摘　　要：热表面是一种较常见的点火源,在日常生活、工业生产中普遍存在,可燃液体遇到热表面可能导致火灾、爆炸事故。本文介绍了可燃液体的火灾危险性参数及测定方法标准,试制了一台热表面引燃实验装置,对几种典型植物油进行了热表面的引燃实验,给出了发生50%引燃概率的温度值,分析了热表面最低引燃温度的影响因素。Hot surface is a common ignition source,which exists in daily life and industrial production.Combustible liquid can cause fire and explosion when it meets hot surface.In this paper the fire hazard parameters and standards of determination method of combustible liquid are introduced,a hot surface ignition experimental device is developed,ignition experiments of several typical vegetable oils are carried out,finding out the temperatures of 50%ignition probability.The factors affecting the minimum ignition temperature of hot surface are also analyzed.
