- 摘要:
- 对LNG泄漏的危害性和池火热辐射的理论模型进行了研究,通过DNVPHAST软件计算，分析了池火火灾热辐射的安全距离影响因素,得到了风速、大气稳定度、泄漏量及围堰尺寸对池火热辐射的影响情况和影响程度。研究发现，风速、泄漏量和围堰尺寸对热辐射的影响范围都有不同程度的影响,其中泄漏量影响最大,而大气稳定度对热辐射的范围影响相对较小。
The harmfulness of the LNG leakage and the theoretical model of the LNG pool fire thermal radiation were studied and the factors affecting the safe distance of the thermal radiation of pool fire were calculated and analyzed by DNVPHAST software. The effect of wind speed, atmospheric stability, leakage and cofferdam size on pool fire thermal radiation were obtained. The research shows that the factors including wind speed, leakage and size of cofferdam all have effects on the range of thermal radiation to varying degree, among which leakage has the most significant effect. The atmospheric stability has relatively less effect on the range of thermal radiation.
