  • Flying high on fuel-efficiency

    Within an industry where little things count in terms of weight, distance and economy, KLM Royal Dutch Airlines has come a long way in maximizing its fuel- efficiency. KLM has almost turned fuel-saving into a culture: since 2003 an increasing part of its entire organisation has been involved in decreasing kerosene consumption. This in order to save both costs and climate, as burning up one kilo ...

  • Fuel Homogenization

    The structure of the financial expenses of automotive businesses and boiler plants is quite varied, though it still allows to identify the main expenditures. First of all, it is the fuel, which accounts for no less than 40% of all costs. Fuel homogenization devices are designed to increase the quality of combustion, thereby saving resources. Homogenized fuel features good performance, ...

  • Efficiency of a standard gas-turbine power generation cycle running on different fuels

    This paper presents a study of second-law efficiency in a standard Brayton combined cycle power generation, using several paraffinic fuels ranging from methane to heptane. The main objective of the study was to identify a trend with the number of carbon atoms in the compound. In this way, a qualitative criterion can be built to evaluate the properties of poor-quality gas turbine fuels containing ...

  • Burner Efficiency

    The Customer The Company is a world leader in combustion technology. They design and manufacture burners for residential, commercial and industrial applications. The Process After the burners have been manufactured they must be tested to meet the standards of BTS-2000. This standard specifies the methods procedures for determining the performance and ...

  • Energy efficiency indicators for public electricity production from fossil fuels

    Electricity production is responsible for 32% of total global fossil fuel use, accounting for 132 EJ, and 41%, or 10.9 Gt of energy-related CO2 emissions. Improving the efficiency of electricity production therefore offers economic benefits and a significant opportunity for reducing dependence on fossil fuels, which helps to combat climate change and improve energy security. A set of indicators ...

  • EPA, DOT propose GHG/fuel efficiency standards for trucks, buses

    The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Transportation (DOT) have jointed proposed a rule that would establish the first-ever greenhouse gas (GHG) emissions and fuel-efficiency standards for buses and heavy-duty trucks. In a joint release on October 25, the agencies said that the new standards will result in GHG emissions reductions amounting to 250 ...

  • Xp3 Fuel Efficiency and Maintenance Case Study by Pepsi Guatemala

    PEPSI Guatemala Fuel: Diesel Machine/Type: Truck/Motor Test: Fuel Efficiency and Maintenance OBJECTIVE Evaluation of Xp³ for Diesel’s effectiveness in transport units Nos. 950 y 945. Fuel consumption history, oil analysis, and injectors were checked before Xp³ was added. Oil analyses were conducted after 5,352 km, with and without Xp³. In addition, a detail record of ...

  • New Fuel Efficiency Standards for Heavy-Duty Vehicles Are a “Win-Win-Win”

    America’s vehicles are on the road to becoming cleaner. Last week, President Obama directed his administration to set new fuel efficiency and greenhouse gas (GHG) emissions standards for medium- and ...

  • Improving Fuel Efficiency - Fred Weber, Inc. Realizes Significant Fuel Savings Using Combustion Catalyst Systems

    To see and hear the two Caterpillar 988Fs loading the crusher at Fred Weber's North Stone Quarry in Maryland Heights, Mo., one might think they are just like any other large wheel loaders working on any other quarry or construction job site in the Midwest. They look, sound and run like any well-maintained 988Fs would as they move quickly between the piles and the plant, but these are different; ...

  • Embedding nuclear physics rules and fuel chemistry limits in control algorithms for a fuel-efficient nuclear reactor

    In a nuclear reactor, the energy which is stored in the fuel is proportional to the amount of fissile material. The consumption of that amount, after a set burn-up, should and must result in delivering a set energy, barring leakages (losses). The loss of energy due to an inefficient control algorithm, after a set burn-up, is a problem that no one has yet addressed. Nuclear fuel chemists and ...

  • CHP efficiency for biogas

    Combined heat and power plant efficiency is a function of the conversion efficiency of the energy in the fuel gas to useful energy in the form of electricity and heat. A combined heat and power (CHP) plant is typically a reciprocating gas engine that uses the energy in the gas to drive a crank shaft. The crank shaft turns an alternator to ...

  • What’s undermining energy efficiency?

    Exhilaration swept through the energy efficiency industry as city after city, state after state and nation after nation set aggressive energy saving goals over the last several years. But with target dates nearing in certain jurisdictions, a more sober attitude now  permeates. Some governmentsare asking: Are we ...

  • Fuel alternatives for heavy equipment

    High fuel prices are leading composters and wood grinders to reevaluate diesel-guzzling heavy equipment, looking to alternatives that are both more cost-efficient and environmentally friendly. This could be as “simple” as filling up existing machines with biodiesel blends, could involve swapping out a diesel model for an electric one, or even go as far as generating electricity on site to power ...

  • Combined fuel cell?gas turbine plant for highly efficient power generation from renewable energy sources

    The impact of renewable energy sources on today's energy supply substantiates the importance of hydrogen as an energy carrier. Hydrogen can be directly produced from solar energy and is considered a promising technology for temporary storage of electrical energy from wind turbines and photovoltaic systems. The generation of electrical energy from stored hydrogen requires highly efficient systems ...

  • Energy efficiency without trying (and with)

    John Lennon wrote that life is what happens to you while you’re busy making other plans.  Apparently, the same is true of energy efficiency. Energy savings happen when we’re busy doing other things – Internet-based things specifically. We use email, bank online and download music not to save energy, but to make life easier and more interesting.  Energy efficiency is a ...

  • 5 out of 7 EU Carmakers on Track to Hit EU 2021 Fuel Efficiency Targets – Report

    Five out of seven European carmakers are on track to meet their CO2 targets by the 2021 deadline if they keep progressing as they have since the introduction of the law in 2008, T&E’s 2014 cars and CO2 report reveals. The report, in its 9th edition, ...

  • Effect of reforming on the overall efficiency of a solid oxide fuel-cell based power plant system fed by methane

    In the present work, energy and exergy system analysis are used to estimate the thermodynamic performance of a SOFC system fuelled by methane. More precisely, the present work examines in detail the influence of the presence or absence of the reformer within the whole apparatus and the consequent energy and exergy losses due to the reforming process. It was found that the exergetic efficiency for ...
