  • 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 ...

  • Coal and its future are fueling conflicts around the globe

    "Coal Wars: The Future of Energy and the Fate of the Planet" (Palgrave Macmillan), by Richard Martin Fierce conflicts over coal are taking place around the globe, but author Richard Martin says the decline and ultimate demise of the fuel that powered the Industrial Revolution is inevitable and cannot be reversed. What he cannot predict, he says, is whether the transition to energy sources that ...

  • 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 ...

  • Used Tires are Better Fuels than Coal and Coke, Aliapur Says

    A research conducted by French company Aliapur provides proof that burning used tires produce comparable energy (heat output) but less fossil CO2 emissions than burning coal or petroleum coke. Since used tires are not 100% fossil unlike coal and coke, their combustion emissions have renewable carbon or biomass fraction. Through ASTM D6866 testing, the biomass fraction of used tires was ...

  • How to create qualitative fuel from water and coal: case study

    What is “coal-water fuel”?   Coal-water fuel (CWSF or CWS or CWF) is a fuel which consists of fine dispersed coal particles, water and plasticizing agent. This type of fuel is widely used as an alternative to gas and black oil on different heat generating facilities. The operational economy is the main of advantages ...

  • Geology and coal potential of Somaliland

    Geological field mapping along with available geological and drilling data suggest that Somaliland (Northwestern Somalia) has favourable stratigraphy and structure for coal deposits. Lignitic to sub-bituminous coal deposits with ages from Jurassic to Oligocene-Miocene occur in various locations across the country including Hed-Hed valley south of Onkhor, Guveneh hills north of Las Dureh and Daban ...

  • 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 ...

  • 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 ...

  • Co-firing Solid Recovered Fuels (SRFs) with brown coal in large-scale pulverised fuel power plants – a simulation approach

    The results of the numerical simulations performed in a pulverised fuel boiler co-firing coal and Solid Recovered Fuels (SRFs) are presented. SRFs are initially modelled as a mixture of two different fractions (biogenic and plastic) and further simplifications are proposed to save computational expenses. The SRF submodels are validated with available data obtained from a laboratory-scale ...

  • 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. ...

  • 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 ...

  • The Great Transition – Closing Coal Plants

    We may wake up one morning in the not-too-distant future and realize that the world has reached a tipping point on coal. So concludes the Earth Policy Institute in Chapter 3 of its upcoming report entitled The Great Transition: Shifting from Fossil Fuels to Solar and Wind Energy. Use of this fuel will be declining worldwide, as ...

  • Production of synthetic gasoline and diesel fuels by alternative processes using natural gas, coal and biomass: process simulation and economic analysis

    The problem of producing synthetic liquid fuels by alternative routes is addressed. Industrial processes known as Gas To Liquid (GTL), Coal To Liquid (CTL) and Biomass To Liquid (BTL) are considered: they use natural gas, coal and biomass as feedstocks, respectively. By means of process simulation, it is shown that the fuel produced on a weight basis per unit of feedstock (natural gas, coal and ...

  • Coal and fuel burning effects on the atmosphere as mediated by the atmospheric electric field and galactic cosmic rays flux

    Emissions into the atmosphere of Greenhouse Gases (GHGs) and particulate matter resulting from fossil fuel burning are considered to be the main anthropogenic forcing on the global climate. We show here that the external cyclic influences of cosmic origin that modulate the earth's climate may either reinforce or mitigate the 'local' terrestrial forcings. Among the external influences is cosmic ...

  • Thermal behaviour study of senakin coal and Refuse Derived Fuel (RDF) blends during pyrolysis using thermogravimetric analysis

    Preliminary Thermogravimetric (TG) studies of pyrolysed Refuse Derived Fuel (RDF)–coal blends (20 to 80%) at various heating rates, 20, 40, 60 °C•min–1 have been performed to develop an efficient locally sourced renewable solid fuel. The characteristics of the coal/RDF blends followed those of the parent fuels in additive manner. Among the tested blends, 50:50 blends showed the optimum blend ...

  • 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 ...
