Abstract: In this paper,the combustion characteristics of peach wood britteue fuel were tested and analyzed by thermogravimetric analysis and different heating rates in atmospheric atmosphere. The results showed that the ignition point temperature of the fuel increased from 246℃ to 260℃ with the heating rate increasing from 10℃/min to 30℃/min. The combustion stability and efficiency of the britteue fuel were the best,when the heating rate is 30℃/min,the combustion stability discrimination index R_Wis 0. 68 mg/ (min/K²),and the comprehensive combustion characteristic index S_Nis 5. 49×10^-9 mg² min²/K³.
