“…World pellet production had an accelerated growth in recent years, of 7 to 19 million tons from 2006to 2012(FAO, 2012, mainly due to the increased demand generated by environmental policies and bioenergy use goals in Europe (DUCA et al, 2014). Pellet production in Brazil is evolving slowly, largely because of the little information on the product and the industry, with a small-scale production in 14 factories of 60,000 ton/year (ABIPELL, 2013) intended mainly to the thermal market (ESCOBAR, et al, 2014).…”

“…Se analizan y discuten los resultados obtenidos de las pruebas aplicadas a los pellets de acuerdo a los métodos antes mencionados: • Dimensiones: Comparando los resultados obtenidos con los criterios evaluados en la norma austriaca ÖNORM M7135, se nota que en cuanto a las dimensiones de los pellets no se cumple con esta norma, pues estas deberían estar entre 6 y 10 mm, pero al comparar estos parámetros con la norma europea CEN/TS 14961 especificaciones y propiedades para los pellets (CEN/TS EN 14961-2, 2012), la norma sueca SS 18 71 20 especificación de tres clases de pellets en función del tamaño y de la cantidad de cenizas que generan y la norma italiana CTI R04/05 que establece los parámetros de calidad de los pellets de biomasa con fines energéticos, se afirma que los pellets objetos de esta investigación cumplen con el parámetro de dimensiones el cual debe ser menor o igual a 25 mm (Duca et al, 2014); los demás parámetros de estas normas son muy similares, por esta razón se tomó como referencia la norma ÖNORM M7135 para producir y evaluar el comportamiento de los pellets.…”

ResumenLos biocombustibles, demandan procesos de caracterización y transformación confiables que aseguren su adecuado proceso de fabricación para que los usuarios finales los utilicen sin riesgo alguno. Alrededor del 4,42% de los biocombustibles que se comercializan a nivel mundial se presentan como aglomerados o pellets. Teniendo en cuenta que Colombia es un país con altas reservas de carbón y que como país agrícola produce grandes cantidades de residuos orgánicos, se encontró que la mezcla de estos dos productos presenta beneficios desde el punto de vista energético y de combustión, facilitando su quema y disminuyendo emisiones tanto de material particulado como de gases con contenido de azufre. Se presentan los resultados de la caracterización según normas internacionales de pellets producidos en el Laboratorio de Energías Renovables de la Universidad Nacional de Colombia de mezclas 50/50 de carbón antracita y madera. La evaluación fisicoquímica se hizo aplicando parámetros de la norma Austriaca ONORM M7135, con el fin de evaluar cada uno de los ítems allí establecidos. Además, se dan a conocer los resultados de las pruebas y los análisis de la caracterización de estas mezclas, así como su poder calorífico según norma ASTM D5865 11a y su resistencia al impacto según norma ASTM D440-86. Adicionalmente se discuten las ventajas y desventajas desde el punto de vista ambiental que acarrea el uso de los biocombustibles aglomerados.Palabras Clave: pellets; biomasa; poder calorífico; Caracterización de biomasa.

Caracterización Físico -Química de Pellets producidos a partir de mezclas 50/50Carbón Bituminoso/Madera Residual 19 AbstractBiofuels demand characterization and reliable processes to ensure proper manufacturing process for end users in order to use them safely. About 4.42% of biofuels that are marketed globally are presented as agglomerates or pellets. Considering that Colombia is a country with high coal reserves and, as an agricultural country, produces large amounts of organic waste, our results show that the mixture of these two products has benefits in terms of energy and combustion, facilitating burning and decreasing the emissions of both particulate material and sulfur-containing gases. This article presents the results of the characterization as international pellets produced in the Laboratory for Renewable Energy of the National University of Colombia for 50/50% mixture of wood and anthracite. The physicochemical parameters evaluation was made using the standard Austrian ONORM M7135, in order to evaluate each of the items established. Also test results and analysis of the characterization of these mixtures and their calorific value according to ASTM D5865 11a and the impact resistance according to ASTM D440-86 are shown. Additionally the advantages and disadvantages are discussed from an environmental point of view related to the use of biofuels agglomerates.

“…Due to that fact, more and more countries promote the use of renewable energy sources. Pellets are one of the most used forms of biomass in domestic equipment, standing out due to their uniformity and their high bulk density, which allow their transportation and handling in automatic systems [1].…”

Abstract:In recent years, the biomass market has constantly increased. The pellet manufacture industry has started looking for new products, such as wastes from forest, agriculture, and agroindustrial residues, among others, with the potential to be used as biofuels. However, some of these wastes have some characteristics that make both the combustion process and operating and maintenance conditions of thermal equipment difficult. Thus, further research to optimize the performance and ensure the compliance of the maximum atmospheric levels is needed. In order to carry out these studies, the design and implementation of a supervision, control, and data acquisition system for a domestic pellet boiler was carried out, which makes obtaining further information about the performance of non-conventional biofuels possible. Thus, these biofuels, coming from different sources, underwent different working regimes, facilitating the understanding of the results and the correction of limiting elements. The results from initial tests were reliable and precise, coinciding with the check readings that were done with a thermometer and a combustion gas analyser. Under these conditions, the system designed constitutes a fundamental tool to examine thermal processes with alternative biofuels, with the objective of making the most of different biomass wastes as renewable energy sources.
