The study is focalised to illustrate that innovative bioenergy systems are thermodynamically possible and that its would reach a very high efficiency. The suitably design and implementation of modern bioenergy system contributes to sustainable development, due to integrate technical feasibility with environment and socio-economic assessment. The proposed bioenergy systems are analysed for Pucalà sugar factory, Chiclayo (Peru), starting from current situation to the modern technology. The technological power plant is constituted by a indirect heating fluidised bed gasifier, a hot gas cleanup system and a Molten Carbonate Fuel Cell (MCFC). This system presents the higher electrical efficiency for the sugarcane trash. Furthermore, that is feasible the production of hydrogen rich gas from sugar cane residues (leaves, tops and bagasse) to be used in fuel cell systems. The investment and operational costs regarding the use of fuel cell, are higher than in other possible technological solutions if related to the amount of processed biomass, but are the lowest if referred, as usual, to the produced kWh. Moreover, since the technologies used are in the research and development phases, the costs are expected to dramatically decrease in the near future.

En este trabajo se ha hecho uso de un modelo de Dinámica de Fluidos computacional (CFD), como herramienta numérica para el diseño de una paila pirotubular que reemplazará a una plana aleteada que actualmente opera en el módulo “Cruz misionera”, esto con la finalidad de incrementar la eficiencia térmica y por lo tanto la producción de panela. Con este objetivo, la configuración original de la hornilla es simulada utilizando un modelo CFD para calcular el comportamiento térmico de ésta. Después los resultados numéricos son comparados con datos de mediciones en campo de manera de validar el modelo CFD. Posteriormente un nuevo diseño
de paila pirotubular es utilizado para reemplazar la paila plana aleteada, esto con la finalidad de estimar numerciamente la potencia térmica bajo las mismas condiciones de operación.
Despues de comparar ambas simulaciones se puede observar un incremento de un 105% en el proceso de Clarificación/evaporación cuando la paila pirotubular es utilizada. Esta mejora tiene un impacto directo en la producción de panela en donde la eficiencia térmica se incrementa de
31.4 a 42.8%.
