요약
본 연구는 자체제작 축소모형 실험 장치를 이용하여 목재를 대상으로 침윤소화약제의 소화성능평가를 수행하였다. 축소모형실험의 최적조건 확인을 위해 소화용수의 양과 목재의 수를 변화시켜 조건설정 실험을 진행한 결과 20 pieces의 목재를 적층한 후 물과 소화용수 100 mL를 살수한 경우에 한하여 소화성능의 변별력을 확인하였다. 따라서 해당 조건에서 현재 사용되고 있는 국내외 침윤소화약제를 대상으로 소화성능을 평가한 결과, 물의 경우에서만 재 발화가 발생하는 것을 확인하였다. 또한 살수 시간에 따른 온도분포를 통해 소화능력의 변별력을 판단할 수 있었다. 본 실험 결과를 바탕으로 추후 최적화 침윤소화약제 성능평가 방법을 제시하는데 기초자료로 활용할 수 있을 것으로 판단된다.
Abstract
In this study, the extinguishing performance evaluation of wetting agent for wood crib was conducted by using a scale model equipment that we designed. To confirm the optimal conditions of the experiment, a test was changed amount of fire extinguishing water and the number of timber. As a result, the discrimination of the fire extinguishing performance was seen only when 20 pieces of wood and the extinguishing water of 100 mL were used. After evaluating the extinguishing performance of domestic and foreign wetting extinguishing agents under these conditions, a reignition was occurred in only when we used water. In addition, the discrimination of extinguishing performance was seen through the temperature distribution according to the time of watering. Based on the results of this experiment, this study is expected to be able to use as a basis on presenting a method of optimized performance evaluation of wetting extinguishing agent.
