[Abstract]:Combined with an engineering example, the flame temperature and thermal radiation of hydrogen leakage combustion and silane leakage combustion in fluidized bed workshop production unit were simulated and analyzed by using FLUENT software, and the relevant factors affecting the fire were determined. The TNT equivalent method is used to analyze the explosion hazard of the workshop after the flammable gas leakage. The results show that the leakage aperture has a great influence on the fire range, the ambient wind speed can reduce the flame temperature of silane, and the radius of explosion damage increases nonlinear with the increase of time and leak aperture.
