The Ignition Characteristics of Tree Branches, Barks, Living Leaves and Dead Leaves in Pinus Densiflora and Quercus Dentata
소나무와 떡갈나무의 주요 부위별 착화특성에 관한 연구
Abstract
In this study, we have carried out test to examine the ignition characteristics, such as a relation of moisture content and combustibility, and ignition temperature using KRS-RG-9000 tester, of significant part of above trees which are representative species of Young Dong Province of Korea. After rainfall, the percentage of moisture content of living leaves and branches was between 52 and 70%. But it was just between 17 and 33% after 144 hours drying at normal temperature. For dead leaves, it was 10% lower than of first. There was a significant difference on ignition characteristics. The hazard of ignition is highest on dead leaves. The ignition temperature of barks and branches is higher so a retard time is long than of living and dead leaves at normal temperature.
본 연구에서는 영동지역의 임상별 대표 수종인 소나무와 떡갈나무를 대상으로 주요 부위별 함수율 측정 및 건조속도와 가연성과의 관계, KRS-RG-9000의 발화온도 시험기를 사용하여 착화특성을 고찰하였다. 강우 후의 함수율은 대체로 생엽과 가지부위가
