摘要:
为研究大型储油罐区池火灾温度、热辐射强度、流速、组分等燃烧特性参数在油罐外不同区域的变化规律,以10万m3原油储罐区为研究对象,构建罐区池火灾燃烧数学模型,运用计算流体动力学(Computational Fluid Dynamics,CFD)技术进行数值模拟研究。结果表明:整个火场温度大致呈锥形分布,火焰温度最高可达1 500 K,纵向来看,底部温度较高,上部温度逐渐降低,径向来看,中心温度较高,周围温度逐渐降低;随着距罐壁以及距罐顶距离的不断增加,热辐射强度均呈现逐渐降低的趋势,最高热辐射强度为132 kW/m2;罐顶上方区域存在火焰卷吸现象,中心位置流速最大,最高可达56 m/s,罐底区域存在火焰贴壁现象;得到燃烧产物(CO和CO2)的体积分数分布,以CO体积分数为0.001作为判断依据,推断出火焰高度为120 m。研究结果可为今后此类火灾事故的防治提供理论支撑。
Abstract:
In order to study the change rules of combustion characteristic parameters such as the temperature,heat radiation intensity,flow rate and components in different areas outside the oil tank,the 100 000 m3 crude oil tank farm was taken as the research object.A mathematical model of pool fire combustion in the tank farm was constructed,and the computational fluid dynamics (CFD) technology was applied to carry out the numerical simulation.The results showed that the temperature distribution of the whole fire field was roughly the coneshape,and the flame temperature could reach up to 1 500 K.In the longitudinal view,the bottom temperature was higher,and the upper temperature decreased gradually.In the radial view,the center temperature was higher,and the surrounding temperature decreased gradually.The maximum thermal radiation intensity was 132 kW/m2,and with the increasing distance from the tank wall and the tank top,the thermal radiation intensity decreased gradually.The phenomenon of flame entrainment existed at the upper area of tank,and the flow velocity at the center was the largest,up to 56 m/s,and the phenomenon of flame sticking to the wall existed at the bottom of tank.The volume fraction distribution of combustion products (CO and CO2) were obtained,and the flame height was deduced to be 120 m with the volume concentration of CO being 0.001 as the judgment basis.The research results provide theoretical support for the prevention and control of such fire accidents in the future.
