Study on the Thermal Degradation Kinetics of the Common Wooden Boards

The thermal degradation behaviors and kinetics of five common wooden boards were studied by TG-DTG techniques at different heating rates 10K/min, 15K/min, 20K/min, 25K/min and 30K/min in air atmosphere. The kinetic parameters, activation energy, of the degradation process for the wooden boards were calculated by means of Kissinger and Coats-Redfern methods. The results show that the whole course of pyrolysis of the five wooden boards can be divided into three phases and the main stage's activation energy of core-boards is the highest. It also shows that the results of Kissinger method are higher than Coats-Redfern's. The causes of the differences between the two methods and the probable factors causing errors during the experiment are also discussed.
