Abstract: Addressing wildfires has become increasingly important. To enable robust fire prediction and protection strategies, a deeper understanding of biomass ignition, pyrolysis behavior, and gas phase reaction kinetics is essential. In this exploratory study, a stagnation-plate burner setup was used to investigate the ignition and early combustion behavior of cylindrical pine wood samples under controlled conditions. Time-resolved thermocouple measurements were recorded at multiple heights above the surface and withinthe solid phase; they allow for the characterization of temperature distribution and provide data for model validation. Microscale combustion calorimetry (MCC) was employed to quantify the heat release characteristics of the wood. Preliminary simulations using OpenFOAM for the solid phase and Fire Dynamics Simulator (FDS) for the gas phase were performed. Initial results show the capability of both tools to replicate the key trends of the experimental setup. The results confirm that the setup enables controlled combustion and heat transfer conditions, which are rarely achievable in open fire scenarios. It allows for reproducible data acquisition and provides a valuable benchmark for validating pyrolysis and combustion models.
