  • Cleaning the Air We Breathe, Coal Fired Power Plant - Case Study

    By cleaning flue gases from coal power plants, the amount of environmentally hazardous emissions can be sharply reduced. Mist elimination from Munters is a critical part of this process. Munters has worked with leading power generating companies for decades and have through testing and follow up built an extensive parameter database and design tool to be able to adapt and optimize results based ...

  • Coal-fired power on the way out?

    The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

  • Comparison of employment potential of the coal and wind power industries

    Australia, one of the world's largest producers of coal, is used as a case study to compare the employment potential in the coal and wind power electricity generation industries. It is revealed that, as a result of automation, employment in the coal mining industry fell by 45% between 1987 and 2002. Moreover, as a result of the restructuring of the electricity industry as a whole, employment in ...

  • 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 ...

  • Underground Coal Gasification: Converting Unmineable Coal To Energy

    Currently, about 1.5 billion people –almost a quarter of the world’s population— are without electric power. The International Energy Agency estimates that world energy demand (for all forms of energy, including transportation fuels) will increase by 36 percent by 2035 and fossil fuels, such as coal, will continue to play a critical role in meeting this demand. What is ...

  • King Coal’s Climate Challenge

    Coal is emerging as a major topic of conversation at the United Nations climate-change negotiations currently taking place in Warsaw – and rightly so. Indeed, it is a discussion that the world needs to have. The latest findings of the ...

  • The alternative to coal in South Africa

    With a desperate need for dispatchable generation, South Africa should be readily embracing CSP as a low-carbon, sustainable, base load energy alternative. So why do its energy authorities remain unconvinced? This question has formed the subject of Part 2 of the CSP Today South Africa Guide. London, UK October 11 2011 Forget green energy: while most nations are concerned ...

  • 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 ...

  • Competing Coal Ash Proposals

    On May 4, 2010, the U.S. Environmental Protection Agency (EPA) issued its long-awaited proposal to manage coal ash – the byproduct of burning coal to generate power. The agency proposed two quite different approaches for regulating coal ash, somewhat to the consternation of critics, who had hoped for more stringent ...

  • Thermo-economic efficiency of low capacity coal-based power plants

    The method of estimation of thermo-economic factors, allowing the justification of the construction of low capacity coal-based power plants has been developed in the present paper. The C-curve method applied for thermo-economic analysis is used here for determination of the optimal ratio between specific exergetic and cost-performance factors. The results of the analysis show that for coal-based ...

  • U.S. Signals the end of public money for coal-fired power

    U.S. public financing for overseas coal-fired power is likely coming to an end. That’s the clear signal from the U.S. Department of Treasury’s announcement earlier this month. The Treasury Department provided new guidance for multi-lateral development banks’ ...

  • 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 ...

  • Utilisation of waste coal dust of steel industry for power generation

    The present paper describes the generation of waste coal-dust from steel industry and its utilisation for generation of power in power plant. The main objective of the work is to utilise the heat energy of coal dust into useful work and propose a combination of coal and coal dust supplying system to the boiler. The work started with the collection and analysis of the coal dust. The physical ...

  • Exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant

    This paper presents exergoeconomic analysis of a Kalina cycle coupled coal–fired steam power plant using specific exergy costing (SPECO) methodology. Cost–balance and auxiliary equations are developed and solved. The results indicate that in the topping cycle, the boiler and the turbine contribute maximum to the formation of product cost. High value of exergoeconomic factor for the boiler ...

  • Air Quality Permitting for a New Coal-Fired Power Plant: A Timeline

    The high price of natural gas and alternative fuels has made utility companies take a second look at coal as a cheap, plentiful fuel source. For a greenfield plant considering coal, the environmental considerations are significant but not insurmountable. This article discusses the air quality regulations and permitting requirements that must be addressed, from New Source Review to greenhouse gas ...
