Rotary Kilns Book Review:

Rotary Kilns—rotating industrial drying ovens—are used for a wide variety of applications including processing raw minerals and feedstocks as well as heat-treating hazardous wastes. They are particularly critical in the manufacture of Portland cement. Their design and operation is critical to their efficient usage, which if done incorrectly can result in improperly treated materials and excessive, high fuel costs. This professional reference book will be the first comprehensive book in many years that treats all engineering aspects of rotary kilns, including a thorough grounding in the thermal and fluid principles involved in their operation, as well as how to properly design an engineering process that uses rotary kilns. Chapter 1: The Rotary Kiln Evolution & Phenomenon Chapter 2: Basic Description of Rotary Kiln Operation Chapter 3: Freeboard Aerodynamic Phenomena Chapter 4: Granular Flows in Rotary Kilns Chapter 5: Mixing & Segregation Chapter 6: Combustion and Flame Chapter 7: Freeboard Heat Transfer Chapter 8: Heat Transfer Processes in the Rotary Kiln Bed Chapter 9: Mass & Energy Balance Chapter 10: Rotary Kiln Minerals Process Applications ·Covers fluid flow, granular flow, mixing and segregation, and aerodynamics during turbulent mixing and recirculation ·Offers hard-to-find guidance on fuels used for rotary kilns, including fuel options such as natural gas versus coal-fired rotary kilns ·Explains principles of combustion and flame control, heat transfer and heating and material balances

The Rotary Cement Kiln Book Review:

Structured into fourteen chapters, this volume covers various aspects of kiln maintenance and deals with the wear of components, operational parameters and their impact on the condition of the kiln, maintenance-friendly design considerations of kiln components, on-line techniques for condition monitoring, repair during operation, effective management of a kiln shutdown, and some management approaches. It presents systematic analyses of the problems encountered during the life span of the kilns and suggests appropriate method(s) to tackle them and meet the needs of engineers and operators involved. Written in simple language, containing a good blend of theory and practice, and supported with practical reference tables and figures, this book is intended for engineers, operators and maintenance workers working with cement kilns. The author, Dr. J.P. Saxena is an absolute expert in the field.

Limestone Sorbent Regeneration in Externally Fired Rotary Kilns Book Review:

Externally fired rotary kilns were evaluated for use as regeneration reactors for the spent limestone sorbent from a fluid-bed combustor. Coke and spent sorbent containing approximately 8 wt % sulfur were reacted at temperatures between 960 and 1060/sup 0/C in two laboratory-scale externally fired rotary kilns to produce lime sorbent suitable for reuse, and concentrated SO/sub 2/. It was possible to achieve a high percent of sorbent regeneration, but the SO/sub 2/ concentration in the off-gas was low. Different operating conditions were required to produce a higher concentration of SO/sub 2/ in the off-gas, and under these conditions, the percent of sorbent regeneration was low. Two empirical equations and the shrinking-core reaction-rate model were examined for application to the experimentally determined kinetic data. The shrinking-core model appeared to fit the data better than the empirical equations, and could be a useful predictor of the conversion of sulfated limestone and of the SO/sub 2/ concentration in the off-gas from a rotary-kiln regenerator. The materials used in the construction of one of the laboratory kilns were typical of commercially available production-size rotary kilns that are externally fired. However, the materials of construction were not sufficiently durable to withstand the high SO/sub 2/ concentrations and high temperatures involved in this reaction.
