1. 1. Conceptual Thermodynamic Cycle and Aerodynamic Gas Turbine Design - on an Oxy-fuel Combined Cycle

   Författare :ADRIAN NILSSON DAHLQVIST; Kraftverksteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; combined cycle; conceptual design; aerodynamic; mid-span design; through-flow design; oxy-fuel; SCOC-CC; OCC; gas turbine; Combined cycle; conceptual design; aerodynamic; mid-span design; Through-flow design; Oxy-fuel; SCOC-CC; OCC;

   Sammanfattning : The world is today facing a serious problem with global warming, which is heading towards an appallingly high temperature level. The greater part of the overall climate science community agree that global warming is caused by the greenhouse effect, which depends largely on emitted CO2 emissions from the combustion of fossil fuel.

   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. Advanced power cycles with mixture as the working fluid

   Författare :Maria Jonsson; KTH; []
   Nyckelord :power cycle; mixture working fluid; Kalina cycle; ammonia-water mixture; reciprocating internal combustion engine; bottoming cycle; gas turbine; evaporative gas turbine; air-water mixture; exergy;

   Sammanfattning : The world demand for electrical power increasescontinuously, requiring efficient and low-cost methods forpower generation. This thesis investigates two advanced powercycles with mixtures as the working fluid: the Kalina cycle,alternatively called the ammonia-water cycle, and theevaporative gas turbine cycle. LÄS MER

7. 5. Hybrid Solar Gas-Turbine Power Plants : A Thermoeconomic Analysis
