  • Danfoss VLT® 8000 improves reliability at power station

    Cockenzie, a 1200 MW coal-fired power station,  employs slurry pumps to convey the coal ash and fly ash. The hydraulic drive units and gearboxes  were a problem due to high maintenance cost. The easiest answer, frequency converter driven motor, directly coupled to the slurry pump. The system runs for up to 16 hours per day, also with a 38% reduction in energy ...

  • 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 ...

  • Methylmercury in mosquitoes around a large coal‐fired power plant in Central Ohio

    Emissions from coal‐fired power plants are the major anthropogenic source of mercury (Hg) in the environment. Because emitted Hg can be deposited near the source, concerns arise about the effects of coal‐burning facilities on levels of toxic methylmercury (MeHg) in biota near such sources. We investigated the potential impact of a large Hg‐emitting (450 kg in 2005) coal‐fired power station in ...

  • Technical and economic studies on the optimisation of prospective coal-fired power stations

    The paper considers problems of choosing rational parameters of thermal power plants on fossil fuel. A technique for comparison of the energy and economic efficiency of prospective coal-fired power plants is described. The optimisation results of parameters of combined-cycle plants with coal gasification at low and high-temperature levels and steam turbine plants on supercritical steam parameters ...

  • Disposal of saline wastewater from electrical power plants

    Saline wastewater from a coal-fired Utah Power Plant has been applied in central Utah, USA, since 1987, to irrigate various agricultural crops. The primary goals of this research: to dispose of saline wastewater by maximising actual evapotranspiration (ETa) and to prevent contamination of surface and groundwater by eliminating runoff and throughout the years (1987-2005). Plots were established ...

  • `Sahara Power` needs pan-European grid operator

    A consortium of leading European – mostly German – companies plans to invest €400 billion in a megaproject to generate solar power in the Sahara desert. “Desertec”, as the project is called, could cover 15 percent of European electricity demand. The problem is, how do you transport this power to Paris and Berlin? ‘It will not work without a pan-European grid operator.’ The figures for the ...

  • Over 170 Non-State Actors Have 80-100% Climate Commitments

    A report by CDP and The Climate Group reveals that over 170 major companies, states, regions, and cities around the world have committed to reducing their greenhouse gas (GHG) emissions by 80-100%, or procuring 100% of their power from renewable sources. ...

  • CSP industry gears up ‘to take advantage’ of new opportunities

    The recent announcement of the Environmental Protection Agency’s proposed new carbon emission standard for future coal-fired power stations has given the CSP industry yet another huge boost in the fight for an established place in the US energy market, through the use of hybrid CSP plants. This is just one example of the new opportunities this innovative industry is able to take advantage ...

  • MECONTROL UBC Systems for Power Station Moorburg - Case Study

    Efficient City Power Plant Hamburg/ Germany, One of the largest new coal fired power projects is the new power station Moorburg with a net capacity of 1640 MW and with a heating capacity of up to 650 MW. The close vicinity to the city Hamburg makes it possible to increase the efficiency of the units by up to 46.5% with electricity only and 61% with heating. With SH and RH temperatures of ...

  • Renewables expert hits out at electricity supply subsidies for fossil generators

    One of the UK’s leading renewable energy specialists has accused the Government of “gross hypocrisy” over the electricity supply auctions that began this week - less than seven days after the UK signed up to the landmark Lima Accord designed to cut carbon emissions. The controversial auction - which will see up to £1.8 billion in subsidies given to obsolete ...

  • In Perspective: Launching a third industrial revolution

    A third industrial revolution based on new communication and energy technologies needs strong political commitments, argues David Dickson. Just before Christmas, China's official Xinhua News Agency published an article extolling the virtues of the country's incoming premier, Li Keqiang, and describing his enthusiasm for ideas that the iconoclastic US commentator ...

  • The Clean Energy Voyage

    The United Nations Climate Convention meeting in Warsaw, Poland, comes with less than two years to go for governments to deliver on their promise of a universal new agreement by 2015 - this is the time for ambition rather than caution to define the international climate negotiations. We have in some ways been here before: the Copenhagen UN climate conference was also scheduled to deliver a ...

  • UK energy – time to face some hard truths

    How can the UK meet its future energy needs? Tom Delay, CEO of the Carbon Trust, looks at how we can solve the problem with our energy future. The future of nuclear power in the UK looks well and truly stuck. The whole episode illustrates how high the stakes are at present for our energy future. Last month the new nuclear plant at Hinckley C was granted planning permission but we ...

  • Cenospheres - Case Study

    The problem: A cenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina and filled with air or inert gas, typically produced as a byproduct of coal combustion at thermal power plants. On average 0.5% of the fly ash generated in a coal fired power station boiler are Cenospheres. When fly ash is wet discharged in to ash ponds/lagoons cenospheres float on ...

  • Why European policymakers shouldn’t be concerned about security of gas supply

    Gastech News: What are the key issues affecting gas companies today? Mark Simons: The biggest issue affecting gas companies within the European gas industry is low prices, because low prices mean less revenue and less profit. To add to that, in Europe, the competition for gas from coal and renewables means that demand is down and that’s ...

  • Fears over future power shortages highlights requirement for standby power

    Britain is facing a future where energy prices will escalate and energy sources become insecure and unreliable according to a recent report from the industry regulator Ofgem.  It stated that a combination of a global financial crisis, tough environmental targets, increasing gas import dependency and the closure of ageing power stations are to blame for rising costs and uncertain ...
