Analysis of the Gaseous Emissions and the Residues Generated under Oxy-fuel Combustion of Biomasses

Some environmental problems are caused by pollutants from thermoelectric plants, mainly by burning fossil fuels. Alternatives for reducing such emissions are discussed worldwide and using green fuels is a promising way. Five biomasses (pine sawdust, sugarcane bagasse, coffee and rice husks and tucumã seeds) were evaluated for application as feedstock in thermochemical processes. Particular attention is devoted to the residues and emissions (CO, CO2, SO2 and NO) produced by biomasses burning in a Drop Tube Furnace (DTF). Oxy-combustion (CO2/O2:60/40%) experiments were performed and emissions monitored continuously. Thermal analysis, scanning electron microscopy, and energy dispersive spectroscopy were used to characterize in natura biomasses and residues after oxy-fuel combustion.
