某核电厂电气仪控房间火灾排烟温度分析
摘要：对某核电厂电气厂房的2个电气仪控房间进行了火灾排烟温度模拟分析。模拟计算了排烟系统不同时刻启动时，这2个防火空间室内空气温度的变化情况。结果表明：排烟系统启动后房间空气温度迅速降低，然后逐渐升高，最后随着火灾热释放速率的降低而逐渐降低；对于手动启动的排烟系统，需及时启动才能有效排除火灾中的烟气；需合理设置排烟防火阀，以保护排烟风机等。
关键词：核电厂防火空间火灾排烟温度热释放速率

Smoke exhaust temperature in electrical instrument-controlled room fire of a nuclear power plant
Abstract: The fire smoke exhaust temperature of two electrical instrument-controlled rooms in the electrical factory building of a nuclear power plant is simulated and analysed. The changes of indoor air temperature in two fireproof spaces are simulated when the smoke exhaust system starts at different times. The results show that the room air temperature decreases rapidly after the start of the smoke exhaust system, then increases gradually, and finally decreases with the decrease of the fire heat release rate. For the smoke exhaust system started manually, it is necessary to start in time to effectively remove the smoke in the fire. Smoke exhaust fire dampers need to be set up reasonably to protect the smoke exhaust fan and so on.
