EXPERIMENTAL STUDY ON FIRE PERFORMANCE OF WOOD AT EARLY STAGE OF FIRE

摘要

Early stage of fire is the beginning of fire. At this stage, fire behavior is mainly affected by properties of combustible materials. Three kinds of wood-beech, oak, and priceless-are chosen to study their fire characteristics at early stage of fire. Heat release rate, average heat release rate, valid combustion heat, and time to reach maximum heat release rate are measured using cone calorimeter. A simple model based on experiments is proposed to predict heat release rate. The time to reach maximum heat release rate is also predicted.
