石蜡火灾扑救过程中的燃烧特性

Research on combustion character during extinguishing of paraffin wax fire

设计制作了由燃烧装置、数据采集处理系统和灭火系统3部分组成的石蜡火灾试验模型,对石蜡火灾扑救过程中的燃烧特性进行试验研究,采集分析了石蜡火灾的热辐射和温度变化数据,描述了火焰燃烧和火焰扑灭过程中的变化趋势。通过实验发现,石蜡并不容易被点燃,流动性是石蜡火灾最重要的特点和危险因素。

An experimental model for simulating the paraffin wax fire was designed and set up, which consists of burning device, data acquisition and processing system and extinguishing system. As a benefit, the tests of the combustion characteristics of paraffin wax were performed in the period of extinguishing. Both the thermal radiation and the temperature variation were acquired and analyzed, as well as the descriptions of their trend in the flame combustion and extinguishing. The experiments showed that the paraffin wax was not easy to be ignited, and the fluidity was the main character and risk of paraffin wax.
