Development for the water mist package having a low pressure nozzles on wooden cultural properties and temples

The present study purposed to develop the water mist package system for the cultural properties fire prevention and fire suppression system through analyzing fire protection system and cultural property’s characteristic, and to suggest directions for the development of cultural property fire prevention system in the future. Maximum safety with minimum damage has issued a main objective in fire protection of the cultural property in Korea. Two types of the water mist nozzles having a low pressure had been developed by KEI. The one is for inside using in wooden cultural properties, the flow rate is 30∼35 ℓ/min and the discharging pressure is 13∼14 bar. The oother one is for out-side of wooden properties, the flow rate is 25∼30 ℓ/min and the discharging pressure is 14∼ 15 bar, the water drop size is 180∼200㎛(SMD). To evaluate the nozzles performance test, we made the fire scenario and full-scale model of wooden cultural properties for fire test. The size of full-scale model was 4.9m length, 4m wide, 6.6m height, all was made by wooden. This real fire test results shown that the low pressure water mist nozzles having a 200 ㎛ dorp size were very effectively fire extingushing and suprrseion on wooden cultural properties fire. Even though the oil fuel fire was not extinguished, the fire suppression effects for the during mobilization of fire brigade was enough.
