Abstract

CEMENT ROTARY KILNs are extensively used to change raw material into clinker. Complex phenomenon is observed in CEMENT ROTARY KILNs resulting from conduction, convection and radiation heat transfer, interactions between bed materials and hot gas flow and kiln rotation. Therefore, the modeling of CEMENT ROTARY KILN have difficulty due to non-linear and stiff set of equations. Regards to over prediction of the maximum inner temperature of the kiln in SPANG MODEL; a one dimensional, steady state model is developed based on SPANG MODEL to investigate the operation of a cement kiln. In the present work, temperature distribution of hot gases is predicted using two-step methane kinetic to calculate the heat of combustion. Since the amount of CO2 emission in cement kiln processes is very important, CO2 emission generated by both bed material reactions and combustion process are calculated and compared. Modeling results showed that approximately half of CO2 emission is in result of combustion process and other one is from bed material reactions.
