Description A working set of models to represent coal combustion. Lagrangian particle transport and radiative heat transfer in an LES framework has been implemented and tested. The simulation results of the flow field were compared to experimental data for both a reactive and non-reactive case, and an overall good agreement emerged. A simple method for
replicating pyrometer measurements was developed for the LES and results obtained from the method were compared to the experimental data. Finally the species concentrations were compared to experimental results for CO2, O2 and N2. The results show the potentials of using LES for pulverized coal combustion and open the way for further developments on the coal combustion models and the applications to more complex burners.
Exploitation Route LES for pulverized coal combustion could be used for further developments on coal combustion models and applications to more complex burners.
