  1. 1. Thermodynamic properties of humid air and their application in advanced power generation cycles

    Författare :Xiaoyan Ji; Jinyue Yan; Umberto Desideri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air-water mixture; humid air; properties; wet cycles; dry air; water; enthalpy; entropy; heat capacity; density; evaporative gas turbine; compressed air energy storage; Chemical engineering; Kemiteknik;

    Sammanfattning : Water or steam is added into the working fluid (often air) in gas turbines to improve the performance of gas turbine cycles. A typical application is the humidified gas turbine that has the potential to give high efficiencies, high specific power output, low emissions and low specific investment. LÄS MER

  3. 2. Humidification Processes in Gas Turbine Cycles

    Författare :Marcus Thern; Kraftverksteknik; []
    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

  4. 3. Evaluation, Experience and Potential of Gas Turbine Based Cycles with Humidification

    Författare :Torbjörn Lindquist; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Validation; Recuperator; Flue Gas Condensation; Humidification; Gas Turbine; Advanced Thermodynamic Cycles; HAT; Humid Air Turbine; Evaporative Gas Turbine Cycle; EvGT; Operating Experience; EvGT Pilot Plant; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Sammanfattning : Gas turbines, in simple and combined cycle, are common and economically profitable on the power generating market today. Several new cycles have been proposed as future competing technologies, but all studies about these cycles have, so far, been paperwork. LÄS MER

  5. 4. 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

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

    Författare :Björn Fredriksson Möller; Kraftverksteknik; []
    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
