The combustion characteristics of bio oil from flash pyrolysis of biomass were investigated by thermogravimetric method and the effect of heating rate on combustion temperature was also studied. The kinetics of the combustion reaction was studied and the kinetic parameters were also calculated by Sharp method. The results show that the combustion reaction can be well described by three first order reactions. Therefore, the bio oil can be burnt up easily as fuel in boiler.
