Experiment Study of Volatilization Combustion during Coalfield Fire
Experiment is a more direct and reliable way, through which the observation and data analysis can summarize specific qualitative and quantitative relationships and the fire mechanism and laws phenomenon. It can provide a reliable basis for the proposed theory or computational model from the general principle and validation for the theory or the results. Through experiment, heating process takes greatest impact on the heating surface but least on inner parts. While the temperature is ascent to some degree, the heating surface temperature will exceed the temperature and continue to be ascent, which indicates that the coal begins to oxide. While the airflow is increased, the temperature will be slightly increased. The temperature is descent more slightly in the coal temperature because of thermal radiation.
