En el presente estudio, se utilizó carbonilla de carbón vegetal y aserrín de Pinus radiata (D. Don) para fabricar pellets, con similares características en peso, volumen y densidad, manteniendo como única variable, la cantidad de aserrín y carbonilla en cada pellets. Utilizando una prensa de tornillo manual, se elaboró un total de 1180 pellets con 15 proporciones distintas de carbonilla y aserrín. Con estos pellets se realizaron ensayos de friabilidad y poder calorífico. Esta última propiedad se determinó utilizando un protocolo de medición y la Norma alemana DIN 51900. Según los resultados, se concluye que es posible fabricar pellets de carbonilla, utilizando aserrín de Pinus radiata (D. Don) como material aglomerante, con un 50 % de ambas materias primas, obteniendo la combinación óptima con un 47,5% de carbonilla y una friabilidad de 0,935, logrando una ganancia energética de 24,25% con respecto a un pellet de 100 % de aserrín.<br>In the present study, it was used charcoal of vegetal coal and sawdust of Pinus radiata (D. Don) to manufacture pellets, these had similars characteristics by weight, volume and density, keeping as the only variable, the sawdust and charcoal quantity of each pellet. Using a manual screw press, was manufactured a total of 1180 pellets with 15 different charcoal and sawdust proportions. With these pellets were conducted a friability and calorific power essays. This latter property was determined using a protocol for measuring and German Standard DIN 51900. According to the results, was concluded that is possible manufacture pellets of charcoal, using sawdust of Pinus radiata (D. Don) as a adhesive material, with 50% of both raw materials, obtaining the optimum combination with a 47.5% of Charcoal and a friability of 0.935, achieving a gain energy of 24.25% compared to a 100% pellets of sawdust.
