大型储油罐区液池火灾热辐射数值模拟

摘要

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6.76～11.43 kW/m2,对第二邻近储罐的热辐射值为3.55～4.70 kW/m2,对第三邻近储罐的热辐射值为1.19～1.27 kW/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/m2 to 11. 43 kW/m2 ; the second closest tank is from 3. 55 to 4. 70 kW/m2 , and the third closest is from 1. 19 kW/m2 to 1. 27 kW/m2. Meanwhile, heat radiation versus distance and the corresponding radiation hurt were researched in this paper.
