초록

본 연구에서는 소형(1L 미만) 재충전 가능 프로판 용기의 안전성을 향상시키기 위하여, 화염 노출 시나리오에 대한 실험을 실시하였다. 화염에 노출된 용기는 내부 프로판의 액팽창에 의해 내압이 급격히 상승하게 되어 파열의 가능성이 존재한다. 따라서 내부의 과압을 해소시키기 위한 열 감응식 안전밸브를 부착하여, 용기가 파열되지 않고 내부 프로판을 외부로 분출하도록 유도하였다. 용기를 감싼 화염의 온도는 평균 $600^{\circ}C$였으며, 안전밸브를 통해 분출되는 프로판이 2차 연소를 유발하여 최대 $700^{\circ}C$까지 상승하였다. 그 결과 용기의 변형은 발생하였지만, 파열은 일어나지 않았다. 프로판용 압력용기의 화염시험 규정이 존재하지 않는 만큼, 화염에 노출 가능성이 존재하는 레저용 용기에 대한 선행연구로써, 본 연구의 결과는 추후 프로판 압력용기의 성능 평가에 있어 중요한 자료가 될 것으로 기대한다.

To evaluate the safety of propane cylinder, the flame test was performed by the flame exposure scenario of propane cylinder. The cylinder which was exposed in a flame was rapidly occurred to increase the internal pressure by liquid expansion, if so it cause of physical explosion. Therefore, the cylinder which was applied with thermal pressure relief device sholud be not bursted and the propane should be discharged to outside safely. The flame average temperature that was around of cylinder is $600^{\circ}C$, and then it increased $700^{\circ}C$ by discharged propane. The result of flame test, the cylinder was deformed, but it was not bursted. The regulations of flame exposure test for propane cylinder were not restricted, this paper can be applied to restrict the flame test if the cylinder is possible to expose the flame. Also, the results is expected as reference for estimation of the pressure cylinder performance.
