  • Is `clean` coal possible?

    VANCOUVER, April 18, 2007 (GLOBE-Net) - Coal is the world’s most commonly used fuel to produce electrical energy, and will continue as such for some time. Yet it is one of the ’dirtiest’ of all fossil fuels. It is a major source of toxic air pollutants and the leading source of energy-related greenhouse gas emissions. Many believe ’clean coal’ technologies will improve the energy efficiency of ...

  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

  • New coal report underscores the urgent need for global clean energy development

    The latest International Energy Agency’s (IEA) Medium-Term Coal Market Report 2012 re-confirms the dangerous path the world is on–a path of increasing dependence on coal, which carries serious environmental risks for people and the planet. According to ...

  • Difficult Complex Decisions For Coal-fired Power Plant Operators

    Changing fuel prices, government regulations and technology all combine to make decision making difficult for operators and developers of coal-fired power generation facilities around the world. Power plant designers in developing countries face new local environmental regulations plus additional requirements stipulated by lenders such as the World Bank. In the developed world, the regulations ...

  • Closing the door on building new coal-fired power plants in America

    Community opposition, legal challenges, and financial uncertainty over future carbon costs are prompting companies to rethink their plans for coal. Since the beginning of 2007, 95 proposed coal-fired power plants have been cancelled or postponed in the United States--59 in 2007, 24 in 2008, and at least 12 in the first three months of 2009. This covers nearly half of the 200 or so U.S. coal-fired ...

  • A new way to measure emissions from China’s Coal-Fired Power Plants

    To prevent the most severe impacts of climate change, it is essential to limit fossil fuel use—particularly coal use in power production. The share of coal in global energy consumption is increasing, with ...

  • Nuclear power plant keeps intakes clean - case study

    When this nuclear power plant in the Great Lakes region needed reliable traveling water screens to keep it’s intakes clean, they chose International Water Screens. Vertical screens with hoods provide clean water to create steam to generate up to 725,000 kilowatts of electricity for the surrounding region. This project included: Traveling Screen(s) Elevator ...

  • Disposal of saline wastewater from electrical power plants

    Saline wastewater from a coal-fired Utah Power Plant has been applied in central Utah, USA, since 1987, to irrigate various agricultural crops. The primary goals of this research: to dispose of saline wastewater by maximising actual evapotranspiration (ETa) and to prevent contamination of surface and groundwater by eliminating runoff and throughout the years (1987-2005). Plots were established ...

  • Analysis of U.S. coal plant retirements case study

    In 2010, MJB&A completed a report for a major natural gas transmission company of coal-fired electricity generating units (EGUs) in several different geographic regions and their potential for retirement and/or to repower with natural gas. This analysis developed an indicative model of future coal-fired power plant repowerings and retirements based on a range of operational and market ...

  • Application of artificial neural network to exergy performance analysis of coal fired thermal power plant

    This study presents an artificial neural network (ANN) model to predict the exergy efficiency in a thermal power plant. An ANN model based on back–propagation learning algorithm for prediction of exergy efficiency was developed. In the ANN model, the actual data set includes 27 values, of which 18 values were used for training the network and 9 values, were selected randomly to test the ...
