Abstract:
In this study, the combustion process of a Korean wood pellet was observed through experiments and numerical analysis from 500 °C which is low temperature. Based on the experimental results, the combustion process was classified into gasification, flame burning, and char burning. In every phase of the combustion process, flame shape, mass change, and conversion time were measured and compared with the data in the literature. At lower temperatures, the gasification process occupied a significant portion of the overall conversion time and flame burning time reduces. Numerical analysis shows that the temperature inside the pellet was uneven in the flame burning mode but it became uniform in the char burning mode. Conversion time was predicted accurately through numerical simulation at 800 °C, but numerical prediction deviated from the experimental data at a low temperature.
