摘　　要：利用自行设计的流淌火实验装置开展可膨胀石墨粉抑制原油流淌火的模拟实验,研究了可膨胀石墨粉喷射强度对流淌火的火焰热辐射、油品质量损失速率和石墨粉的膨胀覆盖厚度的影响,并对其抑制油火的机理进行理论分析。实验表明,可膨胀石墨粉具有较好的抑制原油流淌火的作用,喷射强度越大,抑制作用越强;石墨粉受热膨胀在油品表面形成一层致密的隔热覆盖层是抑制原油流淌火的主要原因。The effect of discharge rate of expandable graphite powders on the thermal radiation and the mass loss rate of crude oil flowing fire and the covering thickness of expanded graphite powders were studied using self-designed experimental platform, and the mechanism of crude oil flowing fire suppression by expandable graphite powders was analyzed. The results indi- cate that the expandable graphite powders has good effect for suppressing crude oil flowing fire, and the effect increases with increasing the discharge rate, and the main reason for fire suppression is the formation of the dense covering layer of expand- ed graphite powders on the oil surface.
