摘要: 海上平台原油发电机火灾事故产生的高温、热辐射会对邻近设备设施产生不利影响。以某海上平台原油发电机火灾事故为例,运用KFX软件对该火灾过程进行数值模拟,研究了邻近钢支撑、进油软管等关键构件处的温度、热辐射等参数的变化特征。基于温度准则和热辐射准则,研究了温度、热辐射通量临界点变化处时间点与持续时间参数。研究发现,邻近钢支撑2和3表面温度高达1 600 ℃以上,热辐射通量超过25 kW/m2,持续时间长,到达其发生变形与破坏的条件,泡沫释放时间过长造成极大影响。进油软管C处的热辐射强度超过15 kW/m2,到达了其熔化破坏条件,感烟探测器响应时间过长是其主要影响因素。以上研究结果,可为灾后支撑构件强度校核、火气系统响应时间设置等提供参考。

Abstract: The high temperature and thermal radiation generated by fire accident on offshore platforms will have an adverse impact on adjacent equipment and facilities. Based on a crude oil generator fire accident on an offshore platform, this paper numerically simulated the fire process by using KFX software, and studied the variation characteristics of temperature, heat radiation and other parameters near the key components of steel support and oil inlet hose. Based on the temperature criterion and thermal radiation criterion, the time point and duration parameters at the critical point of temperature and thermal radiation flux were studied. It is found that the surface temperature of adjacent steel supports 2 and 3 is more than 1 600 ℃, the heat radiation flux is more than 25 kW / m2, the duration is long, the conditions of deformation and damage are reached, and the long release time of fire-fighting substances cause great impact. The heat radiation intensity at oil inlet hose C exceeds 15 kW / m2, reaching its melting failure condition. The main impact factor is that the response time of fire and gas probe is too long. The research results can provide reference for post disaster support component strength verification, response time design of fine and gas system and so on.
