Erosive Properties of Pulverized Coal Fly Ash (Review)

Fly ash produced from burning pulverized coal mainly consists of solid amorphous aluminosilicate spheres, which, with the exception of small particles, determine its erosive properties. Erosive wear and properties of the particles depend to a large extent on external conditions, and specifically, on fuel preparation and combustion. As far as the experimental …
