摘　　要：根据家电商场火灾的实际特点,对货架和堆垛两种摆放形式的模拟家电标准组件进行了全尺寸的火灾实验研究.运用实验结果分析了火灾过程中不同阶段的燃烧特点,以及温度、辐射热流和火灾载荷等参数对火灾发展和蔓延规律的影响,并将最高辐射热值拟合为实验关联式,以揭示商场内家电火灾的内在规律和预测其发展趋势.同时获取火灾过程中的基础参数.Based on the actual fire characteristics in home electrical appliances emporium, the full-size fire experimental study was carded out with simulated typical assemblies of home appliances in shelved and piled forms. From experimental results, the barning characteristic in different periods of fire process was analyzed, the effect of parameters such as heat releasing rate, radiating heat flux, and fire load, on fire development and spread was discussed, and an experimental correlation with the top radiating heat flux was obtained to reveal the inherent rule of home appliance fire in emporium and forecast the fire developing trend.
