Modeling full-scale lime kilns
Rotary lime kilns are widely used in the chemical process and metallurgical industries. Since most kiln processes are energy-intensive, there is a great incentive for these industries to optimize energy use. This requires knowledge of kiln parameters and understanding of the complex phenomena that occurs inside the kiln. However, the hostile environment of the kiln prevents direct observation or measurement within the kiln. Therefore, numerical modeling of the process is desirable. A numerical model of a full-scale lime kiln has been developed using a commercial CFD package, FLUENT. This model simulates turbulent gas flow and combustion of natural gas in the kiln gas, calcination of calcium carbonate to calcium oxide within the solid lime bed, and heat transfer mechanisms within and between the kiln gas and bed. The modeling results were obtained for different operating conditions.
