Dynamic Model for Simulation and Control of Cement Rotary,
A dynamic mathematical model was developed for the simulation and control of cement rotary kilns. The model consists of a set of nonlinear partial differential equations, and represents the material and energy balances in the kiln. Based on some logical assumptions, the model does not only consider the reaction mechanisms but also reduces the complexity of computer simulation.CFD MODELING OF A CEMENT KILN WITH MULTI CHANNEL,temperature, and gas components in a cement rotary kiln were obtained by numerical simulation of a 3000 t/d rotary kiln with a four-channel burner. A zone wise heat flux model was presented which accounted for the thermal enthalpy of the clinker formation process and gave more insight to fluid flow, temperature, etc. within the cement rotary kiln.Experience with the SIMULEX Cement Plant Training Simulator,several types of cement are also simulated. The simulator only allows the kiln system and the cement grinding plant to be operated if sufficient raw meal, pulverized coal and clinker are available in the silos. 2.3.1 Raw meal grinding plant The raw mill is designed as a roller mill with integral caged-rotor classifier (Fig. 5).
