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 material mainly because during the gradual heat-up of the charge the fuel& 39;s volatiles are lost without ignition so wasting up to half the fuel& 39;s calorific value. Burning coal
