Abstract
Using FDS simulation, under specific quantity of mechanical smoke exhaust, the ef ect of different spacing of water mist sprinkler on the fire smoke control was observed in case of a fire occurs in underground mal . From the analysis result, under the condition of fire power is 5 MW, smoke exhaust volume is 60 m3/(h m2), nozzle spacing is 2.0 m, the extinguishing effect is best, the design of fire protection in large space with sprinkler spacing of 3.0 m is more economic.关键词
