초록

본 연구에서는 국내 가열로 건조로의 안전장치 유무에 따른 위험변화를 평가하기 위하여 FTA(Fault Tree Analysis)를 통하여 안전장치들의 사고발생 빈도수 도출 및 분석을 실시하였다. 국내 LPG 가열로 및 건조로의 안전장치의 국내 설치기준이 미비하고 가스 누출하여 체류할 수 있는 구조로 폭발의 위험을 가지고 있다. 안전장치는 다른 설비의 연소기 국내 기준과 NFPA를 바탕으로 4가지를 선정하였다. 안전장치 설치 전후의 사고발생 빈도감소효과를 각각 분석하였다. 이를 통해 국내 LPG 가열로 건조로의 가스누출 피해 방지를 위한 최소한의 안전장치를 제시하였다.

The purpose of this study is to assess the risk of depending on the presence or absence of safety device of domestic heating and drying furnaces, by derivation and analysis of accident frequency of safety devices through FTA (Fault Tree Analysis). Installation standards are lacking in Korean for the safety device of LPG heating and drying furnace, which have a risk of explosion due to structure to trap the leaked gas. Four different safety devices were selected on the basis of NFPA and national standards for combustors of other equipment. Effects of frequency reduction in accidents were analyzed before and after installing the safety devices respectively. As a result, a minimal leakage safety device was presented for preventing damages from gas leak of domestic LPG heating and drying furnace.
