摘要: 为明确可燃物床层结构特征对燃烧性评价的影响,以南方7种可燃物为例,在3种可燃物床层结构下,采用直接评价法和主成分综合评价法对锥形量热仪结果最大热释放速率(PHRR)、平均有效热含量(AEHC)进行测定研究,结果表明:受床层结构影响,7种可燃物的PHRR与AEHC相关性变差,且对采用PHRR和AEHC的可燃物燃烧性直接评价方法影响较大;不同可燃物床层结构下主成分综合评价方法受影响明显,3种结构条件下秩相关性差,表明基于一种床层结构的锥形量热仪结果,利用主成分综合评价法评价可燃物燃烧性有待进一步深入研究。

Abstract: In order to clarify the influence of combustible bed structure characteristics on combustibility evaluation, taking 7 species in the south China as an example, under the three combustible bed structures, direct evaluation method and principal component comprehensive evaluation method were used to evaluate the results of cone calorimeter, the peak heat release rate and the average effective heat content. The results showed that the correlation between the PHRR and AEHC of the 7 species became worse due to the bed structure. And it has a greater impact on the direct evaluation method of combustibility of combustibles using PHRR and AEHC; the main component comprehensive evaluation method under different combustible bed structures has obvious influence, and the rank correlation is poor under the three structure conditions. It shows that based on the results of a cone calorimeter with a bed structure, the use of the principal component comprehensive evaluation method to evaluate the combustibility of combustibles needs to be further studied.
