| Abstract | This work discusses the effect of char burning mechanism on overall wood heat release rate (HRR). Five different kinetic models for char combustion were used in numerical simulation of a cone calorimeter experiment. Results of heat release rate per unit area (HRRPUA) from the simulations were compared against the experimental results. The investigated models were variations of oxidation and gasification mechanisms. Oxidation mechanisms overestimated the char consumption and the overall HRR. The gasification mechanism under estimated the char consumption and the overall HRR from the wood sample. The best performance was obtained from a combined oxidation-gasification model. The model assumes parallel partial oxidation by oxygen and gasification by carbon dioxide forming carbon monoxide in the gas phase. |
