- Abstract
Biomass ranks third as the greatest energy source for the conversion of electricity in Brazil, with sugarcane as the most relevant energy input. Bagasse is the residual biomass in the crushing process and its storage is required due to the production´s seasonality. Experiments have been undertaken for samples of stocked material in different positions (differentiated degradation) obtained in an agro-industrial unit with seventy thousand tons acquired for use in a steam boiler. Physical and chemical (immediate analysis, including humidity) and energetic (heat power) characteristics of sugarcane bagasse were evaluated when undergoing stocking conditions in the open air during three years. Climate influence and storage conditions were analyzed in alterations of the energy potential of residual biomass. The following results are underscored: a) specific mass was four times higher and TUM,BU reached 85% when bagasse was stored in the open air; b) decrease of TCZ (< 1%), making possible reduced damage and maintenance when used in steam boilers; c) without significant degradation as solid fuel with regard to TMV,BS and TCF,BS, provides respectively ignition and stability of fuel, and significant contribution in PCS; d) mean rates for calorific power will be consumed at 15% or more, within the process of bagasse drying; e) available thermal energy (-27 mil TEP) has a significant potential for the co-generation of energy and increase in aggregated value of agro-industrial production.
