摘      要：An isothermal operation is implemented by employing a thermogravimetric analyzer (TGA) for simulating the thermal decomposition behavior of 58μm pine sawdust in air *** independent parallel reaction model is adopted in this study to describe the thermal decomposition *** Weibull distribution function is used to record and analyze the weight loss during isothermal decomposition at different temperatures(500,600,700,and 800°C).The total weight loss of the pine sawdust is assumed as a linear combination of individual weight loss from three components,including the char and two volatile *** plot of the thermal decomposition rate curve leads to kinetic parameters such as the reaction rate constants and the reaction *** results show that the Weibull distribution function successfully represents decomposition curves of three components,and fits the experimental data very ***,this study provides a simple way to evaluate the decomposition rate of biomass combustion in a real combustor.
