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

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.
