  • 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 ...

  • The role of coal technologies to support responsible economic growth

    The Asian Pacific region is home to the fastest-growing economies in the world. These economies are expected to double gross domestic product (GDP) in the next decade, and coal will play a major role as the primary energy source for electric power. The tremendous projected financial burden associated with the installation of new, coal-fired electric power facilities to fuel this unprecedented ...

  • Coal market outlook in China

    Coal is the major primary energy source in China. It is forecast that coal will account for over 60% of the primary energy consumption mix, and the total coal demand will reach 2.3-2.9 billion tons in 2020. However, ensuring the coal supply will be faced with a lot of obstacles in fields such as the degree of detailed exploration of coal reserves, the level of mining technology and mine safety, ...

  • 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 ...

  • Laboratory scale tests of coal-based hydrogen production with CO2 capture in the aspect of clean coal technologies

    In the light of continuously increasing oil prices as well as stronger environmental regulations, an important issue becomes finding an alternative to fossil fuels. Scientists agree that hydrogen seems to be an ideal, price-competitive and environment-friendly future energy carrier. One of the most effective methods of hydrogen production is the process of steam gasification of coal to ...

  • Low-volatile coal combustion technologies in Vietnam: issues and strategies

    Vietnam has planned to install a number of coal-fired power plants with unit's capacity of up to 600 MW. Present experience shows that available low volatile anthracite coal is difficult to burn in the PC fired boilers. In this paper, the CFB combustion technology is proposed based on the experiences of coal-fired power plants around the world used similar coal characteristics. Later, a ...

  • Present status and future prospect of clean coal technology in China

    Coal consumption accounts for about two thirds of the primary energy consumption in China. High economic growth has brought about a rapid increase of coal consumption. Low-efficiency combustion of a large amount of coal caused coal-smoke related air pollution. The Chinese government put forward plans to develop clean coal technology in the early 1990s, and has listed it as one of the emphases for ...

  • Remediation of Abandoned Coal Mines Using Coal Combustion Products

    A slurry of mine water and coal combustion fluidized bed ash (FBA) was injected into an abandoned coal mine in Eastern Oklahoma in July 1997. Oil-field technology was used to inject 1.8 Gg (418 tons) of FBA through five wells in 15 hours. Alkaline minerals in the FBA neutralized acidity and imparted alkalinity to the mine water. Thus, this remediation method uses the waste from an industrial ...


  • Tabas coal preparation plant wastewater treatment with membrane technology

    The goal of the present work is the Tabas coal preparation plant wastewater treatment using membrane technology. Polyacrylonitrile membrane was prepared through phase inversion method and then developed by annealing process. Also, high fouling resistance membranes were prepared by the embedding of TiO2 nanoparticles using self-assembling and blending methods. The effect of immersion time and ...

  • 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. ...

  • 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 ...

  • 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 ...
