  • Coal-to-liquid fuels poised for a comeback

    Converting coal into liquid fuels is known to be more costly than current energy technologies, both in terms of production costs and the amount of greenhouse gases the process emits. Production of coal-to-liquid fuel, or CTL, has a large carbon footprint, releasing more than twice the lifecycle greenhouse gases of conventional petroleum fuels. However, with the rise in energy prices that began ...

  • 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 ...

  • 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 ...

  • Composition, morphology, properties of coal fly ash microspheres and their application for conditioning liquid radioactive waste

    Using methods of the Mossbauer spectroscopy, scanning electron microscopy, and thermodynamic analysis of phase formation in silicate multi-component melts, the detailed study of composition, morphology, and properties of fly ash microspheres resulting from combustion of three coals (Irsha-Borodinskii, Kuznetskii and Ekibastuzskii) was carried out. About 60 microspherical products with an iron ...

  • 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 ...

  • 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 ...

  • Inquiry Into Coal Seam Gas

    Poorly planned or managed coal seam gas (CSG) exploration or extraction activities pose considerable risks to both groundwater and surface water systems. Key water quality issues, from my own perspective, are listed below. Specific issues may be of greater or lesser significance for particular projects, but all of these issues should be thoroughly and transparently assessed for all proposed ...

  • Planning the future of Botswana's coal

    Botswana has vast proven deposits of steam coal, which, for a long time, the government has wanted to develop but without much success. The main objectives of this study are: to forecast possible coal exports from Botswana and the land routes for these exports; to determine the competitiveness of Botswana's coal in world steam coal trade; to make recommendations on the appropriate policy for 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 ...

  • Low-emission coal burning technology

    Customer: Foster Wheeler Energy, Siemens, EnergoProjekt Katowice Challenge: One third of carbon dioxide emissions caused by humans come from the burning of fossil fuels in energy production. How to reduce them? Solution: Developing a circulating fluidised bed (CFB) boiler where fossil fuels are combusted with pure oxygen separated from the air. ...

  • 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. ...

  • Experience on coal reburn in a utility boiler

    Reburning is an in-furnace combustion modification technology for the reduction of NOx. By staging the introduction of the fuel, an environment is created where NOx generated by the combustion of the main fuel supply is subsequently consumed by the hydrocarbon radicals arising from the reburn fuel under reducing conditions. ENEL has retrofitted unit No. 4 of Vado ...

  • Coal company valuation, production and reserves

    The primary determinants of the value of a coal company are its cash flows and earnings, which is dependent upon the quantity and quality of the coal it produces and coal selling prices; future production potential, which is described by its reserves; and its inventory of capital assets, mining equipment, infrastructure, and acreage. The purpose of this paper is to establish the relationship ...

  • Review of coal as a promising source of lithium

    Coals are a major source of pollution in certain parts of the world due to mining, coal combustion, and disposal of fly ash. The recovery of valuable rare metals from coals or coal–processing byproducts is a promising way to utilise these traditional resources economically, efficiently and in an environmentally friendly way. Lithium, a highly interesting metal, has been found dispersed and even ...

  • What is the future of King Coal in China?

    When it comes to coal consumption, no other nation comes close to China. The country reigns as the world’s largest coal user, burning almost half of the global total each year. About 70 percent of China’s total energy consumption and nearly 80 percent of its electricity production come ...

  • AMETEK Land - World Coal - Beat the Heat

    Between the time a piece of coal is dug out of the ground and is burned in a power plant boiler, it has been through many stages of transportation and storage. One of the advantages of coal as a fuel for power generation is the ability to store substantial quantities on site. This provides a strategic buffer of at least one month's fuel supply, which can be valuable if there is a short- or ...

  • Beyond Coal; Optimization for Oil & Gas Units

    While coal reigns supreme among fossil-fuels for electricity production in North America, there are also substantial numbers of natural gas and oil-fired generating units. On one hand high fuel prices relative to coal can make it more difficult to cost-effectively operate these units; on the other, pressure to increase the capacity factors of these units will likely intensify in order to reduce ...

  • AMETEK Land `World Coal` - Feeling The Heat

    Richard Gagg, Industry Manager - Metals, AMETEK Land, discusses infrared line scanning as a technique that can be applied to detect early stages of spontaneous heating and combustion for coal moving on a belt conveyor system. The ability of belt conveyor systems to move large quantities of materials continuously has made them invaluable in mines and storage areas, and at transportation ...

  • China may be ready to kick coal habit

    There are still doubts. The statistics might be proved wrong. But it looks as if China might be starting to wean itself off its coal consumption habit. China produces and consumes nearly as much coal as the rest of the world combined. Coal, the most polluting of all energy sources, has powered the growth of China’s flyaway economy. But as incomes have risen, so has pollution. The country is ...
