  1. 16. Elproduktion med ORC-teknik ombord på fartygsserien MK II.

    Kandidat-uppsats, Sjöfartshögskolan, SJÖ

    Författare :Per Lundgren; Håkan Mohlin; [2012]
    Nyckelord :ORC; spillvärme; energioptimering; Powerbox; MK II;

    Sammanfattning : Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. LÄS MER

  3. 17. TRACE Analysis of LOCA Transients Performed on FIX-II Facility

    Master-uppsats, KTH/Kärnkraftssäkerhet

    Författare :XIAO HU; [2012]
    Nyckelord :LOCA; TRACE; thermal-hydraulics transient; sensitivity analysis;

    Sammanfattning : As a latest developed computational code, TRACE is expected to be useful and effective for analyzing the thermal-hydraulic behaviors in design, licensing and safety analysis of nuclear power plant. However, its validity and correctness have to be verified and qualified before its application into industry. LÄS MER

  4. 18. Expansionsmaskiner istället för strypventiler - en effektivisering

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för fysik och astronomi

    Författare :Martin Nilsson; [2011]
    Nyckelord :exergy; pressure reducing valves; steam throttle; turbines; helical screw expander; one-step turbine; absorption heat pump; electricity production; electric power; exergi; strypventiler; turbin; turbiner; skruvexpander; absorptionsmaskin; elproduktion; elkraft;

    Sammanfattning : In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves. LÄS MER

  5. 19. Evaluation of a hygroscopic condenser

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Hampus Bellander; [2011]
    Nyckelord :Hygroscopic; condenser; waste heat; heating; absorption; heat pump; pilot plant;

    Sammanfattning : In Sweden the industries releases about 50 TWh / year of low temperature waste heat[1], often in the form of humid air flows. Today, conventional flue gas condensation is only exploiting a minor part of the energy from these flows. LÄS MER

  7. 20. Termisk Vattenpump

    Kandidat-uppsats, JTH, Maskinteknik

    Författare :Hans Klingberg; Marcus Stendal; [2009]
    Nyckelord :Thermal waterpump; Developing contries; Solar energy; Steam pump; Solar waterpump; Savery;

    Sammanfattning :   This degree project aims at developing a concept for how to use solar energy to pump up water. The target audience is people living in areas where the functioning of the electricity and water network is absent. In these areas, the hand-powered water pump is the most common technology. LÄS MER
