ENERGY ASSESSMENT OF WOOD CHIPS OF THE INDUSTRY OF PUEBLA STATE

92% of the energy produced worldwide for the heat generation is obtained by the use of biomass, the remaining percentage is acquired from the electricity generation and the fossil fuels. Mexican temperate forests and tropical forests have the capacity to cover more than five times the primary resources that require. The wood chip produced from forest residuals is an important fuel, previously it was used as an intermediate product in the manufacture of boards and pellets. Its use for energy purposes to power the cauldrons of big industries has increased, since energy is produced at lower economic and ecological costs. In Mexico, there are no entities that give reference to regulate wood chips as a bioenergetics, for that reason the aim was the characterization of the wood chips for use as a biofuels of the following forestry species: Quercus sp, Hevea brasiliensis, Mangifera indica and Pinus sp. from the Puebla forest industry. The moisture content (CH), higher calorific value (PCS) and ash content (CC) was determined. The average CH was 10%. Respect to the PCS, there was significant differences between the forestry species studied. The average values were: 19.2 MJ/kg for Pinus sp, 17.8 MJ/kg for Quercus sp, 17.7 MJ/kg for H. brasiliensis and 16.8 MJ/kg. for M. indica. Quercus showed the highest mean value of CC (5.2%), with respect to the H. brasiliensis (5%), M. indica (4.9%) and Pinus (4.8%). For their PCS´s value, the species were classified statiscally into three groups: A) Pinus sp, B) Quercus sp and H. brasiliensis and C) M. indica. In regard to the values of CC, two groups were formed: A) H. brasiliensis, M. indica and Pinus sp and B) Quercus sp. Based on the PCS´s value, the species of groups A and B were the best to be used as a biofuel.
