  1. 1. Celestial Cycles : Astronomical Concepts of Regeneration in the Ancient Egyptian Coffin Texts

    Författare :Patrik Wallin; Katja Goebs; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; Archaeology; Ancient Egypt; Coffin Texts; Astronomy; Middle Kingdom; calendars; time; Arkeologi; Archaeology subjects; Arkeologiämnen; Egyptology; Egyptologi; Informatics; computer and systems science;

    Sammanfattning : This study analyzes the astronomical references found in the ancient Egyptian Coffin Texts. Chapter i presents the aim and method of this study as well as describing the primary sources and previous research. Chapter 2 deals with the conceptual background for the three cycles, as related to the year, month and the day as units of time. LÄS MER

  2. 2. Biomass and Natural Gas Hybrid Combined Cycles

    Författare :Miroslav Petrov; KTH; []
    Nyckelord :biomass; naturalgas; hybrid; combined cycle; gas turbine; internal combustion engine; simulation; electrical efficiency; total efficiency;

    Sammanfattning : Biomass is one of the main natural resources in Sweden.Increased utilisation of biomass for energy purposes incombined heat and power (CHP) plants can help the country meetits nuclear phase-out commitment. LÄS MER

  3. 3. Oxy-Fuel Combustion Combined Cycles for Carbon Capture

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

    Sammanfattning : A short and medium term method to decrease carbon dioxide emissions is carbon capture and storage. This method captures carbon dioxide from point sources of emissions and then stores the carbon dioxide in geological formations. LÄS MER

  4. 4. Developing Humidified Gas Turbine Cycles

    Författare :Michael Bartlett; KTH; []
    Nyckelord :advanced gas turbine cycles; evaporative; humidified; power; heat and power;

    Sammanfattning : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. LÄS MER

  5. 5. Evaporative Cycles - in Theori and in Practise

    Författare :Per M Rosén; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; Trigeneration; Combustion Engines; Gas Turbines; CHAT; HAM; HAT; Evaporative Cycles; EvGT; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Sammanfattning : The thesis is based on applied research, rather closed to industrial development. The developed simulation model, for pre-design of evaporative gas turbine cycles, has been validated in a 600 kW pilot plant and in rebuilt turbo-charged diesel engines. LÄS MER
