Abstract
Rotary kilns are multipurpose reactors, in which take place chemical and physical reactions. These reactors are used in many processes involving conversion a solid charge by heat treatment. These systems have been investigated extensively to improve the mathematical description of dynamic behaviour. Most of the research work on this type of complex system is based on models with constant or inaccessible parameters. Therefore, this present study, at the basis of a phenomenological model, offers an approach to estimate the proposed state variables of a clinker rotary kiln. This estimation is done from a steady state condition of the kiln when the system inputs were stable. Furthermore, the identification procedure developed is devoted to calculate numerically all parameters of the model, and find an analytical representation of them. Yet due to the complexity of the phenomena taking place therein, developed a dynamic model is easy of access.
