Corresponding author： XU Kai-li, E-mail： kaili_xu@ aliyun, com） The physicochemical characteristics of corn cob ash obtained at different ashing temperatures （600 ℃ and 815 ℃ ） were studied with X-ray fluorescence spectrometry, X-ray diffraction, scanning electronic microscopy and experiment was adopted to study the influence of grading analysis. Muffle furnace burning ashing temperature and holding time on ash content. The ash composition and morphology of the fly ash samples collected from biomass gasification station were analyzed by using scanning electron microscopy （SEM） and energy disperse X-ray microanalysis （EDX）. The results indicated that ashing temperature has a remarkable effect on the ash granularity, content, composition, morphology and phase composition, bu |
