This site has the best information about pipe insulation I have come across. That spun fiberglass wrap? It has the lowest R value and the greatest amount of labor with it.

Hot air forced through the bottom of the pulverizing chamber removes unwanted moisture and transports the pulverized coal dust up through the top of the pulverizer and out the exhaust pipes directly to the burner. The more recent coal pulverizer designs are Vertical Roller Mills. Figure 2 shows a cutaway view of a Babcock and Wilcox MPS Pulverizer.

Nov 17, 2012· 15.Erosion in Pulverizer Erosion by mineral particles picked up in the air stream carrying pulverized coal through the mill, classifier, exhauster, and transport pipe is a recognized problem. Erosion can produce holes in steel liners and deep depressions in large section cast parts. There has been success in the industry using ceramic materials.
