Two fire source scenarios, which are shielded and unshielded pool fires, respectively, are used. In the shielded pool fire tests, the results show that the pool fire can be extinguished by the conventional sprinkler and high-pressure water mist suppression systems. However, the extinguishing time for conventional sprinkler protection system is longer. For 6-nozzle and 4-nozzle tests in the water mist system, they take 44s and 73s as well as 23.21 L and 25.01 L of water quantity to extinguish the shielded pool fires, respectively. For the comparison between shielded and unshielded pool fire tests, the extinguishing times for the use of 4-nozzle are 73s and 89s, whereas they are 44s and 40s for 6-nozzle. Apparently, the obstruction seems to have no obviously influence on the fire suppression effectiveness. Chiun-Hsun Chen 陳俊勳 2004 學位論文 ; thesis 52 en_US |
