  • Proximate and elemental analysis, determinations of density, caloric value and TTI were made on six kinds of biomass pellets made from bamboo powder, wood powder, Chinese fir shaving, tree bark, cotton stalk and cornstalk. The results showed that the total moisture, density, ash content, volatiles and fixed carbon of tested biomass pellets met the requirements of SS187120. Elemental analysis demonstrated that the content of N and S of tested pellets was 0.51%-3.45% and 0.03%-0.22%, both were lower than that of the coal, indicating clean energy. Cone calorimeter method with fire indicators of Fz showed that the ignition temperature of tested pellets was ordered by wood powder>Chinese fir shaving>bamboo powder>tree bark>cornstalk>cotton stalk. Integrated indicators resulted that properties of pellets from wood powder was the best, with calorific value of 20.64MJ/kg, total moisture of 6.49%, ash content of 0.41%, volatiles of 82.01%, fixed carbon of 11.09%, the content of N of 0.51%, the content of S of 0.03%, time to ignition of 13 seconds.
