  1. 1. Oxy-Fuel Combustion - The Control of Nitrogen Oxides

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

    Sammanfattning : 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. LÄS MER

  4. 3. Extraction of logging residues for bioenergy : effects of operational methods on fuel quality and biomass losses in the forest

    Författare :Bengt Nilsson; Johan Bergh; Gudmund Vollbrecht; Rolf Björheden; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest fuel; Storage; Fraction composition; Needles; Defoliation; Moisture content; Nutrients; Nitrogen; Norway spruce; Picea abies; Skogsbränsle; Lagring; Fraktionsfördelning; Barr; Avbarrning; Fukthalt; Näringsämnen; Kväve; Gran; Picea abies; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Wood products play a key role in the transformation to a more sustainable society based on renewable bio-based resources, together with the positive effects on climate mitigation by replacing fossil fuels. However, to increase the use of forest fuel in practice it is important to understand the effects of handling and storage on its quality and removal of nutrients from the forest. LÄS MER

  5. 4. Combustion and Nitrogen Chemistry in Oxy-Fuel Flames

    Författare :Daniel Kuehnemuth; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nitric oxide; Gasification; Oxy-fuel; Reburning;

    Sammanfattning : Oxy-fuel combustion is a Carbon Capture and Storage (CCS) technology that recently has shown afast progress towards the industrial scale application. In oxy-fuel combustion, oxygen instead of air isused as oxidizer to burn the fuel. The oxygen is mixed with recycled flue-gas in order to control theoverall combustion and heat transfer conditions.

  7. 5. Conceptual Thermodynamic Cycle and Aerodynamic Gas Turbine Design - on an Oxy-fuel Combined Cycle

    Författare :ADRIAN NILSSON DAHLQVIST; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; combined cycle; conceptual design; aerodynamic; mid-span design; through-flow design; oxy-fuel; SCOC-CC; OCC; gas turbine; Combined cycle; conceptual design; aerodynamic; mid-span design; Through-flow design; Oxy-fuel; SCOC-CC; OCC;

    Sammanfattning : The world is today facing a serious problem with global warming, which is heading towards an appallingly high temperature level. The greater part of the overall climate science community agree that global warming is caused by the greenhouse effect, which depends largely on emitted CO2 emissions from the combustion of fossil fuel.
