摘要： 利用10 MW 大尺度量热计对不同影剧院座椅进行连排燃烧试验研究。建立座椅燃烧试验台，将15 把影剧院座椅分3 排台阶布置，通过对多人影剧院软质座椅排列在一起进行燃烧试验，提供燃烧产生的热释放速率、总热释放量、产烟速率、总产烟量相关特性信息。试验中，分别选取普通影剧院座椅与阻燃影剧院座椅分别进行连排燃烧试验，并将燃烧测试得到的热释放速率、总热释放量等燃烧性能参数进行了对比分析，同时对火焰传播速度进行了计算。结果表明：同样点火方式条件下，普通座椅连排燃烧在8 min 内发生轰燃，热释放速率峰值高达9.204 MW，总热释放量为1 957.2 MJ，经阻燃处理后，热释放速率峰值为83.6kW，总热释放量为27.33 MJ，其他燃烧性能指标均显著下降；普通影剧院座椅连排燃烧时，火焰规模大，火焰扩散速度快，经计算火焰传播速度为0.65 m/min。

Abstract:

A series fire tests of cinema seats that were lined up were carried out in a 10 MW large scale calorimeter. The fire test platform was built. In the test, 15 cinema seats were arranged in three rows steps. Heat release rate, total heat release, smoke production rate, total smoke production were measure through the fire test of cinema row seats. Two group of ordinary cinema seats and two group of flame retardant cinema seats were compared and analyzed, and fire spread rate was calculated based on the teat data. The results indicate that：in the same way of ignition, flashover was happened within 8 min for ordinary cinema seats, the peak HRR and total THR value was 9.204 MW and 1 957.2MJ separately;After flame retardant treatment， the peak HRR and total THR value was decreased to 83.6 kW and 27.33 MJ，other combustion behavior parameters were decreased significantly; Once ordinary cinema seats were ignited, flame spread fast and the flame spread rate was calculated as 0.65 m/min.
