dc.descriptionEste artículo presenta los resultados del análisis técnico (basado en la cantidad de exergía) y ambiental de una planta termoeléctrica de 50 MWe nominales, localizada al sur del estado de Santa Catarina (Brasil), diseñada para operar con carbón pulverizado y adaptada para operar en proceso co-firing carbón-biomasa residual. Además de la planta termoeléctrica, el estudio consideró una frontera extendida que involucró los procesos relacionados con la obtención, transporte y manipulación tanto del carbón como de la biomasa. El análisis exergético siguió lineamentos de la segunda ley de la termodinámica, mientras que el análisis ambiental se realizó siguiendo la metodología de análisis de ciclo de vida (ACV), considerando 1 MWh como unidad funcional y la categoría de impacto en el calentamiento global, mediante el método IPCC 2007 GWP 100 años. Para ambos casos (operación solo con carbón y en co-firing), el análisis exergético indicó que la planta termoeléctrica responde por más del 95 % del total de la exergía consumida. Para el análisis ambiental, los resultados indicaron que para la operación solo con carbón se emiten 1230 kg de CO2-eq por MWh, mientras que para la operación en co-firing, con una participación de hasta 10 % de biomasa en base energética, el valor efectivo de la emisión fue de 1103 kg de CO2-eq por MWh.spa
dc.description.abstractThis paper presents a technical (base on exergy) and environmental analysis concerning an existing 50 MWe steam power plant located in the south of Santa Catarina state - Brazil, designed to operate with pulverized coal and modified to operate in co-firing process coal -biomass. In addition to the power plant, the study considered an extended boundary that involves the processes related to the obtaining, transport and handling both coal and biomass. The exergy analysis was focused in the second law of thermodynamics, while the environmental analysis followed the Life Cycle Assessment (LCA) methodology took into account as functional unit 1 MWh and the global warming impact category, following the IPCC GWP index over 100 years. For both cases (only coal and co-firing), the exergetic analysis indicated that the power plant is responsible for over 95% of the exergy consumption. Results indicated that for the case of operating only with coal, are emitted 1230 kg of CO2-eq per MWh, whereas for operation in co-firing, with a share of 10% of biomass on energy basis, the value of the issue it is 1103 kg CO2-eq per MWheng
