  1. 1. 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.

  3. 2. 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. The Fate of Sulfur during Oxy-Fuel Combustion

    Författare :Daniel Fleig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pulverized coal combustion; oxy-coal; SO3; Oxy-fuel; SO2; sulfur;

    Sammanfattning : Oxy-fuel combustion, where air is replaced by O2 and recycled flue-gas to enrich combustion products, is one of the main CO2 capture technologies suitable for large-scale coal-fired power plants. The changed combustion conditions in oxy-fuel combustion influences the sulfur chemistry, which has recently been the subject of increased attention due to the importance of sulfur species in corrosion and flue-gas cleaning issues.

  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. Characterization of oxy-fuel flames - their composition, temperature and radiation

    Författare :Klas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion; O2 CO2; NO formation; Radiation; Oxy-fuel; Flame properties;

    Sammanfattning : Oxy-fuel combustion is receiving growing attention as one of the promising CO2 capture technologies in connection to power production. Yet, significant efforts are required in research and development of this combustion process in order to be able to design and optimize a full scale power plant. LÄS MER
