  2. 6. Advanced power cycles with mixture as the working fluid

    Author : Maria Jonsson; KTH; []
    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

  4. 7. Climate impact of the sustainable use of forest biomass in energy and material system : a life cycle perspective

    Author : Sylvia Haus; Johan Bergh; Bishnu Chandra Poudel; Krushna Mahapatra; Göran Berndes; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest residues; fossil fuel substitution; forest management; radiative forcing; land use change; climate change; bioenergy; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology; Byggteknik; Civil engineering;

    Abstract : Human society releases greenhouse gas emissions to the atmosphere while providing housing, heat, mobility and industrial production. Man-made greenhouse gas emissions are the main causes of climate change, coming mainly from burning fossil fuels and land-use changes. READ MORE

  5. 8. Analyzing technological change using experience curves - a study of the combined cycle gas turbine

    Author : Ulrika Claeson Colpier; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experience curves; technology assessment.; combined cycle gas turbine; electricity-generation costs; learning curves; technological development;

    Abstract : The aim of this thesis was to analyze and discuss the use of experience curves as a possible instrument for assessing future developments of a specific energy technology: the combined cycle gas turbine (CCGT). The CCGT technology is expected to figure prominently in future energy systems. READ MORE

  6. 9. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective

    Author : Lisa Näslund Eriksson; Leif Gustavsson; Antti Asikainen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest fuels; recovery systems; transportation; cost; primary energy use; CO2 emission; forest-fuel potential; life cycle perspective; Environmental engineering; Miljöteknik;

    Abstract : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. READ MORE

  7. 10. Modern Thermal Power Plants - Aspects on Modelling and Evaluation

    Author : Klas Jonshagen; Kraftverksteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; T-Q diagram; Combined cycle; heat- and mass-balance modelling; carbon capture; CO2;

    Abstract : The European Union (EU) has laid down very clear objectives for the reduction of greenhouse gases in the hope that it will prevent or mitigate climate change. Political incentives are used to make the power industry adopt changes in order to reach these EU targets. READ MORE
