In the cement plant, the preheater system functions as heat exchanger. The hot gas generated in the kiln to burn the clinker leaves the kiln and moves up the pre-heater to heat up the raw meal falling vertically through the preheater system. The thermal energy cost of the cement manufacturing depends upon the heat exchange efficiency of the system.
