Although 60 to 70% of fly ash has been utilized in highly developed countries, no country has completely solved this problem. The fly ash collected in power plant electric precipitators has the following advantages: These soots are dry (do not need to be dried like other raw materials); are powders (particle size from 1 to 200 microns), have There are many characteristics of white pelican ash (slag); this kind of ash comes from power plants, and power plants compare
