Catch-fire Temperature and Amount of Combustion-Heat on the Fuel of Miscanthus type

참억새(Miscanthus)燃料의 着火溫度 및 燃燒熱量

This study examined the relationship among catch-fire, burning, maximum temperature (MT), amount of combustion-heat (ACH), and combustive time (CT) in heating temperature treated with the same amount of each organ of Miscanthus. In the survey sites, about 19％ of the areaswere covered by Miscanthus types, and the dry weight of Miscanthus and debris on the ground were 1,164 and 178 g/㎡, respectively. At 350℃ and 400℃, the rise of temperature by Culm type (culms and ears) and Leaf type (leaves and debris) were 90℃ and 82℃, respectively. At 350℃, durning time (BT) of culms-200, ears-200, ears-200, leaves-200 and debris-200 was 0-10’30”, 0-07’40”, 0-04’20”and 0-02’40”, and that at 400℃ was 0-01’20”, 0-00’50” 0-00’35”and 0-00’30”, respectively. BT was shorter at higher temperatures, and BT of Leaf type was shorter than that of Culm type. The amount of samples consumed was as follows: Culm type (culms-200 and ears-200) was 14.6g and 12.6g more than Leaf type (leaves-200 and debris-200) at 350℃ and 400℃, respectively. The total amount of combustion-heat (TACH) of samples was 5,859.7 kcal. The amount of mean combustion-heat generated from sample at 350℃ and 400℃ differed little: 727.6 kcal (24.9％) at 350℃ and 737.3 kcal (26.0％) at 400℃.
