| description | Sawmill residual product of Pylon (Hyeronima alchorneoides) and Eucalyptus (Eucalyptus spp) species was used to produce pellets under different conditions of densification. Experimental equipment was used to determine the thermal conductivity, thermal diffusivity and specific heat. Physicochemical properties of the pellets obtained under different conditions of densification, such as ash content and calorific value were determined. The content of nitrogen, chlorine and sulfur present in the material used to produce the pellets was estimated. Thermal conductivity values were determined between 0,253 W/mK and 0,279 W/mK; 1,748 m2/s and 2,314 m2/s for the thermal diffusivity, and in the case of specific heat values between 3,019 kJ/kgK and 2,183kJ/kgK were determined. The high heat values was between 18 907 kJ/kg and 18 960 kJ/kg, an ash content of 1,31 % on a dry basis was determined. Finally, it was determined that the content of nitrogen, chlorine and sulfur present in the residual biomass used, corresponds to 0,1129 %, 0,0592 % and 0,0317 %, respectively. A direct relationship between increasing the bulk density of the pellets and the thermal properties was determined. The calorific value and ash content were not significantly affected by the treatments applied. The estimated content of N, Cl and S corresponds to that expected in the selected biomass. Comparison of the properties of the pellets produced under the conditions studied -densification, against regulations-, showed acceptable results, entering these in terms of different categories of quality. |

Aserrín residual producto del aprovechamiento de la madera de las especies Pilón (Hyeronima alchorneoides) y Eucalipto (Eucalytus spp), fue empleado para elaborar pellets bajo diferentes condiciones de densificación. Se utilizó equipo experimental para determinar la conductividad térmica, difusividad térmica y el calor específico. Propiedades fisicoquímicas de los pellets obtenidos bajo las diferentes condiciones de densificación, tales como el contenido de cenizas y el poder calorífico fueron determinadas. El contenido de nitrógeno, cloro y azufre, presente en el material empleado para elaborar los pellets fue estimado. Se determinaron valores para la conductividad térmica entre los 0,253 W/m·K y 0,279 W/m·K; 1,748 m2/s y 2,314 m2/s para la difusividad térmica, y en el caso del calor específico se determinaron valores entre los 3,019 kJ/kg·K y 2,183 kJ/kg·K. El poder calorífico superior tuvo valores entre los 18 907 kJ/kg y 18 960 kJ/kg, se determinó un contenido de cenizas del 1,31 % en base seca. Finalmente, se determinó que el contenido de nitrógeno, cloro y azufre presente en la biomasa residual empleada, corresponde a un 0,1129 %, 0,0592 % y 0,0317 % respectivamente. Se determinó una relación directa entre el aumento de la densidad aparente de los pellets y las propiedades térmicas. El poder calorífico y el contenido de cenizas no se vieron afectados de forma significativa por los tratamientos aplicados. El contenido estimado de N, Cl y S corresponde al esperado en la biomasa seleccionada. Se corrobora que los pellets estudiados poseen características dentro de los parámetros recomendados por las normas estudiadas.
