Experimental Investigation on Pyrolysis Characteristic of Biomass Pellets

The biomass-fired boiler has been developed rapidly in China, and the biomass pellets are widely used. In order to analyze the fuel properties and pyrolysis characteristic of biomass pellets, the straw pellets and wood pellets are studied by thermogravimetric analyzer (TA) and large particle thermogravimetric platform. The results show that the pyroly- sis starting temperature of biomass pellets is low and the volatiles are high during the pyrolysis process, and the particle size also has an effect on the pyrolysis. Finally the pyrolysis kinetic parameters are calculated through the thermal kinetics meth- od.
