Mathematical Modeling of Clinker Phases and Study of Effective Parameters in Steady-State .

Cement kiln is as the heart of the cement plant in clinker production that gas and solid materials are in contact with each other in countercurrent flow. In this study, a mathematical model of concentrations distribution and clinker phases according to the mass equations and kinetics of chemical reactions in the furnace length were studied. In steady state investigated Modeling whit coating effect and maintaining the property of physical and chemical. The role of effective parameters such as Composition of feed, temperature, activation energy, material flow rate, cross section and rotational speed of kiln investigated on the governing equations and models and these equations solved in steady-state using software Matlab-7. The results of the model were compared with the experimental data that good agreement are between predicted by the model and experimental data and an error of less than 3% for the data obtained from the model and experimental is the acceptable answer for model validation.
