  • Combustion of advanced non-toxic hybrid propellants

    Combustion characteristics and fuel regression behaviour have been studied for two fuels utilising 98% rocket-grade hydrogen peroxide (RGHP) as oxidiser. Two test series (A and C) involved a total of 13 firings of dicyclopentadiene (DCPD) fuel grains and series B involved nine firings of DCPD grains loaded with various amounts of lithium aluminium hydride, LiAlH4 (LAH). A laboratory-scale ...

  • Pragmatic Efficiency Limits for Internal Combustion Engines

    This article gives an overview of the thermodynamic principles demonstrating that the maximum efficiency theoretically possible with a hydrocarbon fueled internal combustion engine is one hundred percent. From this basis the focus turns to articulating irreversibilities that naturally occur within the processes of converting the chemical energy in the fuel into shaft work. These losses are ...

  • Performance and emission characteristics of a DI compression ignition engine operated on PODL biofuel

    This paper presents the results of investigations carried out both numerically with the CFD code CONVERGE and experimentally on a single-cylinder, four stroke, direct-injection, CI engine. The tests are performed with neat diesel, neat palm oil (PO) and different blends of PO and the D-limonen solvent (PODL), like 10%, 15% and 20% by mass of D-limonen in PO (PODL10, PODL15 and PODL20). Engine ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The Boiler Optimization Journey

    The Boiler Optimization Journey talks about the evolution of power plant optimization software over the past 15 years, from neural network-based systems that advised operators how to bias fuel and air in the furnace to reduce NOx emissions, to integrated closed-loop combustion and sootblowing systems that use hybrid AI technologies, solve a broad range of challenges, and provide enhanced ...

  • 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 ...

  • Is `Dark Fuel` the same as `Bad Fuel` and can I still use it?

    Algae-X FAQ’sIs 'Dark Fuel' the same as 'Bad Fuel' and can I still use it?This is a question many of us have asked more than once. And what we really want to know is: 'Will the stuff damage my engines?' Engines are expensive, ruining an engine is costly and operating an engine on 'bad fuel' is not wise. We all know that most engine failures start in the fuel tank. When all mechanical parts ...

  • 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 ...

  • 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 ...
