Abstract Six (6) polymers, 2–6 mm thick, were tested in a cone calorimeter by a standard method at various external heat fluxes (irradiance). The ratio of the effective heat of combustion to the effective heat of gasification per unit mass of volatile fuel, Hc/Hg, also known at the heat release parameter (HRP) or combustibility ratio, was obtained as a sample average for unsteady burning at multiple heat fluxes. Global values of Hc/Hg from unsteady burning are biased by heat flux dependent losses during the test, but are generally within the range of literature values for steady burning. Linearization of the unsteady energy balance provides a parameter (γ) that is the efficiency with which radiant energy is converted to combustion energy. This parameter is in the range, γ = 0.6–0.9, for the polymers of this study.

非稳态燃烧可燃材料的燃烧特性

摘要 六 (6) 种聚合物，2-6 毫米厚，​​在锥形量热仪中通过标准方法在各种外部热通量（辐照度）下进行测试。每单位质量挥发性燃料的有效燃烧热与有效气化热的比值 Hc/Hg，也称为放热参数 (HRP) 或可燃性比，是在多个条件下不稳定燃烧的样本平均值。热通量。来自非稳定燃烧的 Hc/Hg 的全局值受测试期间热通量相关损失的影响，但通常在稳定燃烧的文献值范围内。非稳态能量平衡的线性化提供了一个参数 (γ)，它是辐射能转化为燃烧能的效率。对于本研究的聚合物，该参数在 γ = 0.6-0.9 的范围内。
