Abstract

In order to improve ISB cleaning up efficiency of spilled oil on water，a cruciform plate device was designed to improve BE of oil spill fire based on mechanism of external device's enhancement of flame's heat feedback on oil layer. Then，influences of cruciform plates' height on fire characteristics of spilled oil under different oil pool diameters were studied through a series of experiments. The results show that when plate height is smaller than diameter of oil pool，cruciform plate cannot help improve combustion efficiency. And as its height increases，it receives a large amount of flame heat and transfers that to oil layer，thus improving burning rate and efficiency of pool fire. When the height is at a ratio of 1∶2 with pool diameter，BE will reach its maximum value. But while device height continues to rise，it increases heat dissipation of oil pool to air，which instead reduces BE. © 2020 China Safety Science Journal. All rights reserved.
