Abstract: In order to study the pyrolysis characteristics of waste bamboo flooring, the pyrolysis experiments of waste bamboo flooring particles were carried out by thermogravimetry. The pyrolysis parameters and thermogravimetry curves of waste bamboo flooring particles under different particle sizes, heating rates and atmospheres obtained by using the control variable method. The Coats were Redfern integral method was used for thermokinetic analysis, and the optimal mechanism function was selected. The results show that the pyrolysis of waste bamboo flooring can be divided into four stages, and the temperature range of each stage is about 20～100 ℃ , 100～200 ℃ , 200～384 ℃ and 384～800 ℃ respectively. Through the study of pyrolysis conditions, the particle size can affect the main weight loss stage of pyrolysis, which will delay the occurrence of this stage. The effect of heating rate on pyrolysis is mainly reflected in the third stage. The larger the heating rate is, the more intense the reaction is. Air can promote the pyrolysis, which can make the reaction more sufficient and the weight loss greater.
