Abstract: The numerical simulation was used to analyze Albania TITAN project, a 3300 t/d new dry-process cement clinker production line with a ? 4.4m×65m rotary kiln, which was completed by CBMI. Mathematical models were established for the kiln coating, refractory bricks, castables and kiln shell and heat transfer among these parts were simulated. The results show that a thicker kiln coating results in a lower temperature of the kiln shell and a less heat loss. The kiln shell surface temperature on both sides of tire No.2 is higher than that of tire No.3, therefore the air flow of cooling fans should be increased properly for tire No.2 to avoid tire deformation and severe thermal expansion. The kiln shell surface temperature near tire No.2 at the kiln inlet side is higher, thus adding two cooling fans is suggested. The number of cooling fans should be reduced appropriately to reduce the power consumption when the coating thickness remains stable during a period of normal and continuous production. It is found that 720 kWh of electricity can be saved per day when four shell cooling fans are turned off.
