression, human behavior, wildfires, structures, and risk analysis. The aim of Fire Technology is to push forward the frontiers of knowledge and technology by encouraging interdisciplinary communication of significant technical developments in fire protection and subjects of scientific interest to the fire protection community at large. It is published in conjunction with the National Fire Protection Association (NFPA) and the Society of Fire Protection Engineers (SFPE). The mission of NFPA is to help save lives and reduce loss with information, knowledge, and passion. The mission of SFPE is advancing the science and practice of fire protection engineering internationally.
