limestone calcination in a rotary kiln

Modeling and Simulation of Limestone Calcination in Rotary Kilns

M. Martins, A. S. Franca Published 2000 Engineering A one-dimensional mathematical model was developed for the simulation of limestone calcination in rotary kilns. The model is comprised of ordinary differential equations derived from mass and energy conservation principles. The system of equations is solved by a fourth-order Runge-Kutta method.
