Low Rank Coals For Power Generation Fuel And Chemical Production

Book Description :

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

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.

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 :

Skyrocketing energy costs have spurred renewed interest in coal gasification. Currently available information on this subject needs to be updated, however, and focused on specific coals and end products. For example, carbon capture and sequestration, previously given little attention, now has a prominent role in coal conversion processes. This book approaches coal gasification and related technologies from a process engineering point of view, with topics chosen to aid the process engineer who is interested in a complete, coal-to-products system. It provides a perspective for engineers and scientists who analyze and improve components of coal conversion processes. The first topic describes the nature and availability of coal. Next, the fundamentals of gasification are described, followed by a description of gasification technologies and gas cleaning processes. The conversion of syngas to electricity, fuels and chemicals is then discussed. Finally, process economics are covered. Emphasis is given to the selection of gasification technology based on the type of coal fed to the gasifier and desired end product: E.g., lower temperature gasifiers produce substantial quantities of methane, which is undesirable in an ammonia synthesis feed. This book also reviews gasification kinetics which is informed by recent papers and process design studies by the US Department of Energy and other groups, and also largely ignored by other gasification books. • Approaches coal gasification and related technologies from a process engineering point of view, providing a perspective for engineers and scientists who analyze and improve components of coal conversion processes • Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes • Emphasizes the importance of the coal types fed to the gasifier and desired end products • Covers gasification kinetics, which was largely ignored by other gasification books Provides a perspective for engineers and scientists who analyze and improve components of the coal conversion processes Describes the fundamentals of gasification, gasification technologies, and gas cleaning processes Covers gasification kinetics, which was largely ignored by other gasification books

Book Description :

Three fossil fuels – coal, oil and gas supply over 80% of the global primary energy requirements and, in spite of concerns about environmental pollution, the dominance of fossil fuels in the world’s energy mix is unlikely to change very much in the foreseeable future. Coal, the highest pollutant of them all fuels over 40% of the global electric power generation and, while considerable effort is being made to diversify to less anthropogenic fuels , various projections show that there will be little change for many years. Most of the increase in power generation in the next few decades will be accounted for by emerging countries and, for many, coal is the only available or affordable source of primary energy. Also, some developed countries depend on coal for up to 90% of power generation. The contribution of cleaner energies (solar, wind, biofuels, etc.), to the global primary energy mix is not likely to exceed 10% in the next two or three decades and it is now widely accepted that the only feasible option in the foreseeable future is to ‘clean-up’ coal. For over fifty years Nigeria depended on coal for over 70% of primary energy requirements but, with the discovery of oil and gas in early 1960s the demand for coal began to decline. However, in view of perpetual and intractable problems with gas supply and the hydrodams, there has been renewed interest in the country’s vast coal resources and many coal-fired power plants are scheduled to come on stream by 2020. It is noteworthy that all the proposed plants will adopt clean coal technologies.

Book Description :

Oxy-fuel combustion is currently considered to be one of the major technologies for carbon dioxide (CO2) capture in power plants. The advantages of using oxygen (O2) instead of air for combustion include a CO2-enriched flue gas that is ready for sequestration following purification and low NOx emissions. This simple and elegant technology has attracted considerable attention since the late 1990s, rapidly developing from pilot-scale testing to industrial demonstration. Challenges remain, as O2 supply and CO2 capture create significant energy penalties that must be reduced through overall system optimisation and the development of new processes. Oxy-fuel combustion for power generation and carbon dioxide (CO2) capture comprehensively reviews the fundamental principles and development of oxy-fuel combustion in fossil-fuel fired utility boilers. Following a foreword by Professor János M. Beér, the book opens with an overview of oxy-fuel combustion technology and its role in a carbon-constrained environment. Part one introduces oxy-fuel combustion further, with a chapter comparing the economics of oxy-fuel vs. post-/pre-combustion CO2 capture, followed by chapters on plant operation, industrial scale demonstrations, and circulating fluidized bed combustion. Part two critically reviews oxy-fuel combustion fundamentals, such as ignition and flame stability, burner design, emissions and heat transfer characteristics, concluding with chapters on O2 production and CO2 compression and purification technologies. Finally, part three explores advanced concepts and developments, such as near-zero flue gas recycle and high-pressure systems, as well as chemical looping combustion and utilisation of gaseous fuel. With its distinguished editor and internationally renowned contributors, Oxy-fuel combustion for power generation and carbon dioxide (CO2) capture provides a rich resource for power plant designers, operators, and engineers, as well as academics and researchers in the field. Comprehensively reviews the fundamental principles and development of oxy-fuel combustion in fossil-fuel fired utility boilers Provides an overview of oxy-fuel combustion technology and its role in a carbon-constrained environment Introduces oxy-fuel combustion comparing the economics of oxy-fuel vs. post-/pre-combustion CO2 capture
