Forest biomass has been gaining representativeness in the Brazilian energy sector each year, due to its renewable production potential and the numerous products generated for the purpose of replacing fuel oil. Thus, the objective of this study was to estimate the energy parameters of fuels commonly used for energy production and to calculate the maximum price to be paid for each type of fuel analyzed. Initially, the characterization of fuels (pellets, wood chip, firewood with 0.45, 0.50, and 0.55 g.cm-3, and fuel oil) was carried out based on the available literature, collecting data basic density , moisture content and higher calorific value. The estimation of the parameters for the calculation of the maximum price was made by obtaining the net heating value of each fuel, being possible to obtain the energy density of each fuel. The simulation of the maximum price was made based on the energy equivalence between the fuels, obtaining the maximum price to be paid for each fuel in relation to the fuel oil. Was considered a change in the price of fuel oil between R $ 1200.00 and R $ 1300.00.m-3. It was observed that renewable fuels have a lower energy density than fuel oil due to the low density of the solid product in relation to the liquid and the low heating value resulting from the presence of hydroxyl groups in the molecular structure of renewable fuels. Pellets are the fuels that allow to pay a higher price among the renewables, due to its high density and lower moisture content, the price being between R $ 339.89 and R $ 368.22.m-3. It is concluded that renewable fuels have the potential of replacing fuel oil for energy purposes, due to economic and mainly environmental factors. Pellets are the renewable fuels with better energy characteristics compared to the others.
