요약
본 연구에서는 형식이 각기 다른 3종류의 미분무수 노즐을 사용하여 방사높이와 화염의 위치 변화에 따른 소화성능 실험과 포 소화약제를 혼합한 소화성능 실험을 수행했다. 소화성능 실험에서는 미분무수 노즐의 높이를 4m, 3.5m, 3m로 변화를 주었으며 연료 팬을 노즐 중심으로부터 0m, 0.5m, 1m의 변화를 주었다. 포 소화약제는 3%형 AFFF(Aqueous Film Forming Foam)를 사용하였다. 실험결과 개구부의 유무는 소화에 미치는 영향이 적었으며, 포 소화약제를 혼합한 미분무수의 소화성능은 약제를 혼합하지 않은 경우에 비하여 우수하였다.
Abstract
We carried out fire extinguishing experiments with three kinds of water mist nozzle system. Fire extinguishing experiment according to installed nozzle height and fuel pan location was done. And fire extinguishing performance was compared with plain water and foam agent mixed solution. Water mist nozzle height was varied with 4m, 3.5m and 3m and position of fuel fan was varied 0.5m and 1m from the center of water mist nozzle. Foam agent that used in this experiment is 3% type of AFFF (Aqueous Film Forming Foam) solution. Experimental result showed the door opening effect was little. Fire extinguishing performance of foam agent mixture water mist was better than the plain water mist only.
Key Words: Water mist, Fire extinguishing, Foam agent
