Mathematical Modelling of Carbonisation Process in Stamp Charged Coke ovens

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.
