Thermal energy consumption and its conservation for a cement

The consumption of the energy in the cement plant is mainly due to raw mill, cooler, pre-heater and rotary kiln [14]. The total energy loss of the plant is generally accounted for about 35-39% of the total energy input [15]. This energy loss is due to the loss from the exhaust gas, cooler and the radiation heat transfer from the kiln cell.
