요약

산소소모법을 이용한 화재발열량 측정장치를 구성하고 대표적인 주택가연물(침대, 책상, 냉장고, 장롱)에 대하여 화재 발열량을 측정하였다. 발열량 측정 결과 최대 발열량은 각각 냉장고 1MW, 책상 0.8MW, 장롱 4.2MW, 침대 0.4MW로 나타났으며, 특히 냉장고와 장롱의 경우 화재성장속도가 상대적으로 빨라 위험요인이 큰 것으로 나타났다.

Abstract

Heat release rates of main combustibles in residence area were measured by a calorimeter using oxygen consumption method. It was found that the peak heat release rates of the combustibles were 1.0MW for a refrigerator, 0.8MW for a desk, 4.2MW for a wardrobe and 0.4MW for a bed. Especially, the refrigerator and wardrobe were found to be very hazardous because of their fast fire growth rate.
