Study on kinetic characteristics in combustion process of biomass

This paper reports the experimental results on the thermogravimetric characteristic of straw combustion and influence of different experimental conditions upon the thermogravimetric characteristic of straw. The characteristic parameters of straw volatilization separating process are put forwardreaction dynamics equation of straw is established the index of the combustion characteristics and the are of differential apex are tested in the paper. It is suggested that the initial release temperature of corn straw and wheat straw volatilization reduces and the initial release temperature of rice straw volatilization decreases with the increase of the temperature-increasing rate. The activation energy of the three samples weakens with the increase of the temperature-increasing rate.The area of differential apex and the index of the combustion characteristics of straw increases with the increase of the temperature-increasing rate.
