摘要

与有焰火火灾相比，阴燃及其引起的火灾在实验和理论方面的研究较少，尤其是开敞室内空间全尺寸阴燃实验研究比较缺乏。该文基于ISO9705燃烧室自制的阴燃试验台，开展多孔可燃材料（聚氨酯软泡）阴燃实验，分析聚氨酯软泡在不同的热流强度条件下引燃温度和升温速率的变化规律，得到聚氨酯软泡在开敞条件下阴燃点燃过程中的化学变化过程和临界点燃温度。

Abstract

Theoretical and experimental research on fire caused by smoldering reaction is insufficient in contrast with that on flame combustion. Especially the fullscale experimental study of smoldering combustion of porious combustible materical in open room is scarce. Based on experiments of cellular combustible material

polyurethane

on a selfmade testbed in an ISO9705 fire room

the change trends on both ignition temperature and heating rate are analyzed under different initial heating flux. Further

the chemical reaction and supercritical temperature of smoldering ignition in open space are obtained and analyzed during the research.
