Abstract

The properties of the wood pellets from damaged wood by forest fire and sound woods were investigated. Oven-dry densities of pellets made from sound wood and the damaged wood of Pinus densiflora were 0.93~0.94 and 0.86~0.88, respectively. Compressive strength of the pellets from the woods was ranged from 145 to $168kgf/cm^2$, and there was little difference between the sound wood and the damaged wood of P. densiflora. Ash content for the sound wood and the damaged wood of Pinus densiflora were 0.32~0.37% and 0.25~0.35%, respectively, and calorific values of each pellet were ranged from 18 to 19 MJ/kg. The result of elemental analysis in carbon. hydrogen and oxygen showed 45.8~48.8%, 6.2~6.5% and 46.5~48.0%, respectively. Consequently, there seem no significant difference in the properties between damaged and sound wood pellets.

목질 바이오매스 자원의 고도이용을 위한 연구의 일환으로 산불피해재와 정상재의 목질펠릿 특성을 조사하였다. 제조된 목질펠릿의 전건밀도는 소나무 정상재 및 피해재 각각 0.93~0.94, $0.86{\sim}0.88g/cm^3$로 나타났다. 각 시료의 압축강도는 $145{\sim}168kgf/cm^2$의 범위로서 소나무 정상재와 피해재 양자간에는 거의 차이가 없었다. 각 시료의 회분량은 소나무 정상재와 피해재가 각각 0.32~0.37%, 0.25~0.35%로 나타내었으며, 발열량은 18~19MJ/kg 범위로서 피해목과 톱밥 크기에 따른 차이는 보이지 않았다. 원소분석의 결과, 탄소 45.8~48.8% 범위이며, 수소와 산소의 경우 각각 6.2~6.5%와 46.5~48.0%로 나타났다. 결론적으로 산불피해재와 정상재간에 목질 펠릿의 특성의 차이는 거의 나타나지 않았다.
