  • Optimal maximum continuous operating load of fuel fired steam–based generating units

    This paper establishes the optimal maximum continuous operating load of fuel fired steam based thermal units without endangering the operation, asset life or carbon footprint. The interconnectivity between unit loadability and energy efficiency (represented by heat rate) enables the unit to be loaded to as high as 10% over and above the 100% maximum continuous rating (MCR) provided the energy ...

  • The international coal industry: comments on the paper by David Humphreys and Keith Welham

    This comment discusses in more detail one of the primary messages in the paper by David Humphreys and Keith Welham, namely the fundamental shift in the steam coal industry away from security of supply concerns and national focuses towards an international and cost-driven perspective. On the supply side, this has meant an increased focus on mining productivity. By consulting recent research, this ...

  • Unconventional Crude Upgrading Challenges

    Crude markets are being influenced by increasing prices, stagnate discovery rates, increased world demand, and competition from alternate sources such as bio-fuels, coal and unconventional crude. Future crude supplies from conventional sources are anticipated to be, in part, incrementally replaced by production of unconventional crude from Western Canada and Venezuela, in addition to other ...

  • 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 ...

  • Renewable energy in Armenia

    Armenia does not have any fossil fuel or coal reserves; therefore, it is entirely dependent on the imported fuel for transportation, electricity generation, and heat production. Armenian Government has plans to develop renewable energy resources. Renewable energy may not be the major source of energy development in Armenia but it should be an important component of it. A renewable energy road ...

  • Cumulative exergy consumption (CExC) analysis of energy carriers in China

    Cumulative exergy consumption (CExC), which represents the total exergy of natural resources required to provide a product, is an appropriate indicator for quantifying the depletion of natural resource. The objective of this study is to determine the CExC values of the principal energy carriers in China, which is the largest energy producer in the world, through the matrix method (balance ...

  • The influence of climate change considerations on energy policy: the case of Russia

    To those working on climate change, it is obvious that energy policy should be influenced by climate change considerations. The question that this paper seeks to answer is, to what extent do they influence policy and what contribution can a careful analysis of the costs and benefits of climate change options have on the formulation of that policy? We seek to understand this by looking in some ...

  • Sources and technology for hydrogen production: a review

    A comprehensive review of various processes and possible sources of hydrogen production are discussed in this paper. The various process for hydrogen production reviewed includes industrial process i.e. steam reforming, thermal cracking, partial oxidation of fossil fuels, coal gasification, electrolysis, thermochemical etc. and new emerging processes like photolysis, photo-voltaic electrolysis, ...

  • 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 ...

  • Combustible Briquettes for All Your Camping Requirements

    Coal has been in use since historical times both to cook food and to produce energy. Coal briquettes are a great fuel source and are manufactured in specialized briquetting plants that offer different varieties of combustible briquettes. What Exactly Is A Briquette? Briquettes are an amazing source of combustible energy that ...

  • 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 ...

  • Water impounded bottom ash collection systems

    Ash is a by-product of the combustion process in power generating stations that burn coal as a primary fuel. Combustion takes place in a boiler that is actually a large open furnace. The walls of the furnace are lined with pipes that carry water to produce steam that powers a turbine generator. Ash is present in two forms: 1) Fly-ash, a lighter material that exits the boiler in the flue-gas ...

  • Life cycle analysis of world electricity in the 21st century using the world energy LCA model

    World energy and electricity demand by the year 2100 has been analysed using the World Energy LCA (Life Cycle Analysis) Model. Three energy scenarios are set-up: the current fossil fuel-intensive pattern, as well as renewable-intensive and nuclear-intensive alternatives. The performance of CO2 emissions, resource availability, total investment costs, indirect energy consumption from the life ...

  • A roadmap for a secure, low-carbon energy economy

    This “roadmap” presents the results of a year-long effort by the Center for Strategic and International Studies (CSIS) and WRI to identify a set of policies to address energy security and climate change simultaneously. At first glance, improving energy security and addressing climate change may seem irreconcilable goals: achieve an adequate, reliable, and affordable energy supply for the United ...

  • Performance of externally fired combined cycle (EFCC)

    The externally fired combined cycle (EFCC) which utilises coal as the primary fuel through a gas turbine cycle is a clean coal technology. Natural gas is used as the supplementary fuel, but the ultimate goal of the EFCC concept is a coal only option. In this study, the performance of the EFCC plant is evaluated based on the first and the second laws of thermodynamics, considering various levels ...

  • Quantitative assessment of solar energy geo-policy risks

    Fossil fuels, such as coal, oil, gas, and wood, are the major part of contemporary energy mix. However, forecasts predict that solar energy will take up to 70% of global energy mix by year 2100. Solar energy has embedded risks, e.g., social, geopolitical, health-related, etc. These risks should be addressed in advance to prevent negative consequences but little research has addressed systemic ...

  • West Virginia repeals the alternative and renewable energy portfolio standard

    On February 3, 2015, West Virginia repealed the Alternative and Renewable Energy Portfolio Act that was originally passed and adopted in 2009. This Act (the Standard) required utilities serving 30,000 residential customers or more to generate at ...

  • 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 ...
