  1. 6. A Thermoeconomic Evaluation of CO2 Capture with Focus on Gas Turbine-Based Power Plants

    Detta är en avhandling från Department of Energy Sciences, Lund University

    Författare :Björn Fredriksson Möller; Lund University.; Lunds universitet.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; climate change; optimisation; genetic algorithms; applied thermodynamics; Thermal engineering; AZEP; GTPOM; gas turbine; CO2 capture; thermoeconomy; termodynamik;

    Sammanfattning : The increasing emissions of carbon dioxide from fossil fuel burning are today thought to be one of the main contributors to global warming. At the same time, developing countries are striving for an increased welfare and burning more fossil fuel, which in turn is augmenting the greenhouse gas effect. LÄS MER

  2. 7. Modelling and Numerical Analysis of the Centrifugal Compressor and its Operation in the Pressurised SOFC GT Process

    Detta är en avhandling från Thermal Power Engineering

    Författare :Andre Hildebrandt; Lund University.; Lunds universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; radial compressor; Gas Turbine; Termisk teknik; Solid Oxide Fuel Cell; termodynamik;

    Sammanfattning : Small-scale power plants based on the SOFC-GT (Solid Oxide Fuel Cell-Gas Turbine) system are foreseen for future application such as APU units in flight transportation systems or stationary power production. Although these new systems offer high load flexibility and potentially high efficiency, there are several constraints referring to thermal/mechanical stress of the fuel cell as well as to a potential risk of aerodynamic instability of the GT compressor due to the different physical behavior of the SOFC and the GT.

  3. 8. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

    Detta är en avhandling från Division of Building Materials, LTH, Lund University

    Författare :Jonathan Karlsson; Lund University.; Lunds universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

    Sammanfattning : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

    Sammanfattning : Modern societies' functionality is strongly dependent on the electricity. Efficient, environment friendly, and economical power production has been in focus for a long time. LÄS MER

  5. 10. Humidification Processes in Gas Turbine Cycles

    Detta är en avhandling från Division of Thermal Power Engineering Department of Energy Sciences Faculty of Engineering Lund University

    Författare :Marcus Thern; Lund University.; Lunds universitet.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; HAT; Biomass; Biofuel; Humidification; Evaporation; Evaporative gas turbine ; Humid air turbine ; Termisk teknik; termodynamik;

    Sammanfattning : The global climate change caused by emissions of greenhouse gases from combustion processes has been recognized as a continuously growing problem and much research focuses on improving the environmental performance of gas turbines. The potential of improving gas turbine component efficiencies has become smaller each decade and therefore, thermodynamic cycles have become more interesting for power producing units. LÄS MER
