摘要
介绍了用于评价天然气管道失效危害的喷射火灾危害范围评价模型、GRI—00/0189危害范围评价模型及API pub 581危害范围评价模型的定量评价计算方法。以某天然气管道发生穿孔泄漏为实例,进行了模拟定量评价并做了对比分析。分析结果表明,喷射火灾模型与GRI—00/0189模型的危害半径相近,后者略大;GRI—00/0189模型得出的死亡区面积略大于另外2种模型得出的面积,其评价结果较为保守,分析得出的安全距离为200·5m。
The failure of natural-gas pipeline can lead to various outcomes that can pose a significant threat to people and property in the immediate vicinity of the failure location. Among the consequences, the most possible one is jet fire. Three types of quantitative evaluation models to the hazard area, that is, jet fire model, GRI-00/0189 model and API pub 581 model, are analyzed in the paper. Taking natural gas pipeline as an example, the quantitative evaluation for the hazard area caused by jet fire is carried out. And the hazard area after jet fire is calculated. Finally the result is analyzed through comparison.
