The formation of fouling in the walls of the combustion chambers has been a limiting factor for the use of solid biomass as fuel for direct burning in non-rudimentary furnaces. Despite its high lignin content, with high Calorific Power, the biomass composed of residues of floating species of the Eichhornia crassipes species has been subject to restrictions of use. To contribute with the technology of adaptation of solid biomass use in furnaces of superior technology, this paper presents the potential of plaster waste to be as a promising material to reduce fouling generated by direct combustion of vegetable biomass. Macrophyte pruning residues were used in this study for pellet´s preparation that were filled by gypsum residues. An addition of gypsum residues to vegetable biomass pellets keeps lower heating value and can reduce maintenance time of furnaces due to decrease in standard fouling content in tens of percent.
