          Abstract:The affecting factors of the preparation process and the physical and mechanical properties of the circulating fluidized bed combustion (CFBC) fly ash ceramsite were studied. The results showed that the calcium sulfate contained in the CFBC fly ash had the effects of aerogenesis foaming and fluxing agent in the sintering process,which made the ceramsite easy to form vitrified surface and cellular structure with porous interior. The effect of the mass ratio between the alkali oxide and the silicon aluminum oxide on the performance of the CFBC ash ceramsite was mainly reflected in the effect of the fluxing element on the generation of liquid phase in the surface and interior of the ceramsite during the sintering process. After the process optimization,the 700-grade CFBC ash ceramsite as lightweight aggregate was prepared. The production automation process of CFBC fly ash ceramsite and the feed forward-cascade control system for removal of SO2 from production of ceramsite were designed.
