Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
Energy consumed during the clinker formation process is calculated to obtain the general energy balance of the system. A summary for kiln energy balance analysis is presented below: Energy consumption in formation of clinker is calculated to obtain general energy balance of kiln. Energy is transferred by heat, mass, work inside the rotary kiln.
Bypass dust leaving the kiln system requires separate reporting: line022; CKD recycling remains within the mass balance. Thus, it does not need additional reporting. The mass flow of CKD Cement kiln dust leaving the kiln system (and crossing the red boundary in the diagram) needs to be accounted for additionally: line023.
C. Energy Balance in the Grate Cooler The main function of cooler is to cool the clinker and transfer the energy to air. The clinkers are losing heat by conduction and convection to the cooling air coming from fan below the clinker bed. This air is then use as a secondary or tertiary in kiln preheater respectively. The cooler is in continuous

3 EVERY THING YOU NEED TO KNOW ABOUT HEAT BALANCE IN CEMENT KILN. "Where does all that heat go?" Heat balances are the foundation for an engineer to identify the opportunities for possible heat savings. There are several areas where heat could possibly be saved to make a kiln operate more efficiently in matters of energy consumption.
