Purpose: The study want to verify application the medium expantion foam extinguisher of expantion foam rate and fire extinguishing Performance test because the medium expansion system can maintain the discharge distance less affected by air currents, and the foam agent can be used efficiently. Method: For the study, the medium-expansion testing apparatus was manufactured and with synthetic surfactant foam agent of (class B) fire extinguishing model, and Fire Performance was analyzed for foam expansion rate and the fire agent consumption was measured and analyzed. Results: We measured the medium-spray testing apparatus and found that the expansion rate was 26.1 times. The test results of a 20-unit fire extinguishing model show that the extinguishing time is faster than the high and low foam expansion. It has been analyzed that it is possible to apply a hand-operated with a hose reel or medium expansion apparatus. Conclusion: Considering that the foaming agent and the extinguishing performance of the medium foam ratio are excellent, It is necessary to introduce the technical standards of medium foam agent for the introduction of hand-operated equipment, such as hose reel or portable medium foam apparatus.
연구목적 : 포소화설비에 사용되는 중발포 소화약제는 기류에 영향이 적어 방출거리를 유지 할 수 있을 뿐만 아니라 소화약제도 효율적으로 사용 할 수 있기 때문에 중발포기를 이용하여 발포배율 및 소화성능을 실험으로 밝히고자 한다. 연구방법 : 본 연구를 위해 중발포 시험장치를 제작하여, 합성계면활성제포를 대상으로 유류화재(B급) 소화성능 및 발포배율 분석과 포소화약제 소모량을 측정하고 분석하였다. 연구결과: 중발포기로 발포배율을 측정한 결과 팽창율이 26.1배의 중발포 배율로 나타났으며, 유류화재 20단위 소화모형 실험결과 소화시간이 고발포 및 저발포 보다 빠르게 나타나, 수동식설비인 호스릴 또는 중발포기 적용이 가능할 것으로 본다. 결론: 본 연구를 통해 중발포 포소화약제 발포성능 및 소화성능이 우수하게 나타나는 점을 고려하여 중발포 소화약제를 활용한 호스릴 또는 중발포기의 기술기준 도입이 필요하다.
