A one-dimensional integral model is formulated to describe the transient burning behavior of charring material. The transient burning of material is divided into the following sequential phases : (I) temperature rise and ignition of the virgin material receiving external heating, (II) pyrolysis of the virgin material layer and char layer oxidation, (III) residual char oxidation after the consumption of all the virgin material. The results are shown to be in reasonable agreement with experimental data in the existing literature for mass loss rate. The burning model is then incorporated into a single zone method-based compartment fire model. The fuel inside the compartment is divided into multiple fuel elements, and the compartment fire behaviors are simulated as consequences of the burning of each of these elements. The comparison with experimental data in the literature also showed reasonable agreement.
