Abstract

On account of limited attention paid to the influence of orientation and altitude in previous research, the pyrolysis and ignition characteristics of wood in different orientations and altitudes were investigated experimentally. Two orientations were explored: vertical and horizontal. In addition, experiments were conducted in Lhasa and in Hefei, which are at very different altitudes. Ignition time, mass loss rate, and surface temperature are discussed. Compared with those in the horizontal orientation, shorter ignition times, faster mass loss rates, and lower surface temperatures were observed in the vertical orientation. In addition, there are shorter ignition times, faster mass loss rates, and higher surface temperatures in Lhasa (high altitude) than in Hefei (low altitude).
