    Minimum Calorific Value for Energy Recovery in Cement Kilns

    Cement kilns use counter-current flow for exchange of heat energy from the process gases to the raw material. There are four important stages in the process of manufacturing cement. The first stage is the heating of the raw material to about 900C. At this temperature the second stage begins which is a chemical reaction called calcination.
