Characteristics and properties of torrefied biomass pellets from Gmelina arborea and Dipterix panamensis at different times
(Revista Chapingo, Serie Ciencias Forestales y del Ambiente, 2016)
Torrefaction and pelletizing were studied in the generation of energy from
lignocellulosic residues to increase the energy properties of the biomass. The aim of
this study was torrefied sawdust from Gmelina arborea and ...
Reducing warp and checking in 4 by 4 beams from small-diameter tropical species (tectona grandis, gmelina arborea, and cordia alliodora) obtained by turning the pith inside out.
(Forest Products Society, 2015)
Small-diameter logs from plantation trees are prone to warp and to produce checks due to the presence of juvenile wood, growth stresses, and asymmetric shrinkage during the drying process. In the present study, we analyzed ...
Parámetros Energéticos de Residuos de 10 Especies Forestales de Rápido Crecimiento
(Instituto Tecnológico de Costa Rica., 2013)
Aunque, los residuos de plantaciones forestales de rápido crecimiento en los trópicos recientemente han tomado importancia para su aprovechamiento en energía, aún no se cuenta con la información suficiente sobre sus ...
Evaluation of biodeterioration and the dynamic modulus of elasticity of wood in ten fast-growing tropical species in costa rica exposed to field testing
(Statny Drevarsky Vyskumny Ustav, 2015)
In tropical regions, it is possible to produce a large variety of timber species in plantation conditions. However, wood from these trees has low natural durability. Biodeterioration and the dynamic modulus of elasticity ...
Production and quality analysis of pellets manufactured from five potential energy crops in the Northern Region of Costa Rica
(Biomass and Bioenergy, 2016)
Modifications to a pellet manufacturing process must be made based on the characteristics of raw
material used. The purpose of this work was to determine the alternations required to a wood pellet
manufacturing process ...
Mineral content in relation to radial position, altitude, chemical properties and density of persian ironwood
(Universidade Federal de Sao Carlos, 2015)
Persian ironwood (Parrotia persica) is native species from Iran and covers 10,54% of the commercial volume. Its wood structure and its chemical composition are affected by growth conditions. The aim of the study was to ...
“Efecto de los acabados en la durabilidad de la madera de 10 especies provenientes de plantación forestal de rápido crecimiento”
(Instituto Tecnológico de Costa Rica., 2013)
Las condiciones ambientales presentes en toda la franja tropical, por sus altas temperaturas y la
presencia de precipitaciones, a lo largo del año, propician que en países como Costa Rica se
puedan desarrollar una gran ...
