Abstract:

Flame radiation hazard of petrochemical plants' flare systems was studied from fluid dynamic. CFD technique was used to simulate flame radiation under 500 t/h discharge and radiation field around flare was established. The software Statistica was used to fit the relationship between heat radiation intensity and horizontal distance to the center of flame. Based on safe heat radiation intensity 81.5 m is obtained as the safety distance for personnel on the ground according to the requirement of the standard SH3009-2001. This safety distance is important for emergency response and personal protection.

Key words: Elevated flare , Heat radiation , CFD simulation , Safe distance

摘要： 从流体力学角度研究大型石化企业高架火炬事故状态时火焰热辐射的危害性，应用CFD数值模拟技术对其排放量为500 t/ h时的火焰热辐射进行了数值模拟，建立了火焰周围的热辐射强度，Statistica软件拟合数据得出热辐射强度与距离火焰中心的水平距离的对应关系式。根据《石油化工企业燃料气系统和可燃性气体排放系统设计规范》SH3009 - 2001中规定的人体所能接受的安全热辐射强度计算得出地面操作人员安全间距的参考值为81 .5 m，对事故状态时的应急救援和人员防护起到一定的指导意义。
