利用物理模型对立式水管锅炉爆炸前运行压力的估算

Estimation of the operation pressure of vertical water tube boiler before explosion based on physical explosion model

在一起立式水管锅炉爆炸事故分析中,由于现场损坏严重,安全附件和记录均已经严重破损,不能够有效提供锅炉爆炸前运行参数。基于安全评价理论中的物理爆炸模型,通过现场飞出碎片的测量,对该锅炉爆炸前的能量和运行压力进行了估算。该估算结果与其他方法进行评估的结果相一致,为事故分析提供了重要参考依据。

In a certain vertical water tube boiler explosion analysis, all the safety accessories and records have been damaged and no data related with before explosion could be found. Based on the physical explosion model in safety evaluation, the boiler energy and operation pressure before explosion was estimated by the measurement of flying debris. The estimated results which were consisted with the results of other methods provided important reference basis for the accident analysis.
