Characterization and microgasification of biomass pellets from woody waste for cooking and heating

Abstract

The main objective is to characterize the biomass obtained from the woody residues of Eucalyptus globulus in the rural community of San Francisco de Raymina, Ayacucho region, at 3800 meters above sea level, for its transformation into pellets and energy use through the microgasification process, in order to satisfy the cooking and heating demands of rural homes. Pellets are a solid biofuel that allows the energy content of residual biomass to be used more efficiently. The characterization of the Peruvian biomass was carried out in the laboratory of the Renewable Energy Research Institute (IER) of Castilla–La Mancha University, Albacete, Spain, and in the Renewable Energy Laboratory of La Molina National Agrarian University, Lima, Peru, with the purpose of comparing results using the ISO 17225-2 standard. The results indicated that the residual woody biomass of the eucalyptus tree from the Peruvian locality has a high energy potential (19.75 MJ/kg) and low levels of sulfur, chlorine and ash, which allows its use in the form of pellets. biomass. The optimal composition of the pellets was experimentally determined using local inputs to achieve an ecological biomass fuel for rural domestic use using micro-gasification stoves.
