The burning rate emulator (BRE) is a burner that emulates condensed fuel flames using gaseous fuel/inert mixtures by matching four properties: the heat of combustion; the heat of gasification; the laminar smoke point; and the surface temperature. Matching the heat of gasification requires measuring the burner heat flux, for which the BRE has embedded heat flux gauges and a copper top‐plate calorimeter. Seven condensed fuels were emulated: acetone, ethanol, methanol, polyethylene, polymethylmethacrylate, polypropylene, and polystyrene. The gaseous fuels were methane, ethylene, and propylene, diluted with nitrogen. Emulation data and flame images are shown to demonstrate emulation accuracy. A new method of emulation is developed that shifts the focus on which properties are prioritized and yields ~15% improvement in flame height. Calibration and use of the calorimeter are shown to have improved accuracy (within 5%) which provides confidence in the results.

模拟通过多孔铜量热计供应的气态燃料产生的冷凝燃料火焰

燃烧速率仿真器（BRE）是一种燃烧器，它通过匹配四个属性来使用气态燃料/惰性混合物来模拟冷凝的燃料火焰。气化热；层状烟点；和表面温度。要匹配气化热，需要测量燃烧器的热通量，为此BRE内置了热通量计和铜顶板量热计。模拟了七种冷凝燃料：丙酮，乙醇，甲醇，聚乙烯，聚甲基丙烯酸甲酯，聚丙烯和聚苯乙烯。气态燃料是甲烷，乙烯和丙烯，用氮气稀释。显示了仿真数据和火焰图像，以演示仿真准确性。开发了一种新的仿真方法，该方法将重点放在优先考虑属性上，从而使火焰高度提高了约15％。
