大型储油罐区液池火灾热辐射数值模拟

Simulation on pool fire heat radiation in large scale oil tanks area

以SAFETI软件为工具,研究了大型储油罐区中一个储罐泄漏引发液池火灾后,相邻储罐及周边的热辐射分布及影响。研究表明,10万m3储油罐区中某一隔堤形成池火后,对周边储罐的热辐射值随着罐身位置的升高而升高;在模拟条件下,池火对第一邻近储罐热辐射值为6.76～11.43kW/m2,对第二邻近储罐的热辐射值为3.55～4.70kW/m2,对第三邻近储罐的热辐射值为1.19～1.27kW/m2。并根据热辐射伤害阈值对池火伤害进行了分析。

Pool fire in dike of tanks area was researched to analyze heat radiation and sequence in assumed condition.The results are : the heat radiation value increase from bottom to top on one tank;the heat radiation on closest tank is from 6.76 kW / m 2 to 11.43kW / m 2;the second closest tank is from 3.55 to 4.70kW / m 2,and the third closest is from 1.19kW / m 2 to 1.27kW / m 2.Meanwhile,heat radiation versus distance and the corresponding radiation hurt were researched in this paper.
