Análise do potencial energético dos resíduos da casca do coco verde gerados no município de Paraipaba/ CE proposta de uma planta térmica

Abstract

Currently, there is strong pressure from society to replace fossil fuels with other energy sources with less polluting potential. In view of this, the use of renewable energy sources has achieved special growth. The application of plant biomass, in particular, can be strategic, both from the point of view of energy generation and from the environmental point of view, given that many residues have a high potential for use due to their calorific powers and the use of Plant biomass promotes the capture of carbon dioxide generated in combustion processes. In view of this, the present work carried out a technical survey about the use of green coconut shell biomass in the municipality of Paraipaba/CE. It was found that the treated residue has a high potential for use, especially in the region of the Curu-Paraipaba irrigated perimeter, with a Lower Calorific Power calculated at 11.63 MJ/kg. From this, a preliminary sizing of a thermal plant was carried out to generate steam from the selected residue, arriving at the need for a 1 MW plant to take advantage of the available residue raised. Finally, an evaluation process was carried out for the boiler used in the sizing, aiming to determine the overall efficiency of the steam generation process, which resulted in approximately 57%.
