The effect of the heating and air flow rate on the mass loss of pine wood particles
Abstract
This paper presents the thermogravimetric analysis (TGA) and the kinetic study of the combustion of pine wood particles. The TGA experiments were performed, for three different particle sizes, by modifying the heating and air flow rate in order to study the influence of these parameters on the mass loss and the combustion behaviour. The results of this study presented that the heating and air flow rates have an influence on the thermal decomposition of pine wood particles but, the effect of the heating rate is more noticeable when compared to the effect of the air flow rate on the thermal decomposition of pine wood particles. The effect of the heating rate on the thermal decomposition behaviour was compared between low and high heating rates and, a displacement of the thermogravimetric and the derivative thermogravimetric curves to high temperatures. In this way, the heating rate also affects the highest mass loss rate temperature and the value of the mass loss rate. On the other hand, the effect of four different air flow rates was compared and similar results were obtained although, for all experiments, with 100 mL/min of air flow rate more energy was released and the burnout takes place a little earlier and with increasing the particle sizes at different air flow rate more energy is released. Relatively to the kinetic analysis it was verified, at various air flow and heating rates with different particle sizes, the highest activation energy was mostly obtained during char combustion. This study revealed that the combustion of pine wood particles with heating rate 5 °C/min has the highest reactivity for the global combustion except for middle particles. Meanwhile in the second and third stages higher heating rate has the highest reactivity. The highest reactivity occurs at lowest flow rate for all particles.
