The fly ashes from coal A and B, generating from a shell coal gasifier in China, were sampled respectively to investigate the physicochemical characteristics of fly ash. The results show that Coal A is rich in Ca, and coal B is rich in Fe. The elements migration is different during gasification, and the influence of the coal type is significant. The number of fly ash particles in diameter at 1μm from coal A is much more than that of fly ash from coal B. There are many fine particles adhere to the big spherical fly ash particles. These small particles are rich in Al-Si and have the appreciable amounts of Ca with low fusion temperature, which may be the reasons for the fine particles sticking to the big spherical particles.
