This work is focused on the study of the coal devolatilization and on its influence on the whole combustion process. The pyrolysis is particularly important since ignition is controlled by the combustion of volatiles that evolve and successively burn. The analysis of the devolatilization process has been performed with a dedicated scientific software FG-DVC (Functional Group-Depolimerization Vaporization Cross-Linking model) and supported by experimental tests with TGA (Thermogravimetry Analysis). Kinetic models of the pyrolysis have been developed and implemented into a CFD code (FLUENTTM) to analyze the burner behaviour.
