abstract="In order to provide the basic theory for numerical simulation and risk assessment of historic building fire, with naturally aging wood as research object, their appearance and thermal conduction characteristics and those of reference wood were analyzed by scanning electron microscopy ( SEM) and thermal property test from the perspective of natural aging. Then, their thermal release features at different stages during combustion were studied by using differential scanning calorimetry ( DSC), and effects of different heating rates on thermal behavior of aging wood were analyzed. Finally, their apparent activation energy distribution during thermal reaction was calculated and analyzed based on heat flow. The results show that the thermal diffusion ability of naturally aging wood is enhanced. Natural aging reduces the energy required in the ignition and combustion process of wood, and has a great influence on energy demand before ignition, thus greatly reducing peak energy barrier needed during ignition. © 2022, Editorial Department of China Safety Science Journal.
