요약
육상 및 해상에서 일어나는 화재를 진압하기 위한 가스계 소화설비 중 이산화탄소 소화설비는 우수한 성능 및 높은 경제성으로 인하여 널리 사용되고 있지만, 고농도 이산화탄소로 인한 질식사고가 빈번히 발생하여 안전문제가 항상 지적되어 왔다. 본 연구에서는 수치해석을 통하여 선박 내 압축기실의 이산화탄소 소화설비 화재 진압 특성을 예측하고, 이산화탄소 소화설비로 인한 질식사고를 방지하기 위한 2중 안전 제어기법을 제시하여, 이산화탄소 소화설비의 안전을 도모하였다. 수치해석 결과로는 4가지 시나리오를 선정하여, 화재발생 후 이산화탄소 소화설비 작동으로 인한 열발생률 변화, 온도변화, 이산화탄소 농도변화, 산소 농도변화 및 화재진압 특성을 고찰하였으며, 방호구역 내 환기팬 용량이 충분하지 않은 경우의 위험성 및 적절한 환기시스템의 필요성을 제시하였다.
Abstract
Carbon dioxide extinguishing systems are broadly used for onshore and offshore fire accidents because of excellent performance and low cost. However, there is risk with carbon dioxide systems, which have caused many injuries and deaths by suffocation associated with industrial and marine fire protection applications. In this study, a numerical analysis was performed to predict the fire suppression characteristics of a carbon dioxide system in the compressor room of ships. A double protection safety system is suggested to prevent suffocation accidents from carbon dioxide extinguishing systems. Four scenarios were selected to study the variation of the heat release rate, maximum temperature, a $CO_2$ and $O_2$ mole fraction, and fire suppression characteristics with the carbon dioxide system. The importance of proper design is suggested for a ventilation system in the compressor room of ships.
Key Words: $CO_2$ extinguishing system, FDS, Safety system, Suffocation accident, Compressor room, Sensor system
