GONZALEZ HASSIG, Andrés; GARCIA UBAQUE, César Augusto  e  TALERO ROJAS, Gabriel Fernando. Pilot plant study for waste wood pelletization and their use as fuel in brick ovens. Tecnura [online]. 2014, vol.18, n.40, pp.62-70. ISSN 0123-921X.

Abstract Biomass is one of the most suitable materials as an alternative fuel, but characteristics like moisture, oxygen excess content and low calorific value, this material requires pre-treatment processes. Pelletizing enables biomass for use directly on thermal processes. Brick sector has high energy demand for drying and firing processes and the use of fuels from biomass allows significant reductions in atmospheric emissions. This study compared energy and environmental performance of fuels from two types of pelletized biomass (waste from pruning of grass, shrubs and trees of the city) and sawdust waste. The biomass with best performance was sawdust, because of their lower energy consumption in pre-treatment process. Further, there was found a reduction in the cost of fuel between 7% and 10% supply, replacing 20% of the coal used in the process with biomass pellets.
