Resumo
Given the present concern about the decrease of fossil fuels supply, and taking into account their contribution to the greenhouse effect, several studies propose different solutions to the problem. Among these solutions, there is the use of biomass. It is considered to be a clean and renewable energy, which can be used for heating and obtaining electricity, and has been drawing attention because of its availability and variety, as it is obtained from waste and exploration sources. The characterization of this energy source is essential for the selection of the type that will bring the most benefits and efficiency. A method that can be used is the "Combustion Index" (ICOM), which relates during combustion process, the burning time, increase in temperatures and decrease of fuel mass (biomass consumed). This work is a study of biomass combustion characteristics through ICOM and mass residues quantification after combustor burning, for three typical biomasses at the Cerrado, a biome from Brazil´s Central-West region: forest biomass (Eucalyptus), residual biomass from extractive harvesting activities (Bocaíuva) and waste to energy biomass from industrial activities (Crambe).
