摘　　要：本文运用PyroSim火灾动态模拟软件,对某加油站站房火灾的发生、发展过程进行了数值模拟,简要讨论了火灾过程中温度、CO、烟气蔓延、能见度、火焰发展和热释放速率等关键参数的变化规律。从模拟过程及结果来看,PyroSim火灾动态模拟软件能较好地模拟火灾发生和发展过程,其强大的数据后处理功能,能得到直观形象的数值结果,计算结果与实际站房火灾烟气蔓延趋势吻合较好。本文的研究方法与结论可为加油站火灾安全的性能化设计提供一定参考。Fire simulation software PyroSim was used to simulate the occurrence and development pro-cess of a station building fire in a gas station. The variation of key parameters, such as tempera-ture, CO, smoke spread, visibility, flame development and heat release rate etc., in fire process were discussed briefly. From the simulation process and results, the fire software PyroSim can better simulate the process of fire occurrence and development, and its powerful post-processing function of data can also get visualized numerical results, and the calculated results are in good agreement with the fire smoke spread trend of the actual situation. The method and conclusions of this article can provide some useful references to the design of a gas station.
