The long-term future for coal looks bleak. The recent UN climate change conference in Paris called for an end to the use of fossil fuels. However, coal remains one of the world's most important sources of energy, fuelling more than 40% of electricity generation worldwide, with many developing nations relying almost wholly on coal-fuelled electricity. Coal has been the fastest growing energy source in recent years and is essential for many industrial activities, but the coal industry is hugely damaging for the environment. A major driver in climate change and causing around 40% of the world's carbon dioxide emissions, coal fuel comes at a high environmental price. Furthermore, mining and air pollution kill thousands each year. A timely addition to the series, this book critically reviews the role of coal in the 21st century, examining energy needs, usage and health implications. With case studies and an examination of future developments and economics, this text provides an essential update on an environmental topic the world cannot ignore.

This book analyzes the continuous operation of a power plant with condensing power units in combined heat and power mode (CHP-mode) over a period of one year. Focusing on the operation of one and two power-unit systems with differing heat exchanger configurations, this book uses mathematical modeling of the steam-water cycle of a 370 MW power unit to calculate the operating characteristics and mass-energy balance of the system.Featuring comprehensive thermodynamic analysis of the quasi-unsteady operation of power units in cogeneration for electrical power generation, as determined by the Polish Power System, this work also includes an economic analysis of the power plant, presenting the costs and economic effectiveness of such a system.

Coal has long been the major fossil fuel used to produce electricity. However, coal-fired electric power plants are one of the largest sources of air pollution in the United States, with greenhouse gas (GHG) emissions from the burning of fossil fuels believed to be the major contributor to global climate change. Regulations under development at the Environmental Protection Agency (EPA) would impose new requirements on fossil-fueled (mostly coal-fired) power plants (CFPPs) to control GHG emissions. This book focuses on efficiency improvements to power plants, and discusses retrofits, technologies, and other modifications to facility operations which offer the potential to improve power plant efficiency and reduce CO2 emissions.

Concern over the effects of airborne pollution, green house gases, and the impact of global warming has become a worldwide issue that transcends international boundaries, politics, and social responsibility. The 2nd Edition of Coal Energy Systems: Clean Coal Technology describes a new generation of energy processes that sharply reduce air emissions and other pollutants from coal-burning power plants. Coal is the dirtiest of all fossil fuels. When burned, it produces emissions that contribute to global warming, create acid rain, and pollute water. With all of the interest and research surrounding nuclear energy, hydropower, and biofuels, many think that coal is finally on its way out. However, coal generates half of the electricity in the United States and throughout the world today. It will likely continue to do so as long as it's cheap and plentiful [Source: Energy Information Administration]. Coal provides stability in price and availability, will continue to be a major source of electricity generation, will be the major source of hydrogen for the coming hydrogen economy, and has the potential to become an important source of liquid fuels. Conservation and renewable/sustainable energy are important in the overall energy picture, but will play a lesser role in helping us satisfy our energy demands today. Dramatically updated to meet the needs of an ever changing energy market, Coal Energy Systems, 2nd Edition is a single source covering policy and the engineering involved in implementing that policy. The book addresses many coal-related subjects of interest ranging from the chemistry of coal and the future engineering anatomy of a coal fired plant to the cutting edge clean coal technologies being researched and utilized today. A 50% update over the first edition, this new book contains new chapters on processes such as CO2 capture and sequestration, Integrated Gasification Combined Cycle (IGCC) systems, Pulverized-Coal Power Plants and Carbon Emission Trading.

The present thesis is set out to assess the potential of a novel and innovative approach for the recovery of energy from municipal solid waste, in the following referred to as the UPSWING concept. This (theoretical) concept describes the coupling of a waste incinerator with a conventional power plant, both on the steam- and on the flue gas side. The waste flue gases are pre-cleaned prior to injection into the power plant process in order to keep substances, potentially harmful for the environment as well as for the power plant process, away from the power plants'boiler system. The concept proposes significant benefits in terms of efficient waste-to-energy conversion, but also towards the required investment costs, which are expected to be considerably lower compared to a same-sized municipal solid waste incinerator. The demand for such advanced concepts is given by European Legislation, setting strict rules on landfill disposal of untreated municipal solid waste, while promoting more environmentally friendly and more efficient waste treatment concepts under the framework of the Community Waste Strategy COM(96) 399. In this thesis the environmental, operational and economic performance of the UPSWING concept is evaluated by means of a process comparison with other state-of-the-art concepts. In this context, conventional municipal solid waste incineration and direct co-combustion of waste-derived fuels in thermal power plants have been considered. Environmental and operational aspects were investigated by experimental and theoretical means, while the economical aspects were theoretically assessed by a comparison of the anticipated costs for waste treatment. Following this approach, it was possible to identify benefits respectively deficits of the different waste treatment concepts investigated within the scope of this thesis. In essence, it was found that the UPSWING process is capable to maintain the high environmental standards of municipal solid waste incineration. In terms of process efficiency and necessary investment costs, significant benefits compared to a standalone waste incinerator were found, while restrictions and potential problems could be determined in terms of waste flue gas and steam integration. Nevertheless, the UPSWING process proposes significant advantages and a large-scale demonstration of the process could be the next step to evaluate its overall capabilities.
