Abstract

An analytical method based on the theory and experimental techniques of differential scanning calorimeter is proposed to investigate the determination of the heat of reaction for wood in experiments with and without crucible lids. It is found that the heat exchange dynamics are different for the two cases during decomposition which causes the rate of energy transfer to differ and the values of heat of reaction to vary quantitatively. However, these results still demonstrate consistent energy absorbing and releasing behaviour during the decomposition process in both lid scenarios. In addition, the quantitative differences for the heat of reaction only have a weak effect on the predictions of burning behaviour for cone calorimeter simulations in Fire Dynamics Simulator.
