结合某工程实例,采用FLUENT软件对流化床车间生产单元氢气泄漏燃烧、硅烷泄漏燃烧时的火焰温度和热辐射进行模拟分析,确定影响火灾的相关因素,并使用TNT当量法分析可燃气体泄漏后车间的爆炸危险性。结果表明,泄漏孔径对火灾范围影响重大;环境风速能降低硅烷火焰温度;爆炸破坏半径随时间和泄漏孔径的增加呈现非线性增长。
Combining with an engineering example, the FLUENT software was used to simulate the hydrogen leakage, the flame temperature and the heat radiation during the silane leaking combustion. The relevant factors affecting the fire were determined and the TNT equivalent method was used to analyze the flammable gas leakage Workshop explosion danger. The results show that the leakage aperture has a significant impact on the fire range. The ambient wind speed can reduce the temperature of the silane flame. The explosion radius increases nonlinearly with the increase of time and leakage aperture.
