Abstract: The production of cement can be done with different methods. Energy saving studies are important in cement production, in terms of both heat and electrical energy. In the current study, comparative energy and exergy analyses for specific clinker production were carried out on the essentially dry system, the serial flow four-stage preheater cyclone, the serial flow four-stage cyclone pre-calcination, and the parallel flow four-stage cyclone precalcination cement production methods. Moreover, the results calculated by entering these basic parametric values in a computer program developed to calculate mass balance, and energy and exergy analyses for cement production are shown in the form of tables. According to these values, we conclude that the lowest irreversibility rate occurs in the serial flow pre-calcination cement production method.

Keywords: energy analysis; exergy analysis; cement plants; serial flow; parallel flow; preheater cyclone; cyclone pre-calcination; clinker production; irreversibility.
