Effect of primary air preheating and moisture sugarcane bagasse during fixed bed combustion

Furnaces used to making jaggery have energy losses due to incomplete combustion of sugarcane bagasse and sensible heat in the flue gases. During jaggery production process, sugarcane bagasse is used as fuel, with mass fractions of humidity between 30% and 50%, which affect the combustion efficiency...

During jaggery production process, sugarcane bagasse is used as fuel, with mass fractions of humidity between 30% and 50%, which affect the combustion efficiency of a biomass in a fixed bed. Because the air preheating decreases the drying time, its implementation in many biomass combustion systems increases process efficiency. Therefore, in this investigation we studied the influence of the moisture content and the preheating of the primary air on the combustion of bagasse in a fixed bed furnace, by analyzing the profiles of temperature and concentration of the combustion gas. Results showed that increasing in bagasse moisture m reduces the rate of combustion and conversion of carbon to CO2, diminishing the yield of process. When the primary air is preheated to a temperature of 120 ºC, the combustion rate increased, however, only meant an increase in combustion efficiency to a mass fraction of 30% humidity. Los hornos utilizados para la elaboración de 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 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 de una biomasa en lecho fijo. Gracias a que el precalentamiento del aire disminuye el tiempo de secado, su implementación en muchos sistemas de combustión de biomasa ha incrementado la eficiencia del proceso. Por tanto, en la presente investigación se estudió la influencia del contenido de humedad y el pre­calentamiento del aire primario sobre la temperatura, la composición del gas y la tasa de combustión, mediante un diseño experimental factorial mixto 3x2. Los resul­tados demostraron que el aumento en la humedad del bagazo de caña reduce la tasa de combustión y la con­versión de carbono a CO2, y por tanto, el rendimiento del proceso. Cuando se precalentó el aire primario hasta una temperatura de 120 ºC, la tasa de combustión au­mentó, sin embargo sólo significó un incremento en el rendimiento de la combustión para una fracción másica de humedad de 30%.  2019-08-09T19:29:59Z 2019-08-09T19:29:59Z 2013 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://revistacta.agrosavia.co/index.php/revista/article/view/263 10.21930/rcta.vol14_num1_art:263 http://hdl.handle.net/20.500.12324/35142 reponame:Biblioteca Digital Agropecuaria de Colombia repourl:https://repository.agrosavia.co instname:Corporación colombiana de investigación agropecuaria AGROSAVIA spa http://revistacta.agrosavia.co/index.php/revista/article/view/263/268 application/pdf Corporación Colombiana de Investigación Agropecuaria (Agrosavia) Ciencia y Tecnología Agropecuaria; Vol 14 No 1 (2013); 5-16 Ciencia y Tecnología Agropecuaria; Vol. 14 Núm. 1 (2013); 5-16 revista Corpoica Ciência e Tecnologia Agropecuária; v. 14 n. 1 (2013); 5-16 2500-5308 0122-8706 10.21930/rcta.vol14-num1
