The cyclones (preheater) of LEBDA Cement Plant was taken in this research as case study. The aim of this study is to determine the actual burning efficiency of cyclones. In order to achieve the aim of this project, two samples taken from the preheater to be tested and analyzed, in order to determine the total efficiency of the preheater. Samples were analyzed for composition and encountered a sequent Loss on Ignition test (LOI) in order to identify the burning efficiency of the preheater units. Each sample exposed to the same tests as the other one. In addition, the temperatures profiles used in the Loss on Ignition tests were taken from two different sources. The first temperature profile (Actual Profile) was directly measured from the preheater units. Moreover, the second profile (Designing Profile) was taken from the plant manufacturer’s hand book. After the burning efficiency was determined, the results indicated the weak points in cyclones and the reasons for the quality and amount drop of the final product (The research point). Therefore, the results obtained can led to the final optimization, by fixing the weakness in the stages identified to increase the burning efficiency. Moreover, the optimum operating conditions for the preheater can be achieved (future research point).
