Abstract: The continuous search for more efficient alternatives in the use of energy resources at industrial processes has allowed the implementation of different proposals such as the co-processing of fuels for the generation and use of heat. In this study, a thermogravimetric evaluation was carried out on five coal samples belonging to the bituminous categories from the Colombian departments of La Guajira, Cundinamarca and Boyacá, which were characterized by proximal, elemental analysis, free swelling index and power, according to Standards. ASTM (ref). Sugarcane bagasse was also evaluated by proximate analysis, sulfur content and lignocellulosic composition. These materials were subjected to a thermogravimetric analysis (TGA) in an air atmosphere to select the fuel with the best characteristics for the combustion process. Additionally, additional parameters were determined such as the combustion temperature (Tm), the maximum speed at which the highest conversion is obtained, as well as the regions in which the main related events occur under non-isothermal conditions. The results show that the coals with the best behavior in the combustion process are those that contain a high content of volatile matter, a low content of ash and that do not have agglomerating properties. In this sense, sample A-10, from La Guajira, is the more appropriate coal with better characteristics, since it presents physicochemical conditions with values of 40.16% m, slmm of MV; 5.14 %m, bs of CZ and a free swelling index of ½, constituting a classification of non-binding material, it is also concluded that the TGA analysis is a quick and versatile tool to evaluate the behavior of fuels, during the coal/biomass co-processing, for final selection.
