This paper deals with the energy audit analysis of a dry type rotary kiln system working in a cement plant in Turkey. The kiln has a capacity of 600 tonclinker per day. It was found that about 40% of the total input energy was being lost through hot flue gas (%), cooler stack (%) and kiln shell (% convection plus radiation).
