Abstract
The TG-DTA-DTG thermal analysis technology was applied to study the combustion model and combustibility of two kinds of biomass.Combustion characteristics of two kinds of biomass were analyzed according to combustion characteristics parameters such as ignition temperature, peak temperature at maximum weight loss rate, burnout temperature, maximum rate of combustion etc.Kinetic parameters and combustibility parameters were calculated.It shows that combustion model of two kinds of biomass is different, and the ignition temperature is about 280 ℃, and the burnout temperature is about 500 ℃, and combustibility parameters of biomass is better than coal, and first order reaction model is appropriate to describe the combustion of biomass.
