Book Description
This article presents a one-dimensional mathematical model to simulate the lime-burning process in normal shaft kilns. The model comprises ordinary differential equations derived from the principal conservations of mass and energy. A shrinking core approach is employed to describe the mechanisms and to calculate the decomposition rate of limestone particles. The model is used to simulate the temperature of the gas and the solid, the lime-burning degree, the pressure drop, and the heat loss by kiln shell. Operating conditions, such as kiln throughput, energy consumption, and stone size, are also investigated by the model. Experiments were carried out to measure temperatures in industrial kilns. Maximum temperatures were observed in the region of 1.0-2.0 m above the burner level. The kiln temperature is about 1600°C. Comparisons of the experiments and simulations show that the temperatures measured in the kilns are very close to the solid temperatures predicted by simulations. The results of simulations and those of experiments are in good agreement. The results of this study can be direct utility for the regulation and optimization of industrial lime shaft kilns.

Book Description
- Modern uses of traditional materials - 'Lime and Limestone' is a comprehensive and up-to-date presentation of the main scientific and technological aspects of the quarrying, processing, calcining and slaking of lime and limestone products. It places emphasis on how the processes are designed to ensure that the products meet market requirements and comply with customer specifications. It describes authoritatively, and in detail, the current uses in the many market segments, including: - iron, steel and other metals, - building, construction and cement, - water, sewage and environmental protection, - chemicals, agriculture and foodstuffs. It also addresses topical issues such as: environmental protection measures within the industry, toxicology, occupational health, storage, transportation, economic aspects, sampling, testing and analysis. The book maintains a good balance between scientific information - of use to technologists - and more general information - of value to production and commercial personnel, both within the lime and limestone industries and in the many industries that they serve.

Book Description
The Small Scale Vertical Shaft Lime Kiln covers in depth the design, construction, and operation of a particular type of lime kiln: a continuous, natural draught, mixed feed, vertical shaft kiln (VSK). The manual focuses on 'small-scale' production and is aimed at lime-burners, technologists and fieldworkers in developing countries, as well as those interested in burning lime on any scale.

Book Description
Full scale calcination of high calcium limestone using traditional methods was performed in the batch process Experimental Lime Kiln (ELK). The ELK is equipped to monitor temperature, air flow and gas compositions and also has significant insulation to ensure minimum lateral energy loss during burning. Internal kiln wall temperatures of up to 550°C, and kiln core temperatures of 850°C, within the range of calcium carbonate disassociation have been achieved for several hours with predictable temperature/time gradients. A mixed feed solid fuel : stone ratio of 1:9 was employed resulting in limestone conversion to quicklime of 75% ± 9. The heat balance efficiency is approximately 45%. However, this may not be a useful indicator of overall efficiency of binder production, especially in a open-top batch process traditional kiln. The hydration behaviour of the low-temperature traditional quicklime is more varied than high-temperature commercially produced quicklime, made from the same stone. The low temperature material hydrates more slowly, reaches a lower temperature and maintains a peak temperature plateau for longer than the high-temperature quicklime. The traditional quicklime also produces as much as 50% non-hydrated residue during the tests. This suggests an origin for "lime inclusion" texture in historic mortars. Mortars produced using traditional hot mixing processes are petrographically similar to historic mortars. The recognition of distinctive quicklime microstructures may also provide a diagnostic tool for quality control in small-scale traditional lime production.
