Abstract
Kiln systems are used industrially for processes such as cement production and incineration. This modeling work of the heat control in kiln system was established for further improvement in the kiln control. The system model was established on the principle of mass/heat transfer and on the knowledge of the kinetics of reactions that takes place in the kiln. Data used in the system model was obtained from Dangote cement, Ibese in Nigeria. It was seeing that Fuzzy-PID gave a lower overshoot of 9.6% and a settling time of 0.11sec, compared to that of Cohen-Coon-PID (CC-PID), which gave a higher overshoot of 11.60% and a settling time of 0.129sec. The mathematical modeling gave the better performance for burning zone temperature control of the cement rotary kiln using Fuzzy-PID controllers due to its low overshoot and smaller settling time compared to the CC-PID controllers. This mathematical modeling could be used in cement rotary kiln control system.
