The increase of international coal market has created new power operational problems and the need to reduce the carbon levels in ash below around 6% in order to render the pulverized fuel ash saleable as well as maintain the combustion efficiency. Compared with the Northern hemisphere coals, many Gondwana coals contain high levels of maceral of the inertinite group. The inertinite maceral group is commonly regarded as the main source of unfused, chars and this can increase problems with carbon carry-over in the fly ask leading to less overall efficience, and cost are incurred in its disposal. Since coal is a very heterogeneous material consisting of different organic substances (macerals) and mineral matter to know the behavior of the different macerals in the combustion is important. The propose of the present work was to investigate the influence of maceral association in the burning profile of coal.
