were produced in a total of 198 cement kilns at 118 plants in the United States in 1998.5 This was a 6.0 percent increase from the 1990 reported total production of 73.5 million metric tons. Cement industry annual clinker capacity steadily declined from the 1975 peak through 1990 and
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 ton-clinker per day. It was found that about 40% of the total input energy was being lost through hot flue gas (19.15%), cooler stack (5.61%) and kiln shell (15.11% convection plus radiation).
