摘要
采用自行设计与建成的试验平台进行火灾时无喷淋作用下密闭、自然通风和机械排风三种情况的实验.结果表明,室内火灾的烟气在传播过程中,不同高度烟气温度的分布规律是较高处的升温速度及温度均比低处的稍高,排烟强度是决定烟气温度的主要影响因素.
Having experiments by test platform which was designed and builted by ourselves in these three conditions： airtight without spraying,natural draught,both of natural ventilation and mechanical exhaust.The results showed that： the distribution regularity of smoke distribution in the process of transmission of fire smoke indoor is that both of the speed of gas temperature rise and the gas temperature in the high level are a little higher than the speed and temperature in the low level,so the strength of discharge is the major factor deciding the temperature of fire smoke.
