Smoke exhaust temperature in electrical instrument-controlled room fire of a nuclear power plant
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.
