Abstract:
Color,fineness,particle size distribution,chemical composition,mineral composition,particle morphology,chemical activity and hydration characteristics etc.of CFB(circulating fcuidized bed)ash for coal gangue power plant are analyzed,and resource utilizations of CFB ash in physical waste heat,landfill,building materials,agricultural and chemical products are reviewed.In this paper,it is necessary to carry out a comprehensive research on the basic characteristics of different CFB ashes and find out the commonness and difference between different CFB ashes that can be comprehensively used,and make CFB ashes are used for high-added-value products by appropriately modifying.In addition,the research of bulk utilization technology on CFB ashes used in building materials also should be fully carried out.
