“…The volatiles of the bamboo which will control the burnout rate, were less than <75% targeted limit for biomass fuels. Finally, the heating value, which provides the measure of energy content of the fuel, was 17.7 GJ/tonne, which should allow for high boiler efficiencies with boilers and allow for co-combustion with coal systems (Demirbas, 2007;Porteiro et al 2010;Engler et. al, 2012).…”

Bamboo is one of the world's fastest growing plants making it a promising energy crop. Due to its size and harvest seasons, bamboo has similar logistics as woody resources. Additionally, recent advances in micropropagation may allow significantly lower plantation establishment costs, allowing for the expansion of feedstock production. To investigate the potential of this feedstock for solid fuel, Phyllostachys bissetii bamboo culms were obtained and processed into solid fuel pellets at a pilot scale. The experiments indicated that high quality pellets were able to be produced under similar operating conditions as wood pellets. Additionally proximate, ultimate, and elemental ash tests were performed on the pellets which indicated that P. bissetii should perform similarly to wood solid fuels in boiler operations. From these results we concluded that P. bissetii bamboo has significant potential as a biomass feedstock source for thermal conversion.

“…Cuando la combustión de la biomasa se lleva a cabo en hornos de lecho fijo, las tres etapas ocurren como frentes que se propagan en contracorriente con el aire primario (Porteiro et al, 2010). El calor transferido desde la llama, tanto por convección como por radiación, a las capas de biomasa fresca permite el secado y la devolatilización del material.…”

Abstract:The furnaces used for the manufacture of sugar cane have energy losses due to incomplete combustion of sugar cane bagasse and sensible heat in the flue gases. During production of sugar cane, bagasse from sugar cane is used as fuel, with mass fractions of humidity between 30% and 50%, which affect the combustion efficiency in the furnace. The objective of this research is to study the influence of bagasse which is introduced into the furnace of a fixed bed, features, analysis and conclusions. Looking establish operating conditions that lead to obtain the best performance in the combustion of biomass.Keywords: Sugarcane bagasse, combustion, fixed bed oven, brown sugar.Resumen: Los hornos utilizados para la elaboración de la panela presentan pérdidas energéticas debido a una combustión incompleta del bagazo de caña de azúcar y al calor sensible en los gases de chimenea. Durante el proceso de producción de la panela, el bagazo de caña de azúcar se utiliza como combustible, con fracciones másicas de humedad entre 30% y 50%, las cuales afectan el rendimiento de la combustión en el horno de lecho fijo. El objetivo de esta investigación es estudiar la influencia del bagazo de caña que se introduce en el horno de lecho fijo, sus características, análisis y conclusiones. Buscando establecer las condiciones de operación que conlleven a obtener el mayor rendimiento en la combustión de la biomasa.Palabras clave: Bagazo de caña azúcar, combustión, horno de lecho fijo, panela.

This paper presents a methodology to simulate the combustion of fixed beds of biomass particles using computational fluid dynamics (CFD) techniques. The models presented were used in the simulation of a domestic pellet boiler working under operating conditions and the model predictions were compared with measurements of heat transfer, temperature and species concentration. The same procedure was then used to simulate the same domestic boiler working with different values of water temperature and the influence of water temperature variations on the main variables was analyzed.Keywords: simulation; CFD; combustion; biomass; boiler Mass fraction of species generated in the bed [-] Void fraction [-] CO to CO 2 ratio [-] Air excess ratio [-] Dynamic viscosity [kg mStoichiometric coefficient of the pellet consumption [-] Mass fraction in volatile gas [-] Sphericity [-] ′′′
