Vantagens e desvantagens na substituição da queima de cavaco de eucalipto por um queimador de resíduo agrícola como fonte de energia na secagem direta de grão na região dos Campos Gerais - PR

Abstract

This study analyzes the replacement of eucalyptus chip burners with agricultural residue burners as an energy source in the direct drying process of grains in the Campos Gerais region, Paraná, Brazil. The main objective was to map and assess the advantages and disadvantages of this change, considering energy, operational, economic, and environmental aspects. A comparative methodology was used, conducting drying tests with both types of fuel over a 60-hour period, monitoring drying efficiency, ash production, calorific value, material consumption, and environmental impact. The specific objectives included evaluating the energy efficiency of the replacement, comparing the calorific power of the biomass types, analyzing operational impacts, and identifying economic and environmental benefits of the new solution. The results indicated that although agricultural residue has a lower energy density and requires more technical adjustments, it offers advantages in terms of sustainability and cost reduction, proving to be a viable alternative to eucalyptus chips.
