Combustion of furniture wood waste and solid wood: Kinetic study and evolution of pollutants

摘要

This work is focused on the combustion processes of wood waste. Two kinds of waste have been studied: furniture wood waste (treated and used wood) and solid wood from factories (untreated wood). A kinetic study has been carried out for each material in air and an N-2:O-2 9:1 atmosphere with dynamic and dynamic + isothermal runs at different heating rates, considering the decomposition of the three main components of the wood and also the combustion of the char obtained. Satisfactory kinetic models were obtained for each kind of wood. Significant differences in thermal behavior were found between furniture wood waste and solid wood, probably due to the presence of additives and inorganic compounds in the furniture wood waste, which modifies the kinetic parameters of the thermal process.
