Corrosion of Ash-Handling Systems Ash handling is a major problem for utilities and industrial owners using as a primary fuel. The firing concept used, that is, cyclone, pulverized coal, or fluidized bed firing, determines the type and characteristics of ash. Waste fly ash (fly ash and bottom ash) is generated in large volumes and
handling system. Therefore, the ash can be conveyed by means of a pneumatic conveying system to the final silo (Figure 7). A trial operation showed that mixed fly and bottom ash from a coal fued power plant can be reused as raw material for cement production [6]. By mixing the ash its disposal is simplified as the combined ash is sent to the
