Compared to a global coal production of around 3.7 Gt in 1999, coal use in power and heat stations amounted to 2.3 Gt whereas the non-metallic minerals industry, which includes cement production, used only about 0.5 Gt (IEA, 2001). The ...

Coal is used as an energy source in cement production. Large amounts of energy are required to produce cement. Kilns usually burn coal in the form of powder and consume around 450g of coal for about 900g of cement produced. Coal combustion products (CCPs), such as Fly Ash also play an important role in cement manufacture and in the …

Cement Plants: Coke. Coal-derived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heat-up of the charge, the fuel's volatiles are lost without ...
