Study on Characteristics in Combustion Process of Cornstalk and Wheat Straw

摘要

The TG-DTA-DTG thermal analysis technology was applied to study on combustion experiments of cornstalk and wheat straw.. Combustion characteristics of the two biomass was analyzed according to combustion characteristics parameters such as ignition temperature ,peak temperature at maximum weight loss rate, burnout temperature etc. By analyzed the combustion process of the two with the heating rate of 20 square/min, the bi-component phased reaction model is appropriate to describe the combustion process. A proper combustion mechanism was proposed. Comparisons of experimental results shows that there are some difference in kinetics parameters of the two kinds of biomass.
