光纤光栅感温火灾探测器在古建筑中的应用

Application of fiber optic grating thermal fire detector in ancient building

分析楼阁式古建筑的火灾特点,利用FDS对观音阁火灾蔓延情况进行数值模拟,计算特定火灾场景下火灾蔓延过程,得到初期火灾烟气蔓延规律以及温度分布,并在模拟结果的基础上进一步分析光纤光栅感温火灾探测器的设置方法。

The fire characteristics of loft ancient building were analyzed,using FDS,simulation was made on fire spread of Goddess of Mercy Pavilion,the fire parameters was obtained under specific fire scenarios,and the fire spread rules and temperature change were gotten.on the basis of the simulation results,the setting method of fiber optic grating fire detector was further analyzed.
