  2. 16. Modelling of Biomass Syngas Combustion with CFD

    Author : Nikolaos Papafilippou; Rikard Gebart; Kentaro Umeki; Muhammad Aqib Chishty; Gunnar Hellström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Syngas; LES; FGM; Combustion; Energiteknik; Energy Engineering;

    Abstract : Gas turbines integrated with biomass gasification in a combined cycle power plant (Bio-IGCC) provide a path to power production with very high efficiency. Over 60% fuel-to-power efficiency has been demonstrated with natural gas. READ MORE

  4. 17. Homogeneous Lean Combustion in Downsized Spark-Ignited Engines

    Author : Kristoffer Clasén; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; lean combustion; emissons; transportation;

    Abstract : Emissions of greenhouse-gasses and noxious compounds from internal combustion engines propelling personal transportation vehicles is an imminent issue in the society. Therefore, it is vital to find means of reducing these emissions to decrease the impacts of transportation. READ MORE

  5. 18. Oxy-Fuel Combustion - The Control of Nitrogen Oxides

    Author : Fredrik Normann; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxy-fuel; NOx; O2 CO2; combustion; emission; nitrogen oxides;

    Abstract : Oxy-fuel combustion is one of the main candidates for carbon dioxide capture from power plants. In oxy-fuel combustion, oxygen diluted with recycled flue gas oxidizes the fuel. The elimination of air-borne nitrogen generates a flue gas that mainly consists of carbon dioxide and water. READ MORE

  6. 19. Turbocharged HCCI Engine, Improving Efficiency and Operating Range

    Author : Thomas Johansson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HCCI; NVO; turbo; direct injection; combustion; CAI; low temperature; simulation; engine;

    Abstract : Increasing fuel prices and environmental concern drives the research and development for the internal combustion engine. Homogeneous Charge Compression Ignition (HCCI) is a promising combustion concept with high fuel efficiency and low emissions. READ MORE

  7. 20. Advanced Laser-based Multi-scalar Imaging for Flame Structure Visualization towards a Deepened Understanding of Premixed Turbulent Combustion

    Author : Bo Zhou; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser Diagnostics; PLIF; High Spatial Resolution; Multi-scalar Instantaneous Visualization; HCO CH Radicals; Distributed Reaction Zone; Mild Combustion.; Combustion Regimes; Turbulence Flame Interaction; Turbulent Premixed Combustion; Fysicumarkivet A:2015:Zhou;

    Abstract : The work presented in the thesis concerns the developments of laser-based diagnostics and its application to the study of turbulent premixed combustion. The diagnostic developments, mainly concerned with planar laser-induced fluorescence (PLIF), are intended to provide instantaneous visualization of the key species originating from the combustion processes involved in the burning of hydrocarbons and nitrogen-containing fuels under turbulent conditions.
