摘　　要：实际房间火灾未必全会发生轰燃。本文用山东省2021年全省火灾调查岗位实战比武中按照实际场所再现搭建的软包KTV、城市公寓房间为素材设定火灾场景,对燃烧过程中的温度场、视频数据进行了采集和分析。研究发现:房间火给人员逃生留下的窗口时间仅有90 s左右;火灾后房间的受约束混凝土过梁呈上拱形态;非轰燃房间呈现路径蔓延燃烧状态,温度发展升降起伏,且产烟量大;温度场数据可以作为视频物证的补充来辅助起火部位、过火路径判定。Real room fires may not all lead to flashover. This paper takes room set fire scenarios of soft package KTV and city apartment in Shandong Province’s fire investigation job practical competition in 2021, which were in accordance with the real reproduction, as the object, collected and analyzed the temperature field and video data during the burning process. The study found that: the room fire had a window of escape time only about 90 s;The restrained concrete beams of the room showed an upward arching pattern after the fire;Non flashover room showed travelling fire state, temperature development went up and down, and heavy smoke was produced;Temperature field data can be used as a supplement to video evidence to assist in fire location and fire travelling path identification.
