The heating process in the cement kiln requires intense energy to heat the clinker and compensate for the heating loss. Studies illustrate a significant loss of energy (> 50 %) in cement kilns, as shown in Fig. 2 [4]. Thus, there is a need for optimal design and efficient operation of the cement kiln to minimise this energy loss.
