The nonisothermal unreacted‐core‐shrinking model with unsteady state heat transfer analysis has been experimentally evaluated. The system studied is the combustion of a single agglomerated carbon‐fire clay sphere in a thermobalance. By comparing the experimental results with those predicted by the model, it is concluded that the model adequately describes the reaction system under the experimental conditions such that the ash layer diffusion is rate controlling.
