  • Better combustion airflow monitoring at the Hunan Yiyang power plant

    China has experienced tremendous growth in electricity demand over the past two decades. Coal-fired plant construction has exploded in the country to meet its seemingly insatiable appetite for electricity. Because most power plants in China use coal as fuel, it is imperative that new coal-fired plants be as clean and efficient as possible. This demand for cleaner plants has led to new and ...

  • Advances in flashpoint testing: economic impact

    Flashpoint testing is one of the oldest methods of the ASTM D02 Committee on Petroleum Products and Lubricants, which was formed in 1904. The most prevalent standards are ASTM D56 (Tag Method), D92 (Cleveland Method), and D93 (Pensky-Martens Method). These classical techniques, commonly referred to as open-cup and closedcup methods, share a common principle: A test flame is lowered into the ...

  • Evaluating advanced automotive energy technologies: a multivariate mobility contribution metric

    Mobility technology is beginning to shift from gasoline-fuelled, internal combustion engines to a variety of alternate fuels and powertrains, including hybrid and fuel cell vehicles. The benefits and/or limitations of many of these technologies are not well characterised by a simple fuel economy metric: mobility is a complex system requiring a multivariate systems measure, especially ...

  • Advanced Application of Product Gases of Thermal Conversion of Biomass and Waste; Integration With the Fischer-Tropsch Synthesis

    The Netherlands Energy Research Foundation (ECN) is studying the advanced application of product gases from the thermal conversion of biomass and waste (B&W). The Fischer-Tropsch (FT) synthesis is the most promising as it affords diesel-like fuels of high quality and free from sulfur and aromatics. A slurry bubble FT reactor with an iron catalyst is the most suitable for B&W syngases. To optimize ...

  • Effect of injection timings on the performance, emission and combustion characteristics of DI diesel engine running on Calophyllum inophyllum linn oil (honne oil)

    The present work examines the use of a non–edible vegetable oil namely honne oil, a new possible alternative fuel for diesel engine. A direct injection (DI) diesel engine typically used in agricultural sector was operated on neat diesel (ND) and neat honne oil (H100). Static injection timing (start of static injection timing) was changed to study the performance, emission and combustion ...

  • Evaluating Risks to Wildlife from Coal Fly Ash Incorporating Recent Advances in Metals Risk Assessment

    Current scientific advances in metal/metalloid risk assessment were applied to evaluate risk to aquatic and riparian wildlife species potentially impacted by residual coal fly ash after clean‐up of an unprecedented large ash release into an aquatic environment, the first assessment of its kind. Risk was evaluated using multiple lines of evidence (LOE) including (1) tissue‐based risk assessment ...

  • The isoengine: realisation of a high-efficiency power cycle based on isothermal compression

    A novel high-efficiency internal combustion engine for power generation and direct-drive applications is being developed. Distillate-fuelled power plants in units of 7 MW electrical output are predicted to reach a net electrical efficiency of 60%. An efficiency of 58% is targeted for the gas-fired version. This compares with a net electrical efficiency of about 45% for advanced reciprocating ...

  • Improve Boiler Efficiency

    In many chemical plants, the electricity the plant uses is derived from a natural gas power plant or a co-generation plant burning waste gas streams. In large boilers (Figure 1), power plants bring together air and fuel (natural gas, waste gas, oil or coal) for combustion, which creates heat. The heat boils the water, creating steam. The steam runs through a turbine, which causes the turbine to ...

  • 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 ...
