초록

국내 복합영상관의 단일 가연물을 대상으로 실물 화재실험이 수행되었으며, 측정된 열발생률(HRR)에 대한 디자인 화재곡선 방법(General 및 2-stage methods)에 따른 최대 HRR 및 화재성장률에 대한 정량적 차이가 검토되었다. 가연물의 용도 및 화재하중의 관점에서 대기공간과 영화상영관으로 구분되어, 총 12개의 가연물이 선정되었다. 주요 결과로서, 2-stage method 통해 산출된 최대 HRR 및 화재성장률은 General method의 결과와 정량적으로 큰 차이가 있음을 확인하였다. 초기 화재단계의 보다 정확한 화재성장률을 고려할 수 있는 2-stage method의 활용은 정확한 ASET과 RSET 뿐만 아니라 화재감지기 및 소화설비의 작동시간을 보다 정확히 예측하는데 매우 유용할 것으로 기대된다.

An actual fire test was performed on single combustibles placed in a local cinema complex, and quantitative differences in the maximum heat release rate (HRR) and fire growth rate were investigated based on the design fire curve methods (i.e., the general and 2-stage methods). In terms of combustible use and fire load, a total of 12 combustibles were selected, classified into cinema lounge and movie theater. It was found that the maximum HRR and fire growth rate determined using the two-stage method were quantitatively different from those of the general method. The application of the two-stage method, which can be used to determine the fire growth rate of the initial fire stage more precisely, could be useful in accurately predicting the activation time of fire detectors and fire-extinguishing facilities, as well as the available safe egress time (ASET) and required safe egress time (RSET).
