Abstract

In order to explore control effect of dynamic pressure caused by depressurization on fire behavior and mechanism on the burn-through ability and enhance fire prevention capability, nearly real emergency dynamic variable pressure environment was constructed, a series of fire resistance tests of oil pools and fire lining were carried out. The results show that depressurization could increase flame height and raise high temperature area, resulting direct contact between flames and cargo compartment ceiling. Cargo liner limited flame height, air entrainment and hot air escape. Raised flame forms jet fire below cargo liner, increased contact area between flame and cargo liners, and enhanced thermal feedback. The decreased mass burning rate led to longer burning time and contact time between flame high temperature area and cargo liner, burned expansion area and carbonized area of cargo liner are larger, and more serious burning damage. © 2021 China Safety Science Journal.
