摘要
In this paper, a one-dimensional integral model is developed to describe the processes involved in the transient pyrolysis of a semi-infinite charring material subjected to a constant radiant heat flux. In this model, a special factor that shows the effect on pyrolysis is considered, i.e. under the oxygen-containing atmosphere. The model tracks the char layer depth, thermal penetration depth, surface temperature and mass loss rate. Comparison with experimental results demonstrates that the predictions of the mass loss rate and temperature profile within the charring material are in good agreement with the experiment.
