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.
Electrical energy only comprises between 10 and 15% of the overall energy demand for cement production but is a notable cost driver [4], [5].Over the last decades the average specific electrical energy consumption has decreased (Fig. 3) [6].However, there are counteracting effects: CO 2-emissions can be significantly reduced by the increased …
