In this study, mathematical models of coal carbonisation in the coke oven have been developed. Models for thermo-physical properties(e.g. specific heat, density, and thermal conductivity) and heat of carbonisation reaction of coal during thermal decomposition to coke have been constructed in terms of the changes in the chemical composition and structure. To have sufficient generality for the applications to coke oven practices, the model describes the kinetics of release of main volatile matter constituents, thereby permitting the changes in the mass and composition of solid residue to be estimated by element balances. Correlations for the parameters of the models are derived so that prediction of volatile matter evolution can be made from coal ultimate analysis and heating profile. The computer based model predictions are in reasonable agreement with the experimental data generated by conducting pertinent experiments and literature information.
