Mineralogy and Physical and Chemical Characteristics of Coal Ash from Yang Zonghai Power Plant

摘要

The modality,physical and chemical characteristics. mineralogy and distribution of particle size of coal ash were studied by modem analytic technology SEM,spectral analysis,X - ray Diffiaction (XRD) and laser granularity analyzer. The test results show that the mineralogy of coal ashes is dominated mainly by mullite,quartz and hematite.The coal ash of Yang Zonghai power plant has lower content of calcium oxide and is low calcium ash.At the same time,the losing amount is low to bum.The particle diameter is small and mainly concentrates on the range of 1-40 μm.
