초록

이 연구는 재선충 감염 소나무와 비 감염 소나무의 수분함유율에 따른 연소열 실험을 통해 열적특성을 비교 분석하였다. 실험 결과는 다음과 같다. 수분 함유율 분석 결과는 재선충 감염 소나무의 경우 평균 19.92%, 비 감염 소나무는 26.27%로 화재 시 전도, 대류, 복사열 크기가 커질수록 수분 함유량이 감소한다. 수분 함유량의 기화가 가속되면 평형 수분 함유율에 도달하고 수분 함유율이 15%이하에서는 열원에 의하여 착화되지 않는다는 목재의 열적 특성에 상반되는 결과이다. 연소열 분석 결과는 재선충 감염 소나무와 비 감염 소나무는 연소열은 약 3%로 큰 차이를 보이지 않았다. 하지만 연소열이 다른 수종에 비해서는 높은 수치를 나타낸다는 것을 알 수 있다. 결론적으로 전도, 대류, 복사열의 증가에 따른 수분 함유율의 감소가 착화에 직접적인 원인 중 하나이며 수분 함유량이 감소할 수록 화재 확산 속도도 빨라진다는 것을 알 수 있었다.

This study compared and analyzed the thermal characteristics based on the ratio of moisture content of infected and non-infected Bursaphelenchus Xylophilus by heat of combustion experiment. The experiment results are as follows. The analysisresult of the ratio of water content shows that 19.92% on average for infected Bursaphelenchus Xylophilus and 26.27% for non-infected which decreases water content as the size of conduction, convection, and radiant heat increases in case of fire. As the vaporization of the moisture content accelerates, the average moisture content is reached, and the result is contrary to the thermal characteristics of the wood that the moisture content is not ignited by a heat source when the moisture content is under 15%. The combustion heat analysis result showed that infected and non-infected Bursaphelenchus Xylophilus had no significant difference in combustion heat at about 3%. However, it shows that combustion heat is higher than other species. In conclusion, decreasing in moisture content based on the increasing conduction, convection, and radiant heat is one of the direct causes of ignition, and the lower the moisture content, the faster the fire spreads.
