  3. 2. Solfångare : Konstruktion och utvärdering av prestanda

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Jenny Lindström; [2016]
    Nyckelord :;

    Sammanfattning : Energy supply and impact on the environment are two main problems that the world faces right now. During a longer period of time fossil fuels has been used as primary energy source. The use of fossil fuels has contributed to large emissions of greenhouse gases and global warming. LÄS MER

  4. 3. Volumetric Solar Receiver for a Parabolic Dish and Micro-Gas Turbine system : Design, modelling and validation using Multi-Objective Optimization

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Roberta Mancini; [2015]
    Nyckelord :volumetric receiver; parabolic dish; OMSoP; micro-gas turbine; multi-objective optimization; ray tracing;

    Sammanfattning : Concentrated Solar Power (CSP) constitutes one suitable solution for exploiting solar resources for power generation. In this context, parabolic dish systems concentrate the solar radiation onto a point focusing receiver for small-scale power production. LÄS MER

  5. 4. Techno-economic Appraisal of Concentrating Solar Power Systems (CSP)

    Magister-uppsats, Energi och miljöteknik

    Författare :Maria Gasti; [2013]
    Nyckelord :;

    Sammanfattning : The diffusion of Concentrating Solar Power Systems (CSP) systems is currently taking place at a much slower pace than photovoltaic (PV) power systems. This is mainly because of the higher present cost of the solar thermal power plants, but also for the time that is needed in order to build them. LÄS MER
