Mathematical modelling of the cement clinker burning process
The joint model for the clinker burning process is based on energy and material balances and consists of individual models for the plant components, namely preheater, calciner, bypass, rotary kiln and grate cooler. The modular design allows adapting it comparatively easily and flexibly to different cement plants. By taking into account material as well as process engineering and plant processes the clinker burning process can be calculated close to practice. The results are in agreement with the present understanding of the process. However, they can only be verified in individual cases as it is not yet possible to make sufficiently accurate measurements in all areas of the kiln plant. Improvements to the model are needed, especially with respect to the material processes. From the energy point of view these processes can be comparable with plant and process engineering factors and must therefore not be neglected in the energy and mass balances. They are also important with respect to clinker quality and environmental protection. Even in its present state the model can be used to carry out theoretical investigations of changes in a plant in advance. With a procedure analogous to that used in this work the changes can be assessed by comparison of the calculation for a reference condition with the calculated results for the modified plant. At present this primarily concerns energy and material questions such as a changed mode of operation, the use of secondary materials, and plant modifications. This will be extended in the future to cover emissions as part of a research project.
