Abstract

The biomass pellet fuel has the advantages of easily to be stored and transported,convenie -ntly to be used,clean and environmental friendly as well as high combustion efficiency. On the fou -ndation of studying combustion process, this paper obtained the industry analysis values of eight kinds of biomass pellet fuels by experiment. Combined with fire indicator of Fu-Zhang and combus -tion characteristics indicator of Yan Niu, the values of FZ and ZM are calculated, and then it is obtained that the decorative paper has the minimum ignition temperature, contrary the rice husk has the highest ignition temperature. Finally, by observing the morphology of ash after the burning of fuel combustion, it is pointed out that with increasing temperature from 740°C to 920°C, gray color of pell -et fuel gradually from black to white, hardness gra -dually hardened by the soft, even coke residue.
