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

    Author : ADRIAN NILSSON DAHLQVIST; [2016-04-14]
    Keywords : 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;

    Abstract : 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.

  3. 3. Combined heat and power plant flexibility - Technical and economic potential and system interaction

    University dissertation from Stockholm : Energiteknik

    Author : Johanna Beiron; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexibility; Combined heat and power; Electricity price volatility; District heating; Dynamic modeling; Process optimization modeling; Combined cycle; Waste to energy;

    Abstract : The share of variable renewable energy sources in electricity generation systems is expected to increase, leading to increased variability in the load that must be provided by conventional power plants or other flexibility measures. Thus, thermal power plants need to consider implementation of technical measures that enhance flexibility; to maintain profitability of operation with increased electricity price fluctuation, and to support electricity system stability.

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

    University dissertation from Stockholm : Energiteknik

    Author : Egill Maron Thorbergsson; [2015]
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Advanced power cycles with mixture as the working fluid

    University dissertation from Stockholm : Kemiteknik

    Author : Maria Jonsson; [2003]
    Keywords : 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;

    Abstract : 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. READ MORE
