Abstract

Bed mattresses are rated as products to cause a fire hazard because of their very high heat release rate among indoor combustibles. In this study, fire growth rate and flame height were measured through a series of combustion experiments on a full scale in order to provide information regarding mattress fire characteristics. The experiments were conducted in an open space, and bed mattresses as the test samples were installed at different installation heights (0~515 mm). The experiment results revealed that the higher the bed mattress was installed, the higher the fire growth rate, the heat release rate, and the flame height. Additionally, the time of the mattress to reach 1 MW was evaluated as the category "medium" in the NFPA 72 standards. The flame heights showed a good coincidence compared to the existing flame height model equations, proving the applicability of the model to the mattress combustion.

摘要

床垫因其在室内可燃物中极高的热释放率而被列为会引发火灾危险的产品。在本研究中，通过一系列全尺寸燃烧实验测量了火灾增长速率和火焰高度，以便提供有关床垫火灾特性的信息。实验在露天空间进行，将床垫作为测试样本安装在不同的安装高度（0至515毫米）。实验结果表明，床垫安装得越高，火灾增长速率、热释放率和火焰高度就越高。此外，床垫达到1兆瓦的时间在NFPA 72标准中被评估为“中等”类别。与现有的火焰高度模型方程相比，火焰高度显示出良好的一致性，证明了该模型对床垫燃烧的适用性。
