摘要：

Thermogravimetric(TG) analysis is used to investigate combustion characteristics and kinetics of corn straw pellets and their biochars. Combustion behaviors of biochars produced at 320, 500℃ are analyzed through different heating rates (10, 20, 40℃/min). As the results, burning DTG curves of corn straw pellets and their biochars show different peaks shapes, and the peak shifts to high temperature zone. The ignition and burnout temperature of corn straw pellets are less than biochars, and the integrated combustion characteristic index(SN) is greater than biochar pellets. With the increasing of carbonization temperature, the ignition temperature and burnout temperature increases, SN decreases. It is also found that the first order reaction kinetics model is suitable for expressing the combustion kinetics of corn straw pellets and their biochars. All correlation coefficients of the fitting curves are greater than 0.9. © 2019, Editorial Board of Acta Energiae Solaris Sinica. All right reserved.
