Available in PDF, EPUB and Kindle. Book excerpt: Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

Available in PDF, EPUB and Kindle. Book excerpt: The negative environmental impacts of energy use, particularly soil and water pollution, continue to present serious policy dilemmas. The release of emissions and effluents and the build-up of solid waste throughout the fuel cycle have disruptive effects on natural habitats and human health. Further, fuel combustion can result in the emission of carbon dioxide, ozone, methane and nitrogen dioxide the 'greenhouse gases' which have been linked to climate change. The safe and sustainable use of energy has become an important issue in the wider environmental debate. In this report, researchers from the Stockholm Environment Institute explore the issues raised by the use of low-grade fuels such as peat, wood, biomass, lignite, oil shale and municipal and industrial wastes. The present strategies and policy options for all stages of the process, from mining and transport to processing and combustion. With those who would like to learn more about these fuels in mind, the material is presented clearly, and discussions of environmental protection measures are given in table form throughout the ease of reference. A directory of environmental guidelines, regulations and standards is given in an appendix. While a high calorific value fuels remain the most significant source of energy in many countries, economic and other constraints on the use of these fuels may result in more nations turning to low-grade sources of energy to operate their industrial or transportation sectors. The greater potential for environmental degradation that accompanies the use of low-grade fuels means that it is crucial that environmentally sound methods for their management, such as those presented here, be more widely available. The Environmental Management of Low-Grade Fuels will be valuable for industry specialists, policy makers, students and all who are concerned with the life cycle of these materials.

Book excerpt: 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.

This book was released on 2017-06-22 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 circulatingfluidized 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.

Available in PDF, EPUB and Kindle. Book excerpt: Low-rank coals - lignite and subbituminous - are those which have been subjected to the least amount of metamorphic change during the coal-forming process. As such, they retain greater fractions of moisture and volatile matter from the original peat material, and contain less fixed carbon, than the high-rank coals - bituminous and anthracite. The primary measure used to classify the lower ranks of coal is heating value. Other important characteristics which distinguish the low-rank coals from high-rank coals are discussed in this report. Low-rank coals represent a major, and largely untapped, energy resource for this country. Very extensive deposits of lignite and subbituminous coal exist in the western states, the Gulf coast, and Alaska. Major deposits of low-rank coal are also found in many other countries, most notably the USSR, Australia, Canada, and the central and eastern European nations. Worldwide coal statistics indicate that low-rank coals account for roughly one-third of the total resource and current production tonnages. This report recommends a comprehensive national research, development, and demonstration (RD and D) program to enhance the development of low-rank coals. The major conclusion of this study is that the unique properties of these coals affect the technologies for their extraction, preparation, direct use, and conversion and justify a separate focus on low-rank coals in the national RD and D efforts.

Book excerpt: Coal fuels about 50 percent of US electricity production and provides a quarter of the country's total energy. China and India's ferocious economic growth is based almost entirely on coal-generated electricity. Coal currently looks like a solution to many of our fast-growing energy problems. However, while coal advocates are urging full steam ahead, increasing reliance on the dirtiest of all fossil fuels has crucial implications for the global climate, energy policy, the world economy, and geopolitics. Drawbacks to a coal-based energy strategy include: Scarcity - new studies suggest that the peak of world coal production may actually be less than two decades away. Cost - the quality of produced coal is declining, while the expense of transport is rising, leading to spiraling costs and increasing shortages. Climate impacts - our ability to deal with the historic challenge of climate change will hinge on reducing our coal consumption in future years. Blackout goes to the heart of the tough energy questions that will dominate every sphere of public policy throughout the first half of this century, and is a must-read for planners, educators, and anyone concerned about energy consumption, peak oil and climate change.
