Abstract
The Charcoal of biomass stalk-coal mixtures at different mass fractions were obtained by thermogravimetry analyzer, and its combustion characteristics was studied. The results show that biomass can improve the combustion characteristics of charcoal formed by coal, but the combustion rate of the charcoal formed by the biomass-coal mixture is not in nonlinear relationship with the biomass mass fraction. It is suggested that it is caused by the difference of the combustion rate and oxygen consumption rate between biomass charcoal and coal charcoal.
