A Study of The Heating and Energy Efficiency of Thermally-Modified Firewood

Abstract

This study was performed to evaluate the suitability and burning characteristics of thermally modified wood for use as auto camping charcoal. Four aspects of the burning were measured using a cone calorimeter: ignition time, total heat released, heat release rate, and flame out time. In addition, elemental analysis was carried out using an elemental analyzer. Thermally modified wood has short ignition and flame out times because of its low Oxygen/Carbon rate. The total heat released and the heat release rate of thermally modified wood is higher than that of other wood due to its low oxygen and nitrogen rate and high HHV (Higher Heating Values). With a shorter flame out time, carbonization takes less time, and the maintenance time is longer. These characteristics of thermally modified wood make it favorable for use as auto camping charcoal.
