Abstract

This study used Auto Ignition Temperature Tester (KRS-RG-9000) and Dual Cone Calorimeter(ISO 5660-1) in 14 representative species of trees as part of research on the fire watch of crown fire in the formed tree of sub-tropical forest and considered the initial combustion characteristics such as ignition characteristics and heat generation characteristics and fire load. In the green leaf, the percentage of moisture content was 116-248%, which differed according to the species of trees and the Daphniphyllum macropodum which showed the highest percentage of water content, which was 2.14 times more than the Abies koreana Wilson which showed the lowest percentage of moisture content. Flameless igniting temperature was 251-383° and Quercus serrata and Carpinus tschonoskii showed a relatively lower flameless igniting temperature, and the flameless igniting temperature of Carpinus tschonoskii was 6 TC, which showed the shorted time than the other species of trees. Both total heat release and mean heat release rate showed the highest values in six species of trees such as yew, Taxus cuspidata, Prunus maximotviczii, Betuta ermani var. communis, Carpinus tschonoskii, Acerpalmatum, and Acer pseudo-sieboldianum. Based on these findings, a colony of yew, Taxus cuspidata, Prunus maximowiczii, Betuta ermani var. communis, Carpinus tschonoskii, Acer palmatum, and Acer pseudo-sieboldianum has a high fire load according to the high heat generation rate when its crown fire proceeds and the fire strength is expected to be big, and as Carpinus tschonoskii has a high risk of ignition, it is considered that its fire spread will proceed rapidly on forest fire.
