Download and read online Rotary Kilns in PDF and EPUB 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. This new edition contains an updated CFD section with inclusion of recent case studies and in line with recent developments covers pyrolysis processes, torrefaction of biomass, application of rotary kilns in C02 capture and information on using rotary kilns as incinerators for hydrocarbons. Provides essential information on fluid flow, granular flow, mixing and segregation, and aerodynamics during turbulent mixing and recirculation Gives guidance on which fuels to choose, including options such as natural gas versus coal-fired rotary kilns Covers principles of combustion and flame control, heat transfer and heating and material balances New edition contains information on pyrolysis processes with low temperatures and torrefaction of biomass. It also covers calcination of petcoke, how rotary kilns are used as incinerators for chlorinated hydrocarbons. Includes updated material on CFD simulation of kiln gas and solids flow with a selection of recent case studies.

Download and read online The Coal Handbook Towards Cleaner Production in PDF and EPUB Coal remains an important fossil fuel resource for many nations due to its large remaining resources, relatively low production and processing cost and potential high energy intensity. Certain issues surround its utilisation, however, including emissions of pollutants and growing concern about climate change. The coal handbook: Towards cleaner production Volume 2 explores global coal use in industry. Part one is an introductory section which reviews the social and economic value of coal, emissions from coal utilisation, the handling, impact and utilisation of coal waste, and an exploration of emerging and future issues around industrial coal utilization. Chapters in part two highlight coal resources, production and use in established markets as well as the emerging markets of Brazil, the Russian Federation, India, Indonesia, and China. Part three focuses specifically on coal utilisation in industry. Chapters consider thermal coal utilisation, coal use in iron and steel metallurgy, advances in pulverised fuel technology, and the evaluation of coal for thermal and metallurgical applications. Further chapters explore coal utilisation in the cement and concrete industries, coal gasification and conversion, and value-in-use assessment for thermal and metallurgical coal. A final chapter summarises the anticipated future pathway towards sustainable, long-term coal use, suggesting transitions that will be needed to ensure cleaner utilisation for many decades to come.

Download and read online Used post consumer Tyres in PDF and EPUB Proceedings of the International Conference organised by the Concrete and Masonry Research Group and held at Kingston University - London at 14-15 September 2004 With the introduction of waste legislation, in the form of regulations and directives, in many parts of the world a significant move towards sustainable waste management is becoming a legal requirement. Emphasis is now being placed on increasing recycling and promoting more sustainable waste management practices, and greater co-ordination between the public, private and independent sectors, and all concerned with the management of waste and reusable materials. However, sustainable waste management entails complex technological, environmental, social, cultural and economic issues. This, together with technological advances in recycling, means the waste sector is facing enormous challenges in developing suitable waste management and recycling strategies. It is therefore necessary to share and explore existing expertise; to review and discuss the challenges in order to identify opportunities for improving waste management and recycling and promoting sustainable resource use.
