Book Description :

Low-rank coals for power generation and fuel production provides a thorough introduction to lignite (brown coal) and sub-bituminous 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

Book Description :

The importance of low quality coals has emerged in current years. A major strategic concern is that the rapid growth in hard coal production has resulted in a sharp fall in the reserves- to production ratios worldwide. As hard coals are depleting rapidly, the resulting price surge and supply risks are the key challenges facing many coal consuming countries. Moreover, coal market dynamics are also changing; this change in market dynamics has forced some coal importers to seek new sources of supply, with subbituminous coal having already begun to gain attention in world markets. Low quality coals thus have an important role to play in maintaining security of coal supply. In addition, since low quality coals are generally produced by surface mining, their production costs are much lower than hard coals that are extracted through underground operations. To this end, for instance, a number of high efficiency processes are under development in Australia, Germany, Japan and the USA. All these developments in power generation, CTL, UCG, drying and upgrading are likely to ensure a sustainable future for low quality coals. Low-rank Coals for Power Generation, Fuel and Chemical Production discusses the current status of utilization of low quality coals for power generation worldwide. It provides a comprehensive and systematic review of the properties of low-rank coals Power generation using low quality coals is dominated by Pulverised Coal Combustion (PCC) plants. Although the majority of PCC plants use subcritical technologies, a number of new plants have adopted supercritical steam conditions at large scale. This book will presents research results and reviews discussing the impact of coal characteristics, operational experience gained with low quality coals, and future trend of development. This book is a valuable information resource for power generation engineers and researchers seeking to maximize the opportunities provided by these cheaper coal feedstock for effective and eco-friendly power generation.

Book Description :

We are currently facing a global problem caused by increasing levels of greenhouse gases, mostly derived from fossil fuels, resulting in climate change. Communities want an affordable and secure supply of power alongside emissions reductions. Coal electricity generation offers a secure and affordable supply, but, currently, this comes with high emissions. This volume examines efforts by both industry and governments to develop a cleaner use of low rank coals. It presents leading research on creating affordable, high-quality fuel for efficient power generation, with a trajectory toward affordable zero-emissions production. This book will be of interest to organisations active in developing clean usage of coal and which conduct research on low emissions power. It will also contribute to policy development of low-, and zero-emissions coal power generation, particularly in regions with abundant deposits of low-cost brown coal, lignite, and subbituminous coal, including the US, China, Europe, India, Indonesia, and Australia.

Book Description :

Fifteen leading scientists active in research on the chemistry, microbiology, enzymology, and genetics of coal biotransformation summarize knowledge of the mechanisms by which bacteria and fungi metabolize the macromolecular structure of lignite coals. They also explore the potential for developing commercially viable biotransformations of low rank coals into useful chemicals and clean-burning liquid and gaseous fuels. Microbial Transformations of Low Rank Coals reviews the types of aerobic and anaerobic microbes known to transform fuel and discusses the relative potential of aerobic versus anaerobic organisms. Biochemical mechanisms used by microorganisms to solubilize, depolymerize, liquify, and gasify coal are examined. The book also reviews the potential for using microorganisms to remove organic sulfur from coal and the potential for using genetic engineering to improve coal biotransforming microorganisms.

Book Description :

The U.S. Department of Energy (DOE) National Energy Technology Laboratory Office of Coal and Environmental Systems has as its mission to develop advanced gasification-based technologies for affordable, efficient, zero-emission power generation. These advanced power systems, which are expected to produce near-zero pollutants, are an integral part of DOE's Vision 21 Program. DOE has also been developing advanced gasification systems that lower the capital and operating costs of producing syngas for chemical production. A transport reactor has shown potential to be a low-cost syngas producer compared to other gasification systems since its high-throughput-per-unit cross-sectional area reduces capital costs. This work directly supports the Power Systems Development Facility utilizing the KBR transport reactor located at the Southern Company Services Wilsonville, Alabama, site. Over 2800 hours of operation on 11 different coals ranging from bituminous to lignite along with a petroleum coke has been completed to date in the pilot-scale transport reactor development unit (TRDU) at the Energy & Environmental Research Center (EERC). The EERC has established an extensive database on the operation of these various fuels in both air-blown and oxygen-blown modes utilizing a pilot-scale transport reactor gasifier. This database has been useful in determining the effectiveness of design changes on an advanced transport reactor gasifier and for determining the performance of various feedstocks in a transport reactor. The effects of different fuel types on both gasifier performance and the operation of the hot-gas filter system have been determined. It has been demonstrated that corrected fuel gas heating values ranging from 90 to 130 Btu/scf have been achieved in air-blown mode, while heating values up to 230 Btu/scf on a dry basis have been achieved in oxygen-blown mode. Carbon conversions up to 95% have also been obtained and are highly dependent on the oxygen-coal ratio. Higher-reactivity (low-rank) coals appear to perform better in a transport reactor than the less reactive bituminous coals. Factors that affect TRDU product gas quality appear to be coal type, temperature, and air/coal ratios. Testing with a higher-ash, high-moisture, low-rank coal from the Red Hills Mine of the Mississippi Lignite Mining Company has recently been completed. Testing with the lignite coal generated a fuel gas with acceptable heating value and a high carbon conversion, although some drying of the high-moisture lignite was required before coal-feeding problems were resolved. No ash deposition or bed material agglomeration issues were encountered with this fuel. In order to better understand the coal devolatilization and cracking chemistry occurring in the riser of the transport reactor, gas and solid sampling directly from the riser and the filter outlet has been accomplished. This was done using a baseline Powder River Basin subbituminous coal from the Peabody Energy North Antelope Rochelle Mine near Gillette, Wyoming.
