Fire Resistance of Four Coniferous Woody Species in Heilongjiang Province

Abstract:

On condition that the heat release rate is 50kW•m-2, the volume of a gas velocity is 24 L•s-1, the combustibility of Pinus koraiensis、Pinus sylvestris var. mongolica、Picea koraiensis、Larix gmelinii in Heilongjiang Province were determined systematically through the use of the controlled atmosphere tapered calorimeter. Through the comparative analysis of the heat release rate and the smoke production rate and some orther burning parameters of the barks and the withered leaves, combine the moisture content of barks and withered leaves of each species, evaluate the fire resistance of this four coniferous species. The results shown: the heat release rate, HRR; total heat release, THR; specific extinction area and smoke produce rate are higher in the barks and withered leaves of Picea koraiensis but the fire performance index is low, these instructions that the fireproof performance is worse in Pinus sylvestris var. mongolica; each Picea koraiensis burning indexs of the Larix gmelinii is lower or the lowest, both the smoke production rate, SPR and the heat release rate, HRR are slow, the fire performance index is high. However, its absolute moisture content and relative moisture content is the highest, it’s flammble.So,we conclude its fire-resistance performance is higher, we could choose it as the fire-preventing priority screening tree species; the flammability of Pinus koraiensis and Pinus sylvestris var. mongolica between the above two species. the combustion characteristics of trees is the result of multiple factor joint, The difference between the different research results is resulted in the choice of the indexs, so it’s urgent need to establish a comprehensive and integrated evaluation index system.
