Low Rank Coal Technology

Low-Rank Coals for Power Generation, Fuel and Chemical Production provides a thorough introduction to lignite (brown coal) and subbituminous coals and explores how they can be used efficiently and economically in place of hard coal. The book examines the undesirable characteristics of low-quality coals, such as high moisture content, low calorific value, and aggressive ash characteristics, and the resulting refinements to standard technologies and practices required for successful combustion, gasification, and pyrolysis. The first part of this book provides a comprehensive and systematic review of the properties of low-rank coals and corresponding preparation methods, such as drying, cleaning, and upgrading. Power generation from low-rank coals is the focus of Part 2, with chapter topics ranging from high efficiency pulverized coal combustion and circulating fluidized bed combustion to emerging areas such as chemical looping and oxyfuel combustion. The final contributions address the important subjects of coal-to-liquids,polygeneration and coke production using low-rank coals, as well as the critical issue of carbon capture and storage. This book is a valuable resource for power generation engineers and researchers seeking to maximize the opportunities provided by these cheaper coal feedstocks for efficient and environmentally compatible power generation. Presents the most in-depth treatment of low-rank coals available Addresses both power generation and fuel production Includes coverage that spans pulverized coal combustion and emerging technologies, such as CFBC, UCG, CLC, and oxyfuel combustion

Low-Rank Coal Applications in Agriculture explores the commercialization and marketing potential of low-rank coal, which is rich in organic matter and humic substances. The author—a noted expert on the topic—clearly shows from a practical perspective, that rather than using it as an energy source, this material can be applied for the agricultural sector. The author investigates low-rank coal’s potential as used in dry and liquid humic products. This book discusses both raw materials and commercial products, and provides data on improved soil quality, crop yields, and livestock productivity. This groundbreaking book: details how this material can benefit agriculture; thus positioning coal in the more “green sector” type of industry presents original data collected from laboratories and agricultural fields, and summarizes literature on the science and regulation of low-rank coal and humic substances Written for field practitioners, end users, marketers, operators, regulators, researchers, and academics, Low-Rank Coal Applications in Agriculture is the first book on the market to explore the real-life use of low-rank coal for the agricultural sector.

This book gathers the proceedings of the 8th International Symposium on Coal Combustion. The contributions reflect the latest research on coal quality and combustion, techniques for pulverized coal combustion and fluidized bed combustion, special issues regarding CO2 capture (CCS), industrial applications, etc. – aspects that are of great importance in promoting academic communications between related areas and the technical development of coal-related fields. The International Symposium on Coal Combustion (ISCC), sponsored and organized by Tsinghua University since 1987, has established itself as an important platform allowing scientists and engineers to exchange information and ideas on the science and technology of coal combustion and related issues, and to forge new partnerships in the growing Chinese market. Researchers in the fields of clean coal combustion, carbon dioxide capture and storage, coal chemical engineering, energy engineering, etc. will greatly benefit from this book.
