  2. 11. Conceptual Gas Turbine Modelling for Oxy-fuel Power Cycles

    Author : Egill Maron Thorbergsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Semi-closed Oxy-fuel Combustion Combined Cycle; Graz cycle; Carbon capture and storage; oxy-fuel combustion combined cycles; conceptual compressor design;

    Abstract : The electricity consumption in the world is growing at an ever increasing rate. Today's electricity generation is highly dependent on combustion of fossil fuel. This leads to emissions of carbon dioxide into the atmosphere. Increased atmospheric CO2 concentration results in higher average surface temperature and climate change. READ MORE

  4. 12. Combustion, Fluid Dynamics and Heat Transfer in Oxy-fuel and Air-Fired CFB boilers

    Author : Sadegh Seddighi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon Capture and Storage; Combustion; Circulating Fluidized Bed; Oxy-Fuel; Multi-Phase Reacting Flow; Boiler Design; Emission; Fluid Dynamics; Heat Transfer;

    Abstract : The studies described in this thesis develop and encode modeling tools for the design and scale-up of oxy-fuel circulating fluidized bed (CFB) boilers across a wide range of operational conditions. The modeling comprises fluid dynamics, combustion, and heat transfer and uses expressions that are proposed in this work or derived from the literature, together with experimental data obtained under both oxy-fuel-fired and air-fired conditions.

  5. 13. Combustion of selected alternative liquid fuels at oxy-fuel conditions: experiments and modelling

    Author : Jenny D. Nauclér; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alcohols; Nitromethane; Chemistry; Laminar burning velocity; Ignition; Combustion; Fysicumarkivet A:2016:Nauclér;

    Abstract : Combustion of fuels is a major source of energy and at the same time a threat to the environment. Carbon dioxide (CO2) emissions are one of the obstacles on the route to cleaner energy. Combining Carbon Capture and Storage-technology (CCS) with use of biofuels lead to a negative net release of CO2 can be achieved. READ MORE

  6. 14. The Oxy-Fuel Process - Towards high efficient operation

    Author : Fredrik Normann; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oxy-fuel O2 CO2 Combustion NOx Thermal-NO Co-production;

    Abstract : The power generation system is facing large changes to meet the demands on reduced emissions of carbon dioxide (CO2). Oxy-fuel combustion with capture of CO2 is a promising option to meet those demands. READ MORE

  7. 15. High-Temperature Corrosion Chemistry in Oxy-Fuel Combustion

    Author : Thomas Ekvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Drastic cuts in global CO2 emissions are needed to mitigate the global warming if limiting global warming to 2ºC. The power generation sector is largely based on fossil fuels and produces a significant share of the global CO2 emissions. READ MORE
