  1. 1. Advanced Gas Turbine Cycles with Water-Air Mixtures as Working Fluid

    Författare :Niklas Ågren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas turbine cycles; HAT cycles; evaporative cycles; power generation;

    Sammanfattning : Since the early 80's, the worldwide utilization of gas turbines for thermal power generation has increased rapidly. They have less pollution than any other major combustion energy converters. LÄS MER

  3. 2. 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

  4. 3. Humidification in Evaporative Power Cycles

    Författare :Farnosh Dalili; KTH; []
    Nyckelord :Gas Turbines; EvGT; HAT; Humidification; Evaporator; Saturator;

    Sammanfattning : Evaporative gas turbine cycles (EvGT) show an exceptionalexhaust heat recovery potential, which makes them a strongcompetitor to other advanced gas turbine cycles, especiallyfrom small to intermediate sizes. Evaporative gas turbines aredistinguished by humidifying the working fluid beforecombustion at temperatures below the boiling point of water;and the heat required for evaporation of water is partly takenout of the exhaust gas.

  5. 4. 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

  7. 5. 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
