Abstract：

Burning pulverized coal under high temperature will get pulverized fuel ash,which is a mixture and is similar to cinerite.Generalized pulverized fuel ash contains fly ash and slag.In China the pulverized coal ash emissions reached up to 0.125 billion tons in 1995,approximately 0.15 billion tons in 2000,0.375 billion tons in 2009.How to use this secondary energy source which is accumulated year in and year out,save more floor space,reduce environmental pollution,create higher added value profit,on which has been gradually placed a high value.Introduce the physical and chemical properties of pulverized coal ash and its comprehensive utilization in construction,building materials industry,agriculture,chemical industry.Analyze the development tendency of pulverized fuel ash,emphasize that refined and high benefit utilization technology is needed.

Key Words： coal-fired electricity generation;pulverized coal ash;cyclic utilization;environmental pollution
