Fuelwood characteristics of ten fast-growth species in Costa Rica
The aim of this study was to investigate the fuelwood characteristics (calorific value and fuelwood value index) of ten species utilized in commercial reforestation in Costa Rica. It was evaluated too the chemical characteristics (cellulose, lignin, ash, carbon and nitrogen) and physical properties...

It was evaluated too the chemical characteristics (cellulose, lignin, ash, carbon and nitrogen) and physical properties (moisture content, green density and specific gravity) on these species. The results showed that the maximum calorific value ranged from 16500 to 20594 kJ/kg for sapwood and from 16258 to 20119 kJ/kg for heartwood. It was not possible to establish if heartwood has best fuelwood characteristics in relation to sapwood. The fuelwood value index presented large variations, from 337 to 6390. The effect of moisture content on the calorific value was linear and can be modeled by Y= β0*X+ β1. This relationship varied for each species or type of wood (heartwood or sapwood). Just Cupressus lusitanica between 10 studied species, presented the greatest fuel potential due to its high fuelwood value index, calorific value and low ash content. Others reforestation species, although not exhibit same fuelwood values than C. lusitanica, they have a significant energy potential due to the high volumes of waste obtained from different industries. El objetivo de este estudio fue investigar las características de combustibilidad (poder calórico e índice de combustibilidad) de diez especies de plantaciones de rápido crecimiento en Costa Rica. También fue evaluada la influencia de los componentes químicos (celulosa, lignina, cenizas, cantidad de carbono y nitrógeno) y algunas propiedades físicas (contenido de humedad, densidad verde y peso específico) sobre estas características de combustibilidad. Los resultados mostraron que el poder calórico máximo varió de 16500 a 20594 kJ/kg para la albura y de 16258 a 20119 kJ/kg para el duramen. No fue posible determinar cuál tipo de madera (albura o duramen) que presenta el mayor valor de poder calórico. En el caso del índice de combustibilidad, se presentaron grandes variaciones, con valores entre 337 y 6390. Al evaluar los efectos de la humedad se encontró un efecto lineal sobre el poder calórico (modelo Y = β0*X + β1) y muestra que el efecto de la humedad en el poder calórico es diferente para cada especie o tipo de madera (duramen o albura). La única conífera evaluada (Cupressus lusitanica) fue la especie con mayor potencial energético debido a sus altos valores de índice de combustibilidad, poder calórico y su bajo contenido de cenizas. Las otras especies de plantación, a pesar de que no presentan los valores energéticos de C. lusitanica, poseen un potencial importante debido a los altos volúmenes de desechos o residuos que se obtienen en las distintas industrias. 2013-04-26 2017-09-19T20:37:03Z 2017-09-19T20:37:03Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/kuru/article/view/1321 10.18845/rfmk.v10i24.1321 https://hdl.handle.net/2238/8319 spa https://revistas.tec.ac.cr/index.php/kuru/article/view/1321/1224 application/pdf Editorial Tecnológica de Costa Rica Revista Forestal Mesoamericana Kurú; Vol. 10, Núm. 24 (2013); Pág. 26 - 33 2215-2504 |
